Is your marijuana bad? 5 ways to tell if you’re smoking terrible weed
While many Americans can now buy and growВ marijuanaВ legally вЂ” choosing from an endlessly varied selection of premium bud вЂ” some still have to take it wherever they can find it. Even U.S. government researchers are forced to work withВ terrible weed.
You don’t want to get ripped off and smoke an inferior product, of course. So how can you tell if your flower isn’t up to snuff (or puff)? Believe it or not, you don’t need a doctorate in botany or chromatography instruments to tell whether your stash is shit. Read on, dear stoner, and learn some simple warning signs.В
1. It’s full of stems and seeds В В
A good rule of thumb in buying weed is that you want weed you can actually, uh, smoke. The stems of cannabis plants вЂ” though they may count toward the weight of your gram or eighth вЂ” are pretty much useless in that regard, so the less there are, the better. Seeds are even worse; they’ll literally explode when set on fire, potentially blowing out an entire bowl or ruining your joint. Even sellers of low-grade ganja usually won’t sell you stuff with seeds in it, but if you’re continually finding a few in each bag, it’s time to find a new source.
2. Its color, scent, texture and flavor seem off
In this sense, marijuanaВ is like any produce you might buy at the grocery store: You can just tellВ when it’s healthy and ripe for consumption. Good weed has more vibrant color, like a thriving plant. It has a heady, pungent aroma and taste. It’s somewhat springy, dense and coated with sticky, frosty, crystalline trichomes вЂ” tiny glands packed with THC, the psychoactive cannabinoid that gets you high. Bad weed, by comparison, looks like some junk you yanked out from underneath your lawnmower. It’s paler or duller in color, sometimes brown or yellowish. It’s often dry or more crumbly, and it lacks a distinctive smell (although sometimesВ it smells like hay orВ grass). It’s also sure to taste terrible. In certain cases, this kind of marijuanaВ may have been “blasted,” or entirely stripped of its cannabinoids to make butane hash oil. Either way, avoid it. В В
3. It doesn’t get you high вЂ” or makes you feel ill
Arguably the worst thing about bad pot is that it’s not very potent вЂ” which means you have to smoke a ton of it to feel anything like the high you’re after. In that case, you’re liable to get a headache before you’re even halfway stoned. Some users have encountered weed so crummy that it doesn’t seem to work at all. If you wind up with bud that only produces noxious smoke and induces a general nausea or cranial pain, what’s the point? Ditch that garbage and find out where the dank nugs are at вЂ” because you deserve better. В В В
4. It’s moldy, rotting or poorly cultivated
As with the food in your pantry or refrigerator, you’ve got to keep an eye out for mold and rot. These can afflict even decent marijuana, and they look like the mold and rot you’re used to finding on bread or cheese вЂ” furry discolorations on the surface. Packing this crap in your bong can make you seriously sick,В don’t risk it. Another visual red flag would be larger marijuanaВ leaves attached to your nugs, which indicates a sloppy “trim” when the buds were separated from the plant. Cannabis that gets trimmed by machines (as opposed to carefully trimmed by hand) may have diminished potency, as the trichomes are disturbed, and the leaves themselves don’t offer muchВ of the cannabinoid compounds that people prize in marijuana. В В В
5. It’s not actually marijuana
Almost every stoner of experience you’ll meet has a story about the time they bought weed that turned out to be anything but. It could be anything from crushed oregano to sage to basil to a wad of old, dried-out lettuce balled up in some cling wrap. Catnip is another popular pot substitute. If it doesn’t look like marijuanaВ buds, well, it’s probably not, so keep your wits about you. The best way to avoid this scam is to get your weed from someone you trust вЂ” and never, ever that friend who runs a YouTube prank channel. If he really insists it’s the good stuff, then he should have no trouble taking the first hit, right? В В В В
While many Americans can now buy and growВ marijuanaВ legally вЂ” choosing from an endlessly varied selection of premium bud вЂ” some still have to take it wherever they can find it. Even U.S. government researchers are forced to work withВ terribleвЂ¦
Cannabis Contaminants & How to Tell If Cannabis Is Laced
Prohibitive drug policy has a lot of negative consequences, including contamination. Luckily, as cannabis legalization continues, it’s becoming less likely to encounter contaminated cannabis. Occasionally contaminated cannabis or ‘grit weed’ does still crop up, and it’s best to know what’s in your buds and how to be sure.
The most common cannabis contaminants are industrial ones, which are virtually impossible to detect without a third-party laboratory analysis. However, these contaminants are a side-effect of the legalization of cannabis (growing in large scale operations). The illegal drug market on the other hand occasionally produces ‘laced’ cannabis, which is contaminated with substances used to make the bud look or feel stronger but may have negative impacts on health.
The only real way to avoid contaminated cannabis is knowing what kinds of contaminants are used and how to identify them visually and with tactile inspection.
Different kinds of cannabis contaminants
There are different ways to detect a contaminant depending on which one is used. The most common contaminants are Brix, sand, sugar and hairspray. They are all used to make a lower-quality batch of cannabis look better than it really is by making it heavier or “stickier” to the touch.
Aside from this, there are also industrial contaminants such as pesticides and heavy metals. It is very difficult for the regular consumer to identify these contaminants, which is why many companies provide third-party analyses on their products. Most contaminants, whether industrial or otherwise, generally decrease the quality of the overall cannabis experience and might even pose health risks to those who consume them.
1. Sand as a cannabis contaminant
When growing outdoors, attachments of sand and soil cannot always be avoided, especially not as the plant gets stickier while flowering. Sometimes, small materials such as sand can remain in the transportation medium such as a plastic bag. Nevertheless, cannabis is often intentionally contaminated with sand or quartz sand. This may make the bud appear more trichome-rich and may also make the bud heavier.
Inhalation of quartz (cristaline silica dust) or sand poses a threat of silicosis, a form of pneumoconiosis, which is a serious lung disease causing inflammation in the upper lobes of the lungs. However, onset of silicosis is usually only caused after large amounts are inhaled and over an extended period of time.
2. Sugar as a cannabis contaminant
Cannabis that tastes sweeter than usual could be infused with sugar. Standard glucose tests available in pharmacies using small paper strips can detect this instantly. Sugar is a commonly used as an “extender”, giving the plant more dry weight so that dealers can profit.
The sugar is dissolved in boiling water which, when it has cooled, is sprayed on the plants. The water evaporates leaving a sticky layer. If white sugar has been used, the buds may have a very pale appearance; brown sugar is also used as it appears closer in colour to mature trichomes.
Sugar is sometimes used to enhance tobacco smoking and is frequently added to tobacco during the manufacturing process. Thus, the effect of sugar inhalation has been examined in the context of tobacco smoking. Smoking sugars increases the levels if formaldehyde, acetaldehyde, acetone, acrolein and 2-furfural in tobacco smoke and significantly contribute to the adverse effects of smoking tobacco.
Although this has not been confirmed in the context of cannabis, it can be hypothesized that inhalation of sugar contaminants may cause many unwanted health effects for consumers.
The Difference Between Craft and Commercial Cannabis, And Why You Need to Know
3. Brix fertilizers used to “extend” cannabis
The true meaning of “Brix” is a unit of measurement to measure the weight of certain sugars and carbohydrates in plants. All plants require a certain degree of sugar and carbohydrates in order to grow and survive, and this includes cannabis. Certain chemical fertilizers are manufactured for the purpose of increasing Brix and therefore encouraging a growth spurt.
Brix fertilizers are sometimes used as a means of increasing the weight of cannabis. The buds are supposedly dipped in this fertilizer after harvest and then hung up to dry. Doing so makes the buds heavier and therefore the dealer has a greater profit margin.
It is very difficult to identify Brix as a contaminant as it is virtually invisible. However, buds may burn harshly and users may notice a chemical-like taste from buds that are laced with Brix fertilizers.
4. Hairspray as a cannabis contaminant
Hairspray is often used as a means of preserving old, dried out cannabis. This was perfectly exemplified prior to the renovation of the Sensi Seed Bank, where customers could see long colas that were perfectly preserved with hairspray.
Hairspray is also sometimes used to increase the aesthetic value of cannabis. Buds appear shinier, stickier and overall, stronger.
Naturally, hairspray is not recommended for inhalation. It is flammable for starters, and secondly, contains harsh chemicals that should not be consumed orally let alone inhaled. It is often easier to detect hairspray compared to other contaminants as it has a strong, chemically perfumed fragrance. Hair-sprayed buds also are prone to becoming hard and compact.
5. Industrial contaminants: fertilizers and pesticide
Fertilizers, pesticides and fungicides are often used in the growing process to protect against certain pests and stem rot. Although they are used for better growth, they often negatively affect the user of the final product and the natural environment. It is virtually impossible without third-party laboratory testing to identify the presence of fertilizers and pesticides. They are invisible to the naked eye and sometimes don’t even affect the taste of cannabis.
Pyrethrins (insecticides for plant protection and crop spraying) potentially lead to neurotoxicity (damage of the nervous system). They may also provoke serious asthma-related symptoms, although the connection between pyrethrins and asthma is yet to be confirmed.
Industrial contaminants are somewhat of a by-product of the legal cannabis industry. In order to maximize plant yield, deter pests and increase profitability, chemical fertilizers and pesticides are used. These contaminants are not characteristic of the black market for cannabis, although some clandestine growers will use such contaminants.
Industrial contaminants can be removed to a certain degree using a technique called flushing. This means that for the last stage of plant life, plants are not given fertilizers or nutrients but simply water, allowing the plant to flush itself from any nutrients or chemicals remaining in the flowers. However, this does not eliminate all contaminants and isn’t the most efficient method.

6. Lead splinters and lead dust
Lead, as a heavy metal, is intensely hazardous to health and therefore perhaps the most dangerous substance added to cannabis. Extremely difficult to spot with the naked eye because of their dark colour, lead splinters can only be identified under a microscope (a small pocket microscope for example).
Lead poisoning can lead to damage of the central and peripheral nervous system. It may affect the brain, liver, kidneys and bones and is particularly dangerous to an unborn foetus. Apart from a few exceptions, lead compounds are rated as hazardous to reproduction.
In 2007, the German city Leipzig reported 597 cases of users that smoked lead contaminated cannabis. Around 163 consumers had lead intoxication that necessitated treatment and 73 users had lead concentrations that required monitoring. Out of 160, 113 consumers were in need of medical treatment, and 35 were hospitalized. Lead is stored in the teeth and bones and can therefore take a long time to successfully flush it out of the body (sometimes up to 37 years). This video shows George Wurth from DHV (Deutscher Hanf Verband = German Hemp Alliance) giving a statement about cannabis lead contamination (available in German only).
7. Fungus as a cannabis contaminant
Mouldy and musty smelling, fungus infested cannabis is relatively easy to identify. Based on the degree of moulding, the cannabis can show white, furry dots. Mouldy cannabis usually occurs during the grow cycle or as a result of poorly stored and cured cannabis buds.
Mould spores can be threatening, especially for users that already suffer from allergies or asthma, or have a weak immune system. Also people with no previous health issues can experience symptoms like breathing problems, mucous membrane irritation and headaches.
8. Glass and glass splinters in cannabis
Pieces of glass in cannabis, mostly of industrial origin, can generally not be found with the naked eye, but they can be seen with a (pocket) microscope.
High temperatures (through burning) cause the glass particles to burst, whereby sharp-edged fragments can develop. Once in the respiratory system, they can cause damage from minute cuts. Scarring on the wounded tissue can lead to the lung disease silicosis, but only when cannabis contaminated with glass is being consumed continuously.
9. Talcum powder to change the appearance of cannabis
Talc is a matt white mineral that feels greasy, and is therefore often called soapstone. Cannabis coated with talcum powder is supposed to look more resinous and heavy, but it turns much lighter in colour also. Furthermore, it loses the typical cannabis smell.
Talc dust affects the respiratory system and bronchial tubes in a negative way. Excessive inhalation of talcum powder may cause respiratory illnesses such as pulmonary talcosis.
How do I know if my cannabis is contaminated?
Now that you know some of the common contaminants that can be found in cannabis, you are better equipped to pinpoint cannabis that has been laced. You have five senses, and if you can use all of them to inspect a piece of cannabis, you should.
1. Visual inspection
Before consuming a new batch of cannabis, be sure to closely inspect the bud, using a magnifying glass if necessary. Look out for whitish crystalline substances (that are NOT trichomes—the difference can be negligible with some higher-quality contaminants, so be careful!), as well as stems that appear to be caked in a foreign substance. Stems can often be a clearer indication of contaminants, as the fine particles can often be hidden among the irregular surface of the buds themselves.
Visual inspection should help you identify sugar or glass granules on the bud, as well as any mould or fungus that might be hiding in the bud or on the stems.
2. Tactile inspection
Rub a piece of bud or stalk between your fingers to test for the presence of spray. You may feel a chalky, dry texture, as well as individual grains of grit, glass or sugar. As well as using your fingers, you can also touch the tip of your tongue to the bud and then rub your tongue along your lips or the roof of your mouth to test for grainy substances. Be careful not to swallow any contaminants, as they could be harmful.
3. Taste and smell
The taste and smell of cannabis can tell a lot about which contaminants, if any, are present in the bud. However, you don’t always want to wait until smoking it to detect contaminants. You can smell the bud for anything that smells perfume-like in the way hairspray would smell perfume-like. You can also put your tongue on the bud. If it tastes sweeter than usual, it may be sugar coated.
4. Other methods of detection
- If you have already begun smoking a joint, you may assess the quality of the smoke itself. If the smoke is particularly harsh and chemical, it may indicate the presence of contaminants. As well as sprayed contaminants, it may also indicate mould or excessive, unflushed nutrients.
- Either way, if your bud tastes particularly bad or harsh, it may very well contain chemicals harmful to your health. Well-flushed, professionally grown cannabis should have a clean, juicy taste, so always pay attention to the flavour.
- Another very important means of detection is checking your ash. Some common contaminants, particularly building grit, cause the ash of cannabis joints to become hard and compacted, so that when the joint is tapped the ash remains in place. Such ash may also be very dark in colour, although this is not always the case.

General tips for detecting laced cannabis
Enlightenment and education – both Sensi Seeds goals – are crucial for protecting the consumer in all matters of cannabis. Listed below are a few general tips that can help recognize contaminated or laced cannabis and, hopefully, prevent the consumption of contaminated marijuana. Exercise caution when:
- the buds are suspiciously heavy
- the cannabis burns through like a sparkler or Shisha coal after lighting it up
- the burning tip of the joint gives off sparks
- a chemical, plastic-like smell develops while burning
- ash residues are hard and black and turn oily and greasy after light pressure
- the buds are particularly white and look coated in a crystalline or shiny substance
- buds are particularly crumbly and fluffy, and fall apart easily
- the buds do not dry out when kept exposed to air
- residue can be found in the packaging: granulate material, crystals, and sandy, powdery substances
Anytime cannabis is purchased, it should be examined for contaminants. Knowing that contaminated cannabis still circulates the market and that there are ways to identify it helps consumers to err on the side of caution when purchasing cannabis.
Help and information
Because of the illegal drugs trade, people injured by contaminated cannabis cannot just return or complain about their cannabis, or hold the seller accountable. That’s why it is crucial for users to be informed.
For this reason the DHV maintains an extender detector – a database of known contaminants – and an online platform on which victims can report their experiences.
The Cannabis College Amsterdam, a non-profit information centre based in the heart of Amsterdam, gives advice about everything related to the subject of cannabis. They also educate visitors about cannabis extenders and their dangers to health.
Several drug checking initiatives in Germany, Austria, Switzerland and The Netherlands offer the option of having drugs checked for certain substances such as cocaine, MDMA and ketamine. However, other substances such as magic mushrooms, cannabis and smart-products are not tested.

Approach to solving the problem of contamination
The legalization of cannabis is one approach to solving the problem of contamination. Theoretically, in a properly regulated system, plants could be cultivated under supervision and regulation. Consumers could obtain information and receive training. Production, distribution and consumption would be aligned with legislation.
The lawgiver would have more control over the quality of cannabis through decriminalisation and regulation of the industry as a whole.
Ultimately, the general legal cultivation of the plant for personal use, whether for medicinal or recreational reasons, would be a meaningful action in order to prevent the dangers of extenders in cannabis. All in all, these are qualities of a properly designed legal cannabis system.

Damn and I just bought $300 worth of product from one of my local dispensaries! I knew there was something up though when the bud was hard as a rock, very crumbly, didnt smell like marijuana either when I burned it, which now my lungs are hurting. So, I basically got ripped off, and am out all that money now, that sucks! Thanks!
What about the ones spraying reggie to trick their customers to think they’re buying loud!
Please could you tell us what reggie is? It sounds bad! I’ve never hear the word used in this context, but I haven’t lived in the UK for over 20 years so I’m out of the loop with quite a lot of things!
With best wishes,
Does anyone have any info on Thai cannabis/ weed?

BRIX is a term used to describe the sugar content of a plant – high brix content means high grade plant material, low brix content means poor quality plant material.
But there is also a product called Brix+ which is a sugar/plastic based substance used as a foliar spray to increase weight of buds and decreases the shrinkage of buds when they dry out, so they look like big fat buds but dont chop out to many bowls.
Is snake oil, you spray sugar on your plants and it drys out adding weight to the buds and makes them look as if they are covered in amber trycs
I am very thankful to you.This information very helps full.
I am having a bad problem with some bud. It has a heavy smell of what i think is a chemical smell. Has anyone else ever had this problem? When harvested, the plants smell amazing, and like they are supposed to. But once they are dried, its horrible. They are flushed prior to harvest, and washed once cut. Someone please help.

I am a conscious gardener.. what I have learned from being a Landscape and vegetable gardener is to know your farmer, landscaper, marijuana grower well.
A good tip is to get your weed from a small grower who you know doesn’t not spray their plants. Smaller more monitored rooms are less likely to need sprays. A am one of those growers. Happy to grow chemical free weed. I guess my answer may be obvious, and it’s probably not easy to find someone who doesn’t need to spread their plants. But those of you who are consumers should voice your concerns to grower that you don’t want weed that has been sprayed.
be aware there are Organic growers that use sprays that are concidered organic, in my opinion I wouldn’t want to smoke weed even if the spray is organic.
The goverments are evil.. They know damn well how harmless natural organic cannabis is and never ever legalized it. Now with this monsanto dupont strains beeing pushed, it became legal.. Uruguya is the first country that fully legalized cannabis, no wonder since they are the first labrats testing this MONSANTO crap!! Agaian, the goverments has sinister plans for cannabis users… TIME TO PROTEST WORLDWIDE! Also against all these illegal wars, just like out parents did during the 60’s / 70’s
Grow your own.. Enough is enough..
Hi, Brix is a sugar index rating of juices, pulled from a refractometer,you are referring to the Brix+ sugar-water product. Brix itself is good, as long as it is natural to the plant and not just sugar from a bottle. Brix is why people grow in soil va hydroponic.
I dont think I’ll be using Sensi seeds ever, they seem ill informed on the subject of growing, if they don’t know what Brix is. Let me assist with a copy/paste:
Brix+, AN Budcandy, Botanicare Sweet Raw/Citrus/Grape, GH Floranectar FruitnFusion/BlueberryDream/BananaBliss/PineappleRush/Coconut
CuttingEdge SourDee/Sugaree, Grotek PinaColada/Grapefruit/Blueberry/Strawberry/GreenApple Final Flush.
This is just a small taste of the fake-scent sugar-water products used on LEGAL, STATE APPROVED MEDICAL CANNABIS.
These products are mostly plant esters from industry scraps (peels, rinds) and simple sugars (table sugar) that soak right into the roots and into the plant fiber. These products contain other ingredients that may or may not assist your crop, mainly included to sell the idea that this is a fertilizer/nutrient supplement. It is not. It is a direct contaminant/adulterant.
The bottled product gives the plant the same exact smell of the product. A direct transfer, no chemical reactions or anything. The sugar adds useless sandbag weight, it does not increase yield. It inflames premature buds and gives them a whitish, frostier appearance. It hides minor cases of mold.
The growers who use this stuff are convinced by the fact that they waste so much money trusting opportunist salesmen.. Its a horrible case of debt induced delusion. It is absolutely no different than spraying your buds with honey water, or Coca-Cola. Youre just buying it premixed and sending it up the root for complete absorption.
When I lived in Northern California and Oregon, fruity strains tasted absolutely amazing. When I moved to Colorado/Az, I discovered the fake weed. Spending meticulous hours cleaning my vaporizers,and tossing more “Cannabis” in the trash than I was consuming. The state health departments do not care one bit.
Not only is the marijuana contaminated with fruit scented sugar water, it is contaminated with nut products and lactose products,in the form of mold hiding sprays and feeds. I have seen ONE peanut allergy warning. I have no idea why peanuts are being used, but Neem nut oil is on a large percentage of legal market Cannabis, as a mold deterrent. Many dispensaries pass the smell of processed Neem oil and rotted milk spray off as terpenes.
Those are not the only unnatural smells found in legal medical Cannabis. A lot of the product can be seperated into groups by the line of nutrient it was grown with. I call smell Botanicare PBR on a large portion of the flowers. Several others I can group but have yet to identify. The smell and color can be consistently seperated in some dispensaries, the buds are so heavily contaminated.
Not much else to say. Its illegal to grow your own MMJ in Arizona, where this problem is worst. Arizona dispensaries have the worst Cannabis I’ve ever experienced. That is including tons of bricked up seeded import. Hardly any of it taste like Cannabis varietals. It all taste like lawn clippings and grow products. I suggest people grow their own despite the illegality of home production.
This is what legalization gets us. Smart people were asking for decriminalization. The corporations sponsored legalization. The retailers grow the product themselves, they have exclusive production rights and zero regulations. It is absolutely disgusting on all accounts!
Thanks for your comment. This sentence: “Brix is a sugar index rating of juices, pulled from a refractometer,you are referring to the Brix+ sugar-water product. Brix itself is good, as long as it is natural to the plant and not just sugar from a bottle. Brix is why people grow in soil va hydroponic.” does not entirely make sense; in Europe, where Sensi Seeds is based, the product is referred to as Brix and I am unfamiliar with the “sugar rating” you refer to by that name.
Interesting to hear about the contaminants in legal medicinal weed in the US though, thanks for sharing.
With best wishes,
Hey, i know brix as a naturel sugar rating of the inside of plantcells with a brix reader. (The higher the naturel sugar rating is getting the better u will flower. But also as a sugar/plastic substance. Found multiple collors en sizes. Rock solid /dont disolve, burns black. Easy to spot with a proper digital usb camera. Almost everything i buy is contaiminated here in holland. Rarely i see proper organic grow, if poeple knew they don’t have to do so much for the plant, but let nature do it. It will be a easy grow and the best u ever had.
Eggzectly why I voted no for rec weed in Cali! A dez-gusting power grab by Monsanto and the tobacco corporations is about to ruin the party big time….but I had no idea that sheet was already in effect in AZ. Billionaires ruin everything. 🙁
I live i Az and all the MMJ is contaminated. Its illegal to grow my own. The corporate takeover of Cannabis has sponsored this experiment. Testing the waters to see what sells. ALL KINDS OF BULL SHIT SELLS. Wax pens made from scrap reclaim and fake terps. Moldy buds soaked in h202,neem oil, rotten milk, etc. Buds with zero smell and taste other than plant matter. Buds you can line up by color and smell according to nutrients used (Budcandy, Sweet, Sour Dee, Floranectar, Carboload, all these “sweeteners” are a curse, used as flush-ins for giving lawn clippings a smell)
Legal weed is a JOKE! I haven’t smelled actual weed in any dispensary. Its all Cutting Edge, Botanicare, AN, GH product lines I smell instead! Monsanto fake weed BULLSHIT.
Why is the seedstock so poor that dispensaries cant grow mold free buds, or buds without artificial smells? Do I need to mention Monsantos connections again? We all know who works with the DEA in collecting Cannabis genetics. And we all know who pushed “sensi” as a standard of quality, rather than quality as a standard of quality..
I am sick of this American capitalist fake jew weed! Bring me some hash that actual tastes like hash! Forget this M39 bullshit sprayed with “Uncle Johns Blend” and labeled “super skunk chem dog diesel” !
Finally! Someone knows there is sprayed shit everywhere. All Madrid clubs sell crap, all UK full of crap (except homegrown by friends) all Europe hash has black smoke if set on fire. Poisoning all weed smokers who dont supply themselves. CHECK YOUR BUDS PEOPLE.
Despite a legal cannabis market, some growers still intentionally lace buds with contaminants. Learn about them and how to identify them in this article.
