Recognize a real weed, a weed tampered with by spraying poisons and drugs ...

In the cannabis world, and especially on the black market, unscrupulous dealers produce doctored weed, which gives the illusion of better quality. Using the technique of spraying various chemicals, the herb in question will become unfit for consumption. The chemicals, drugs and contaminants used are toxic and create very undesirable effects. Learn to distinguish real grass from grass that creates the illusion... 

Signs of a tampered with weed

It can be almost impossible to tell if cannabis is mixed with a drug or other substance. Different varieties of cannabis have different colors. They also have different smells and tastes ... But, the color of the trafficked grass is obviously suspect. The pungent odor emanates from it, it is the warning sign of a contaminated (or pulverized) grass.

Colorado Chemical Analysis Laboratories report that the presence of contaminants in legal cannabis is not obvious to the naked eye. This is what a press release from theAmerican Chemical Society in 2015. The tests reveal the presence of fungi, butane and other contaminants in the cannabis which seemed normal ... But what is the point of selling an herb that creates disease or illusion?

Why is the herb mixed with other substances?

Most traffickers don't skimp with marijuana, mixing it with hard drugs, like methamphetamine or heroin. The goal of the maneuver ?! Addiction… Cocaine and heroin make a joint smoker hook, without doubt.

The main attraction of trafficking, of poisoning an herb is financial ...

Legal dealers are also likely to trick the weed with cheap substances to scam customers. They can mix it with detergent, perfume, or tiny shards of glass to enhance the scent, increase weight, or make the weed look more potent. But also, in certain cases, they will use ethanol, to create an herb that complies with European laws ...

Most of the time, people who use weed from the black market are more likely to come across doctored cannabis, according to the Center for Substance Abuse Research. The herb can be mixed with PCP or LSD to enhance the hallucinatory effects. Cannabis cigarettes are also dipped in embalming fluid for the same purpose. Marijuana can be mixed with other psychoactive drugs to produce various psychoactive effects, but also with various toxic contaminants to give the illusion of better weed:

Lead or other heavy metals

A recent article on reports that the potency of THC in marijuana marketed today is extremely high compared to that available in the 1970s and 1980s. Additionally, attempts to extract more THC to make edibles more powerful, lead to the addition of potentially dangerous compounds such as butane.

Check your state's regulations for levels of hazardous heavy metals such as cadmium (Cd), arsenic (As), lead (Pb), and mercury (Hg).

In addition, recent analyzes of the soil and substrate used to grow cannabis plants in states where it is legal reveal that the plants draw heavy metals from the soil. Attempts to develop more potent THC cannabis products also result in the presence of higher amounts of heavy metals and pesticides in the product.


There are analysis reports of herbs containing glass. Obviously, this situation can present a significant risk for the health of the people, even those making this style of product… We find this unfortunate trick in the cannabis to smoke, but also in edibles.

Spectacular trichomes, in glass ...

If you suspect the presence of glass in a cannabis bud, you can test it by rubbing it on a CD. Glass will scratch the CD, while unaltered marijuana should not scratch a CD ...

Fungi and bacteria

An article by also reports that in many cases even legal cannabis marketed in states like Colorado has high numbers of fungi and bacteria. Which can be potentially dangerous ...

Mushroom weed, or moldy weed; results from an involuntary act and a notorious incompetence in agriculture.

The mushrooms on a grass, tells us that the standards of culture, storage and marketing remain relatively poorly defined ...


PCP is a dangerous dissociative hallucinogenic drug. It is added to marijuana to produce a product with stronger or more varied psychoactive effects. According to a number of news reports, this has happened in situations where individuals were unaware that their cannabis had been altered. But it seems that in the majority of cases, the individuals who illicitly sell this combination do so without trying to hide it.

PCP, or angel dust, can be presented as a white powder or as crystals, capsules, tablets or liquid.

PCP added to marijuana can cause a number of potential deleterious effects. Including significant problems of hallucinations, delusions, confusion, aggression, suicidal behavior, convulsions, breathing problems… In other words, this combination develops serious neurological disorders.


People who smoke this substance become extremely lethargic and relaxed. They can develop potentially serious symptoms, such as reduced respiratory rate, heart rate, and confusion.

The herb is actually used to cure heroin withdrawal, addiction and overdoses ...

Obviously, heroin is a potentially dangerous drug. This substance becomes fatal when consumed in excessive amounts. People who do not use drugs regularly have a much lower tolerance than those who use them regularly. This can increase the risk of overdose or other serious problems.

embalming fluid

There are reports that marijuana has been mixed with embalming fluid (formaldehyde) for the purpose of producing specific psychoactive effects. For example to give the impression that the herb is more powerful than it is.

The embalming liquid, is essentially a mixture of formaldehyde, methanol and ethanol, is used more as a solvent for dissolving PCP ...

Obviously, this is a potentially dangerous situation that can lead to serious cognitive impairment. Like memory loss due to neurological damage and even potentially fatal effects.

Cocaine and crack

Mixing marijuana with cocaine (including crack) is often done to produce a unique set of psychoactive effects which include the stimulant effects of cocaine, combined with the sedative effects of marijuana. Often, individuals mix the drug for their own use. Marijuana is not commonly sold already mixed with cocaine. However, there are scattered reports that indicate this has happened.

Cannabis fights the toxicity of cocaine… The mixture is just as dubious as that with heroin.

People who smoke marijuana without knowing it is mixed with cocaine can develop a number of negative emotional reactions. This is because of the unexpected effects of using this drug… In addition, cocaine is a potentially dangerous drug, which itself can cause a number of adverse physical and psychological effects in people who use it regularly, such as the development of hallucinations, paranoia, seizures, cardiovascular problems, etc.

Laundry detergent:

Mixing marijuana with laundry detergent seems to improve its odor and overall appearance, so it looks better ...


Smoking marijuana mixed with laundry detergent can simply make you ill and cause serious complications.


LSD is a powerful hallucinogen that produces very powerful effects at very low doses. Mixing marijuana with LSD and then smoking it is unlikely to cause serious effects. Because LSD combined with heat will destroy itself. However, it seems that sometimes people dab the end of the marijuana cigarette in order to place the LSD on the edge of the lips…. The assimilation of the substance in the body is immediate, and develops powerful hallucinogenic effects.

In addition, LSD is completely odorless ...

It should be understood that LSD is an extremely potent substance and very small amounts of LSD produce hallucinogenic effects that can last up to 10-12 hours. Although LSD is generally not considered to have serious and significant physical consequences, people who are unaware that they are taking LSD run the risk of serious and emotionally upsetting "Bad Trips". This can lead to potentially serious consequences due to accidents.


In some cases, marijuana has been mixed with a powerful stimulant, methamphetamine (crystal meth). It can produce extremely powerful effects, including confusion, hallucinations, delusions and potential crises.

Methamphetamine is chemically related to amphetamine. But its effects persist on some brain systems, last longer and are more toxic.

Diesel gas

Some dealers will attempt to alter the smell of their weed by spraying it with diesel. It's a failed attempt to create that very diesel odor that is characteristic of some strains, like the Sour Diesel ou NYC-Diesel.

If you know a Diesel strain, you will certainly recognize the difference between the smell of the strain, and the smell of the gasoline pump ...


Alternatively, we sprinkle the cannabis with glass, as already seen. This gives the buyer the illusion that the buds are covered in sticky trichomes. Sometimes hair spray is also used to create this effect.

Grass, lacquered…


According to the verification agency Snopes, the reports of marijuana sprayed with fentanyl, a deadly opioid, is an urban legend ...

Fentanyl, the drug that makes you addicted and kills ...

However, in the United States, fentanyl is used extensively. The result is the famous opioid crisis that is ravaging Americans. The combination with the grass is only coincidental.


Stranger, the herb sprayed with ethanol would tend to comply with European standards, reducing the level of THC ... This technique is found mainly in herbs rich in CBD, for legal and European production ...

Some general effects of the trafficked marijuana

Stimulants added to marijuana will have stimulating effects… Central nervous system depressants added to marijuana will produce strong feelings of sedation and lethargy… Hallucinogenic drugs added to marijuana will cause hallucinations and delusions, etc.

Real weed cannot create a "Hangover" ...

In addition to these substance-specific effects, there are also some general side effects that can occur from using marijuana mixed with other substances. These more general effects include:

  • Consume marijuana and not feel any psychoactive effects following significant additions of inert vegetable matter, or ethanol ...
  • Have unusual feelings of nausea, vomiting, diarrhea, or other signs of illness.
  • Difficulty breathing, dizziness, lightheadedness, or a feeling that things are not real.
  • Finding of significant changes in heart rate or blood pressure.
  • Unusual sleeplessness, loss of appetite, unusual nervousness or agitation, or extreme irritability.
  • Psychotic effects, including hallucinations, delusions and marked confusion or disorientation.

Precautions to take

The majority of people who use marijuana for medicinal or recreational purposes do not expect to use marijuana mixed with another psychoactive substance. Obviously, each time that a mixture of various psychoactive substances is used, the practice can have a number of different effects, many of which can be potentially dangerous.

First precaution, avoid suspicious dealers ...

People who are not aware of what they are consuming are prone to serious emotional problems. This is because of the potential interaction of THC with other substances.

  • Never buy ground marijuana.
  • Never buy marijuana from someone who does not want the substance to be inspected by a potential buyer.
  • Thoroughly inspect the products before buying them.
  • Don't buy marijuana that looks or smells weird. For example, marijuana that smells like fuel may contain added substances, such as butane or other chemicals.
  • Don't buy marijuana that appears to contain unusual substances or is extremely shiny.
  • People who use marijuana for medicinal purposes should only purchase the product from reputable dealers.
  • Don't be afraid to throw away suspicious marijuana.
  • If possible, have the substance tested.


You will find this kind of weed that is tampered with and sprayed with chemicals, and toxic in places where cannabis is illegal. This is another reason for pushing states to legalize or decriminalize cannabis. We can negotiate, and get better quality weed, suited to our needs in states where cannabis is legal.

Unfortunately, the only way to know 100% if you are being cheated on is to consume (smoke) the herb in question. The cannabis connoisseur will then make the difference, with a real herb and end with the illusion ...

Secretly trafficked weed could destroy the dealer's reputation. Spraying the weed with chemicals or the like just isn't commercial and ruins the image of cannabis.
