Health Information
- Reliable research is still fairly limited. There is some evidence that controlled use of cannabis has potential benefits. Misuse has real health risks.
- Evidence does show consumption of cannabis has an impact on executive function for 7 hours to 20 days in those who have smoked at least 1 day in the last 30.*
- Therapeutic effects may be myriad and are experienced differently by different people. You should consult with a medical provider about your medical symptoms and various ways to treat them.
- Despite myths, cannabis can be addictive.
- Marketing of cannabis to treat many conditions is often misleading and use can make the conditions one is trying to treat worse.
- As with any medication or substance, side effects and outcomes of use will vary depending on several factors, including dosage, frequency of use, method of use, genetics, physical and mental health, and personal life history and context.
Harm Reduction Actions
- Avoid cannabis smoke if possible as it contains tar and toxins. Vaporizers are a safer choice.
- Approximately 95% of the THC in cannabis smoke is absorbed in the first few seconds so short puffs are sufficient. No need to hold it in; that just allows more particulate matter to settle in your lungs.
- The water in bongs filters out more THC than tars so joints are safer. The plastic and/or rubber in pipes and bongs give off toxic fumes.
- Motor coordination, judgment, and other skills are impaired with cannabis use. Wait three to four hours after using cannabis before driving.
