5 days: The half life of marijuana is is variable with a mean value of between 13-20 hours. It takes approximately 6 half lives for a drug to be eliminated from your system. 20*6/24=5 days. The marijuana will stay in your system for about 5 days. Marijuana can also stay in your hair for up to 30 days.
