Experts are continuously exploring the implications of exposure to secondhand cannabis smoke, particularly in vulnerable populations like children, pregnant individuals, and those with chronic diseases. While the intoxicating effects of tetrahydrocannabinol (THC) can vary, exposure to other people’s cannabis use raises questions about its potential impact. This article explores the dynamics of secondhand marijuana smoke and its effects on individuals.
Can You Get a Contact High?
Studies indicate that while theoretically possible, the likelihood of experiencing a “contact high” from inhaling secondhand marijuana smoke is relatively low. The term refers to a sober person feeling the effects of recreational drugs when in proximity to someone under the influence. Factors influencing this include proximity to the smoker, the THC level in the marijuana, and the quality of ventilation. Close contact with highly concentrated marijuana smoke in poorly ventilated spaces increases the chances of a contact high.
Comparison with Tobacco Smoke
Right now, there’s limited clinical data available to confirm whether can you get second hand high from marijuana smoke, and whether it is as harmful as secondhand tobacco smoke. Interestingly, a 2016 study on rats suggests that even brief exposure to secondhand marijuana smoke can impair lung function for an extended period, surpassing the impact of tobacco’s secondhand smoke.
Drug Test Concerns
Secondhand cannabis smoke could potentially result in a positive drug test, depending on the level of exposure and the ventilation in the environment. Small, poorly ventilated spaces with heavy cannabis smoke increase the likelihood of drug test failure. Studies have shown that children exposed to cannabis smoke at home may have detectable levels of THC in their urine, emphasizing the potential for positive drug tests due to secondhand smoke.
Side Effects and Symptoms
While a contact buzz is uncommon, exposure to secondhand marijuana smoke may lead to various side effects. Here are some contact high symptoms :
- Delayed Reflexes: THC in the blood, even from second hand dab smoke, can slow reaction times.
- Dizziness: Prolonged exposure may cause lightheadedness.
- Lethargy: Some individuals may experience tiredness or lethargy due to the calming effects of THC.
Effects on Children
Research on children exposed to secondhand marijuana smoke has shown biological evidence of exposure in almost half of the studied cases. Although there’s no conclusive link to health issues, the presence of harmful chemicals in marijuana smoke (which may be harmful to children) raises concerns.
Conclusion
While contact highs are rare, caution is advised, especially for pregnant individuals, nursing mothers, or those with mental health conditions. Ongoing research is crucial to fully understand the comparative risks of secondhand marijuana smoke, but the existing evidence underscores the importance of minimizing exposure to it.
