Answer to your Question

Answered By: Addiction Specialist

Answer: According to one study, 46% of heavy marijuana users experience withdrawal symptoms when they stop using. These symptoms can include agitation, depression, insomnia, nausea, anorexia (loss of appetite), and tremor. About 8% of low-frequency users experience these symptoms when they stop using marijuana. Withdrawal usually begins within 10 hours of the last use, peaks within 48 hours, and goes away after five to seven days. Although withdrawal from marijuana may be uncomfortable, it is not life-threatening and is usually not treated with medications. While the symptoms of withdrawal may subside after a week, the active substances in marijuana and their metabolites may persist in the body and be detected in the urine for much longer, particularly after prolonged, heavy use.
