The Dangers Of Mixing Marijuana And Cocaine

Combining drugs like marijuana and cocaine is more common than many people realize. However, mixing drugs can also be much more dangerous than people realize as well.

  • Marijuana & Cocaine
  • Negative Effects Of Marijuana & Cocaine

Two of the most often abused recreational drugs are cocaine and marijuana. It is not unusual for a person who is using cocaine to also be using marijuana recreationally. Combining the two is also not unheard of.

Many reasons are given as to why people mix cocaine and weed. Some individuals believe the two substances counteract, or eliminate, the negative effects of the drugs. Others think that the combination of weed and cocaine actually improves the ‘high’.

The reality is that pairing cocaine and weed together can result in serious side effects, and place the person at a higher risk of overdose. It is never recommended to mix marijuana and cocaine.

Marijuana And Cocaine

Cocaine is derived from the coca plant, and is classified as a stimulant. A cocaine ‘high’ results in euphoria, good feelings, positive mood and increase in confidence. Cocaine use also elevates the heart rate and blood pressure, which can lead to heart attack or stroke. Anxiety and paranoia may also occur with cocaine use.

Marjuana, or weed, consists of dried leaves, flowers and buds of the Cannabis plant. The chemical in the plant that causes the ‘high’ is delta-9-tetrahydrocannabinol (THC). THC is a psychoactive substance that affects people in a variety of ways.

Some people report a depressant reaction to THC, a relaxing or calming effect. Others indicate a stimulant effect, noting elevated mood, euphoria, anxiety or increased heart beat. In addition, marijuana also has some mild hallucinogenic effects.

Combining weed and cocaine is occurring for several reasons, the most common of them being:

  • assumption that euphoria will be intensified
  • expecting the depressant effects of marijuana to counter the stimulant effect of cocaine
  • coming down off cocaine will be easier due to the effects of marijuana

Meanwhile, there are several adverse effects and negative consequences of mixing cocaine and weed together.

Negative Effects Of Combining Marijuana And Cocaine

Decreasing the stimulant effects of cocaine with marijuana can result in an increased use of cocaine. Using larger amounts of cocaine consistently can result in cocaine dependence and addiction.

Both cocaine and weed can cause cardiovascular problems. A heart issue known as tachycardia is a side effect of both substances. Tachycardia can damage the heart muscle, cause heart attacks or blood clots, resulting in strokes. Combining weed and coke increases these risks.

Cocaine causes blood vessel constriction. When weed is mixed with cocaine, it prevents the blood vessels from constricting. Cocaine enters the blood system much faster this way, and can lead to accidental cocaine overdose.

Individuals with a cocaine addiction tend to experience more intense withdrawal symptoms if they are also using cannabis. Long term marijuana abuse often leads to rehospitalization for cocaine addiction or dependence.

Using cocaine and marijuana at the same time can result in increased levels of paranoia and anxiety, since these are the effects of both drugs on their own. It is never a safe or good idea to mix cocaine and weed.

Cocaine And Weed – In Closing

Mixing cocaine and weed is not a good idea, and can be fatal. Attempting to calm the negative effects of one drug with another can result in increased use and potential overdose.

The combination of weed and cocaine can cause cardiovascular damage, resulting in heart attacks, blood clots or stroke. Weed affects the availability of cocaine in the bloodstream, increasing risk for overdose.

Because marijuana blunts the effects of cocaine, an individual who mixes cocaine and weed are at more of a risk for developing an addiction, dependence or substance abuse disorder.

Overall, marijuana and cocaine should not be combined. The perceived positive effects are not so beneficial to outweigh the negative consequences. Mixing these two drugs is dangerous and should be avoided.

    No one has ever died from using marijuana. In fact, cannabis has helped countless numbers of people cope with anxiety, depression, epilepsy, and many other conditions and symptoms.

    Laced weed, however, is a completely different story.

    What can marijuana be laced with and how to recognize laced weed? Back to video

    Combining pot with other drugs and substances can be dangerous. Despite what some prohibitionists and scaremongers might want you to think, laced weed is actually rare and unusual to find. When the production and distribution of cannabis is regulated by the law (for either medical or recreational purposes), there’s usually no need to buy weed on the black market. That’s why, for example, Canada does not have as many problems with laced weed as some states in the U.S. and UK. However, not all of us have safe access to cannabis. In this article, we’ll investigate substances that are used for lacing pot, the effects of smoking laced weed, and how to tell if your weed is laced.

    What is laced weed?

    Laced weed is a cannabis flower that has been combined with other chemicals: drugs, inorganic substances or additives. You won’t believe what people are prepared to put in cannabis—hair sprays, pesticides, glass, and detergents are just some of the substances used for lacing cannabis.

    At this point, you might be asking yourself why on earth anyone would mix this powerful and healing herb with anything else? Well, there are a few obvious reasons. Shady dealers would do anything to sell you low-quality weed to make more profit. That’s why they would want to make it appear as high-quality and heavy as possible. Besides masking the low quality, lacing weed with other stronger drugs is a way for dealers to gradually get people addicted to the drug without them being aware of it, so they always come back for more.

    Another reason for lacing weed is actually no reason at all other than getting high. Some people like to sprinkle their weed intentionally with other drugs to make it more potent or to produce effects that weed normally does not have.

    If you suspect your weed has been laced with glass, just rub the bud on the surface of a CD. If the weed contains glass, it will leave scratches on it. Regular cannabis will not leave any scratches.

    Substances used for lacing weed

    Marijuana can be laced with almost any drug. Some dealers will intentionally lace weed with another drug to produce a different, more potent high. Let’s go through the most common drugs used for adulterating marijuana, what the effect would be if you consumed it, and why dealers and users do it.


    A packed bowl or a joint rolled with cocaine-laced weed is informally called Primo. People usually lace their weed with cocaine to induce the stimulant effect of cocaine and sedative effect of weed at the same time. Weed laced with cocaine can be dangerous. It affects your lungs, heart, and brain at the same time. If you have smoked a primo joint, you’ll probably have a sleepless night and a lack of focus, which will leave you feeling numb, which could result in paranoia. Tense muscles and an increased heart rate caused by the constricted blood vessels can, unfortunately, lead to fatal consequences: stroke, heart attack or even cardiac arrest.

    A joint laced with LSD is known as a rainbow joint. LSD or acid is a potent hallucinogenic drug that alters our awareness of surroundings, sensations, images, and feelings. Usually, it’s not addictive. The method for lacing weed with this potent hallucinogenic stimulant is different than other drugs. Rainbow joints are made by dabbing the end of marijuana cigarette into LSD, so when you put the joint filter tip on your lips and mouth, you absorb the substance. And that’s when the powerful hallucinogenic effects start. Even in smaller doses, this type of weed produces effects that can last up to 12 hours.

    Phencyclidine, better known as PCP or angel dust, is a strong hallucinogenic drug known for its mind-altering effects. Dealers usually add PCP to weed to induce a stronger psychoactive effect. This kind of marijuana is sold under different names such as dusted weed, wet weed, fry, and super weed.

    Smoking just small amounts of this compound can make you feel detached from your surroundings. This can eventually lead to aggressive behaviour with strong hallucinations, delusions, and even seizures, with the possibility of developing neurological damage.


    As one of the most addictive drugs out there, heroin is among the most dangerous substances on this list. Unfortunately, heroin-laced weed is not uncommon nowadays. Heroin is a yellowish, brown powder which smells like rubber or vinegar. By smoking pot mixed with this substance, you’ll become extremely relaxed and euphoric, but not like when you use regular weed. The high produced by weed laced with heroin produces a slow heart rate, slowed breathing and confusion that is almost unbearable.

    As ketamine became one of the favorite club drugs, it also found its way into rolled joints. It’s primarily used as an anesthetic in medicine, and it’s used recreationally because of its sedative effects. Ketamine can be very dangerous—dehydration, overheating, and confusion are just some of the symptoms.


    Methamphetamine is a strong and powerful neuro-stimulant medical drug used for treating ADHD and obesity, but it’s also abused for recreational purposes. It can cause serious effects, including hallucinations, delusions, and even seizures.

    Embalming fluid/formaldehyde

    Embalming fluid is a mixture of solvents (including formaldehyde), which is used to preserve dead bodies. Formaldehyde smells like pickles and has no color, and it’s usually added to synthetic weed. If you smoke weed laced with these substances you might experience pain in your chest, headaches and an increased heart rate, nausea and/or diarrhea, with severe hallucinations and paranoia.


    Fentanyl is an opioid drug used as a painkiller and anesthetic. It’s relatively cheap and is 50 times stronger than heroin. Fentanyl is a very dangerous opioid, and it would be more than stupid to mix it with any drug including marijuana.

    If you suspect you smoked a joint laced with PCP and you notice you talk indistinctly, blink a lot and look disoriented and paranoid, the best thing you can do is to seek medical help immediately. Photo by LARS HAGBERG/AFP/Getty Images

    Other substances marijuana can be laced with

    Believe it or not, weed can be laced with other materials and substances because they are much cheaper than some drugs and can easily make the weed appear more appealing to the eye.
