Laced Weed: Symptoms, Dangers, and What to Do

Laced Weed: Symptoms, Dangers, and What to Do

Marijuana, commonly referred to as weed, is a widely used recreational substance. However, there have been concerns about the possibility of laced weed, where marijuana is mixed or contaminated with other drugs or nonpsychoactive substances. The effects of laced weed can range from minor discomfort to serious health risks. In this article, we will discuss the symptoms of laced weed, the reasons behind lacing marijuana, the potential effects, and what to do if you suspect you have smoked laced weed.

If you or someone you know is experiencing a health crisis due to marijuana, please call your doctor or contact emergency medical services.

Understanding Laced Weed

Laced weed refers to marijuana that has been secretly mixed or contaminated with another substance. Some dealers intentionally lace weed to deceive and rip off customers, while others contaminate marijuana to make it appear more potent. Various substances can be used to lace weed, including embalming fluid, glass, laundry detergent, methamphetamine, heroin, PCP, fentanyl, and LSD. It is important to note that the effects of laced weed can vary depending on the specific substance it is mixed with, the method of consumption, and individual factors.

Symptoms of Laced Weed

Identifying laced weed can be challenging as different strains of marijuana have different colors, smells, and tastes. However, certain symptoms may indicate that marijuana has been laced. An unusual color or pungent smell could be a warning sign. Simple tests, such as rubbing marijuana against a CD to check for scratches (indicating the presence of glass), may also provide some clues. However, it is important to note that many impurities and contaminants are undetectable through DIY tests. Chemical testing labs have discovered contaminants in legal marijuana that were not visible to the naked eye, emphasizing the difficulty of identifying laced weed.

Why Weed Is Mixed with Other Substances

While most dealers do not lace marijuana with hard drugs like meth or heroin to sell it to unsuspecting buyers, they may mix it with cheap substances to deceive customers and increase profits. For example, laundry detergent, perfumes, or tiny shards of glass may be added to enhance the smell, increase the weight, or create the illusion of a more potent product. Cases of marijuana being laced with hard drugs are rare but not nonexistent. Some individuals who use marijuana may also lace it with other substances to enhance its effects, such as PCP or LSD.


Laced Weed Side Effects

Laced weed side effects can vary depending on the specific substance it is laced with. Stimulants like meth or cocaine can induce feelings of energy, intense focus, and extreme happiness. Downers such as heroin may cause lethargy, nausea, or excessive relaxation. Hallucinogens like PCP or LSD can lead to hallucinations and altered perceptions. Other contaminants, such as glass, laundry detergent, or fungi, can cause uncontrollable coughing, vomiting, or pain. It is important to note that laced weed can have different effects from regular marijuana use, and these effects may be unpredictable and potentially harmful.

What to Do if You Smoke Laced Weed

If you suspect that you have smoked laced weed and experience laced weed symptoms that make you worried or uncomfortable, it is crucial to seek medical help. While a marijuana overdose is not fatal, lacing with other drugs can lead to potential overdose or adverse effects. If you are with someone who is sober, ask them to take you to the hospital. If you do not have a safe ride, you can call a marijuana hotline or a poison help line for assistance. These services provide immediate help for people experiencing unpleasant side effects or addiction-related concerns. In case of laced weed symptoms indicative of a drug overdose, such as rapid heartbeat, slowed breathing, confusion, paranoia, slurred speech, or drastic changes in body temperature, call 911 immediately.

The Risks of Laced Weed

The risks associated with laced weed can be significant. Consuming substances that are laced with unknown or potentially harmful drugs can lead to serious health consequences. Laced weed side effects may be unpredictable and can range from mildly uncomfortable to life-threatening. Lacing marijuana with substances like methamphetamine or fentanyl can pose significant risks, as these drugs can be highly potent and have the potential for overdose. It is important to remember that using laced weed is a gamble with your health and well-being.

Avoiding Laced Weed

To minimize the risk of using laced weed, it is advisable to obtain marijuana from legal and reputable sources. Licensed dispensaries and regulated markets ensure that the marijuana undergoes proper testing and quality control measures. Purchasing from trusted sources reduces the likelihood of unknowingly consuming laced weed. Additionally, educating oneself about the symptoms of laced weed and understanding the risks associated with purchasing from illicit or unreliable sources can help individuals make informed decisions and prioritize their safety.

Seeking Support and Treatment

If you suspect that you may be struggling with addiction to laced weed or any other substance, it is important to seek professional help. Substance abuse and addiction are complex issues that often require specialized treatment. There are various treatment options available, such as detoxification, inpatient rehabilitation, outpatient programs, and counseling. Seeking support from healthcare professionals, addiction specialists, and support groups can provide guidance, accountability, and resources for recovery.


Laced weed is a concerning issue that poses potential risks to individuals who use marijuana. While it can be challenging to identify laced weed, being aware of the signs and risks associated with lacing can help users make informed decisions. If you suspect and experience laced weed symptoms that cause concern, it is crucial to seek medical assistance promptly. Prioritizing safety, obtaining marijuana from reputable sources, and seeking professional help for addiction-related concerns can contribute to a healthier and safer experience with marijuana use.

Remember, your well-being is paramount, and making informed choices about substance use is essential for maintaining a healthy and fulfilling life.
