There can be some shady things going on in the marijuana scene or any subculture for that matter if you do not know what to watch out for. Being street smart is an important part of being a safe stoner; there can be detrimental effects stemming from misinformation. In particular, dangerous instances have happened due to laced weed. Stay tuned to learn more about how you can become much more aware and prepared for any shady business.

What is Lacing?

The act of lacing involves combining two or more substances. This is common among drugs such as cocaine resulting in bulkier products. This is usually done to get a higher profit because these commodities are usually priced according to their weight. In other instances, this is done to boost or lessen the psychoactive effects of the drug. These blends have caused numerous overdoses.   

While cannabis is not usually laced with other drugs or substances, these cases are a possibility. Marijuana sold from unknown sources or unregulated brands or places could land you in heaps of trouble with such problems as laced cannabis. Low-grade weed has also been laced with drugs, in some cases, to enhance its psychoactive effects. Drugs like cocaine or fentanyl have been added to marijuana which can cause vomiting and paranoia while marijuana cigarettes have also been dipped into embalming fluid for the same reason but could likely cause pain in the chest, hallucination, and paranoia. 

Although there are not many available statistics on how much weed gets laced, news reports can attest that this is something cannabis users need to be vigilant about. Care is needed so as not to buy your stash from a clandestine source.

What Can Weed Be Laced With?

Just about anything can be mixed in with cannabis which stimulates similar effects or visuals. Since the goal is to add weight to marijuana in a cheap way, these additional materials are usually cheaper or have been obtained through illegal means for too-good-to-be-true prices. As such, here are some substances that could be combined with your weed should you purchase a seedy, laced batch. 


Lovingly called angel dust, Phencyclidine is anything but a soft touch on your piece of weed. It is also known as PCP and can give marijuana a substantial boost in its psychoactive effects. Marijuana with some mixed in PCP is called fry, superweed, dusted weed, or wet weed.  


Cocaine is sometimes added to weed for its stimulating properties so that the user can experience both the sleepiness you get from a toke of marijuana alongside the energy of the cocaine. The new product is casually referred to as Primo. Primo can have harmful effects on the heart, lungs, and brain simultaneously. You can feel numb after some puffs, heightening paranoia. Your heart rate can increase and constrict the blood vessels which can result in a heart attack, stroke, or cardiac arrest.  


Marijuana laced with LSD is called a rainbow joint. Do not be fooled by its colorful name. While this extra can make for a very potent product, it will change your perception of your surroundings, images, sensations, and feelings. The consequences can be detrimental such as delusions or seizures. Damage to the brain is likely and aggressive behavior is another effect to be careful about. 


Heroin is infamous as a drug due to its addictive nature. It is one of the most destructive substances on this list due to its effects on the heart. It can put your heart rate at a crawling pace causing confusion and slow breathing. The yellow to brownish powder can smell like vinegar or rubber, one hinting at the difference from regular weed to laced weed. While it makes the user experience a high, it does not cause an uplifting happy feeling but causes the heart to slow down.


The opioid, fentanyl, is utilized as an anesthetic or painkiller. It is marked as a cheaper drug than heroin but with 50 times more power. This one is ever more dangerous than Heroin and can produce adverse effects. Possible overdoses have been attributed to the combination of fentanyl with weed.  


Ketamine is mostly used for anesthetic purposes in the medical field and sedative purposes in recreational use. It can cause dehydration, confusion, and overheating when added to marijuana, adding another layer of concern. 

Other Additions Used to Lace Marijuana

The previous list of substances is not the only ones that have been combined with weed to bulk it up or to boost its effects. Here are some other materials you might want to watch out for: 

  • Food coloring
  • Crushed glass
  • Laundry detergent
  • Fungus and bacteria
  • Embalming fluid
  • Methamphetamine
  • Fuel additives and other smell adulterants
