Marijuana is a psychoactive drug from the Cannabis plant intended for medical or recreational use. It can be used by smoking, vaporizing, within food, or as an extract. It is often used for its mental and physical effects, such as a “high” or “stoned” feeling, a general change in perception, euphoria (heightened mood), and an increase in appetite. The onset of effects is within minutes when smoked, and about 30 to 60 minutes when cooked and eaten. The effects last for between two and six hours. But marijuana actually stays in your system longer than that.
Underestimating how long marijuana remains detectable can have serious consequences for people on parole or probation or workers subject to regular drug-testing. The length of time it remains detectable depends on how much and how often you use. In general, moderate users of marijuana will not return a positive result on a drug test after five to 15 days of abstinence from it. Chronic users may need a month to completely detox. Fluid intake and use of detox drinks can help remove the marijuana from your system.
