Laced Weed vs Regular Weed

 What is laced weed?

A weed is laced when other substances are added to marijuana e.g. fentanyl. Lacing occurs when additional substances are added to the cannabis to mimic stronger strains. In most cases, it is the users who will most likely lace their weed with things such as cocaine and PCP. They also might use a marijuana concentrate e.g. shatter to enhance the marijuana’s effect.

There are also some other substances that may be used:

Substances Weed Can Be Laced With

  • Cannabis concentrates like dust, glass, or shatter
  • Cocaine
  • Ether
  • Carfentanil (powerful opioid)
  • Glass (contamination to mimic trichomes)
  • Heroin
  • Ketamine
  • Laundry detergent to create false smell like lavender
  • Butane
  • Gasoline
  • LSD
  • Methamphetamine
  • PCP
  • Spice (fake, synthetic cannabinoids)

Substances like mold, bacteria, glass and butane can get mixed with cannabis, which can lead to poisoning or an allergic reaction.

Why do people mix Cannabis with Other Substances?


It is likely that the main reason for this is to increase profits by using cheap weed to give the impressions that THC-rich trichrome are present. This usually means that it contains lethal glass.

This practice rarely happens due to the fact that people start to cough up blood and don’t go back for more.


It has been reported that detergent has also been found in laced marijuana. Why does this occur?

It happens when you take a cheap blend of cheap weak marijuana and add detergent. It then starts to resemble more popular expensive strains.


Butane is used to create concentrated weed, and maybe contaminate the process. You can get a small amount of Butane, even from a lighter, but do not try and consume too much of it. A little is not always harmful.

Mold and Bacteria

Mold and bacteria (which is unintentional) will spoil your weed, and may also cause infections and allergic reactions. Be sure to throw out any moldy or bacteria-filled weed immediately. You don’t to get sick.

Cocaine Laced Weed Effects

Weed, generally, will not be laced with anything expensive like cocaine. This is because cocaine is very expensive and they will lose money if they did it that way. However, people who use marijuana may lace it with cocaine for a much more powerful effect. If you buy it legally, it will always be safe to use as it won’t be laced. Most users do it themselves and lace weed with cocaine. This should be avoided as it can raise the risk of getting paranoid or experiencing a heart attack.

PCP Laced Weed Symptoms

PCP is a hallucinogen and anesthetic, which was declared illegal due to serious side effects of altered behavior and hallucinations. It is reported that it is used to freak people out. This idea was made famous in the movie Friday when the main character was smoking weed with strangers. They didn’t tell him that he was smoking PCP laced weed. He ended up suffering from delirium and hallucinations, and ended up stuck in a chicken coup acting very strangely.

PCP is a dangerous substance and causes delirium and abnormal behavior. It is a drug that is infamous in many murder and strange crimes cases.

Marijuana Concentrates

Dust and keef are weed concentrates that can enhance the effect of your week. Users often add these concentrates to their own weed to get even higher. People who suffer from chronic conditions may also do this their pain and other symptoms.


Blunts can be dipped in Ether, PCP or Formaldehyde and these are often called an embalming fluid. These kinds of fluids help dissolves the CC. Ether is a type of anesthetic.

This sherm (combination) can be very dangerous and leads to bad side effects including vomiting and hallucinations.

Carfentanil and Heroin

Users also may use opioid laced cannabis with heroin. Their heroin may also be laced with cartentanil, a chemical used to tranquilize elephants. This is a major cause of death in young people in the United States. They do not need additional use opioids.

So, if you have weed to treat your chronic pain, don’t make it worse by lacing it with heroin or carfentanil.

Ketamine and Weed

Ketamine is used like PCP and comes from vets to tranquilize horses. It is also used to manage chronic pain in children who suffer from Complex Regional Pain Syndrome. Ketamine is fast acting antidepressants, which is similar to NMDA and PCP. Ketamine is also a known hallucinogen and it might make your experience very negative if you place your weed with it. There are doctors around the place that use ketamine is treat severe chronic pain. You should consult your doctor if you are using Ketamine as it is very dangerous.


LSD is a drug that makes you hallucinate. The danger lies in the fact that you might have a bad trip. It depends on how much put in the marijuana. The bad trip may last up to 12 hours and it is something that you should avoid.

There are several clinical trials that are using legitimate ways to get treated with LSD. A visit to and you will be able to trials that are using LSD. Don’t use LSD and weed at the same time.


A dealer will not lace weed with methamphetamine is extremely expensive compared to marijuana. Do not use it together with weed, please don’t do it. Meth is extremely dangerous and you should avoid it at any cost. It can destroy your mind and body, and make it almost impossible to sleep after its use.

It can also cause trauma to your kidneys and easily causes paranoia in some people. Weed is a safe drug, we want it to stay legal, so please don’t mix it with illegal drugs.


Dealers may lace your weed with Spice or K2. These are quite powerful; they also mimic the more expensive strains and are cheap. Spice is very dangerous compared to marijuana, so it is best avoided. It is associated with the onset of seizures and admitted to hospital. It contains many unknown synthetic cannabinoids that have serious side effects when taken.

What are the Side Effects of Laced Weed? Marijuana

This depends on what the weed is laced with, however, if it is laced with anything illegal, you could be charged with a crime.

The Side of Effects of Laced Weed

It really depends on what substances that were used in the process. We know that marijuana is now getting legalised, it is best not to lace it with illegal drugs as you can still be charged by the police.

Also, when you mix weed with hallucinogens makes things very dangerous. Weed has very mild side effects, but when it is laced with PCP or LSD, it has side effects that can lost after the weed has worn of, leading to dangerous behaviors and is often fatal. Cocaine is associated with heart attacks and other drugs like Fentanyl because of serious side effects like weightless, sleep deprivation and hallucinations.

Precautions to Take

You need to avoid buying marijuana that is laced with illegal substances. You can do this by:

  1. Don’t lace your cannabis! This will compromise the legality of your weed if you lace it with illegal substances.
  2. When you buy your buds, do your best to make sure that it is still intact.
  3. Marijuana that is ground may be already laced with an unknown substance, so make sure that you buy it from reputable suppliers.
  4. Make sure that you check out the marijuana before you buy it. Do not buy marijuana that smells off or like chemicals, but if you smell an embalming fluid, the weed could be laced.
  5. Do not smoke marijuana with strangers.
  6. Do not buy marijuana that has lumpy substances in it. Real trichomes feel like resin, and they aren’t really scratchy like glass.
  7. You can get your weed tested in the lab to check for mold, drugs and bacteria.

Laced weed will either not smell like regular weed or will have an exaggerated smell in an attempt to mimic more expensive weed smells. You may smell or taste butane, washing detergent, mold, or decay. Discard any such weed immediately.

It may have a harsh, chemically taste rather than the chlorophyll dense plant taste you are expecting.

 How To Test For Laced Weed

Take a Close-Up Look at your Bud

Examine your bud that you have bought. The first thing to do is to test your weed and have a closer look with your naked eye. You should make sure that there is no powder, rot or mold. You have to make sure that the buds are dry, and you can do this by rolling the buds between your fingers. You could also use a microscope and have a look at your weed.

Test for Crushed Glass

Why would someone put crushed glass in weed? When your marijuana is legitimate, all that glassy parts are called trichomes; they are part of the plant’s immune system. These parts are made up of THC and CBD.

We can see how this plant has evolved through the centuries. The plant has come to rely on insects to pollinate the plants, so having this ability to control the behavior of animals made marijuana a very successful plant species.

Crushed glass can look like trichomes, so someone who is unethical may try to add glass to the weed to mimic trichomes. You can test the weed by trying to use it to scratch it with your weed; real trichomes will not scratch a CD. You can feel for the texture of glass, too.

Test for Laundry Detergent and Fuel Additives

Why do dealers add detergent to weed? This can be done in order to make a cheap strain appear more expensive. Of course, you wouldn’t want consume detergent that contains poison and strong chemicals.

Why do dealers add fuel additives to cannabis? This is to make the cheap strain look more expensive. Bad dealers will lace their weed with gasoline or other chemicals to mimic a potent smell. There may be remaining Butane left after the processing of the weed.

Here is what you do, you can store your weed in a locked container or bag. You can open it up and take a deep breathe. If it smells like gasoline or detergent, then it probably has been laced with gasoline. You could try burning a piece of bud and look at the remaining ashes. If the ash is contaminated it will clump up. Get rid of any weed that shows signs of contamination.

How to Tell if Weed is Laced with PCP

When weed is laced with PCP, it will be hard to ignore the embalming fluid smell coming from the weird.  It has a strong chemical odor that you won’t miss. We have some advice on what to say about testing weed for PCP.

What to Do if You Smoked Laced Weed

The odds are that you won’t get laced weed due to the fact that is a chapter drug and sellers aren’t willing to lose money by lacing weed with drugs like cocaine. Your friends may lace your weed as a practical joke.

If you freak out after you noticed the weed is laced, you might be freaking out. Make sure you monitor how you are going so that you will be stable and healthy. Keep in mind that your body has many tools at its disposal to deal with contamination.

What Do I Do?  I Smoked Laced Weed:

  1. Please do not panic, many of your symptoms are likely the result of panic and not from the laced mixed.
  2. You should tell someone ASAP. Tell a friend or family member to monitor how you are doing for at least a couple of hours. If the weed is laced with a harsh chemical, it may be lethal, so please report to your local hospital for immediate treatment. If you are given laced weed, make sure that people don’t take advantage of your in your altered state.
  3. Go to a place, which is safe for you. You have a support person monitoring you, so you should stay inside and away from the general public. Go home and rest until it settle. If your symptoms worsened, please go to the local Emergency Department and seek medical advice
  4. Avoid the urge to take additional drugs or medication, as it might make things worse (drugs can interact with each other). If you are in need, please get your doctor to administer the medication. You should do your best to contact Poison Control as they know what to do. If weed is legal in your state, take it with you for testing.
  5. Let it out. If you feel like vomiting, let it out, and definitely get to urgent care, ER, and call poison control and ask them what to do. If you can’t do this, that’s why the first thing you did is call a friend or family member. They will do it for you.
  6. Go to the ER. If you’re not sure what was in it, go to the ER, and if weed is legal, take it with you for testing. See our site here to see if weed is legal in your state:

Now that you’re at the ER for poisoning, you have a bit of a pickle to consider. If weed is illegal where you are, what do you tell them?

Issues facing you with Laced Weed

A simple reason why people avoid going to the Emergency Department is that they are scared they may be prosecuted if they have smoked laced week.

In this scenario, the person having symptoms from laced-weed is in a state where marijuana is illegal. They call their friend, and they go to the ER. The patient is asked what is wrong, and it should be an honest upfront answer. The doctor can’t breach patient-doctor confidentially, so they won’t tell the police. Can the police prosecute you? Not likely, but sometimes the cops can break these rules.

To extend this scenario, what if you went into seizures before you could reach the hospital and had to call 911.

The police may arrive with the paramedics; the cops could charge you with a drug possession crime. Normally, they won’t charge you if you have already consumed the drugs. If you give laced weed to someone who is ill, you might be charged with a crime.

There are Samaritan laws in places that may protect you from prosecution. There is ignorance on both sides, so you may go to prison. You need to see a lawyer, and they will help you go home without getting convicted. You should seek help from your network of friends; just hide the evidence before they come over.

You don’t need to tell the cops anything, but be sure to tell the paramedics everything and sue them if they breach this. Google your rights and be sure to call 911 before you do you research as time is of the essence.

There is another scenario. If you are living in a state/place where marijuana is legal, there are still some issues surrounding the admission to hospital. It can be grey area. In most cases, anyone who prosecutes who for smoking laced weed is breaking the law. Get a good lawyer and know your rights. Stay calm as police will often back down once you make known you know your rights. Next time, buy your weed from a reputable organization.
