Up to few more days: Thc, the psychoactive ingredient in marijuana, has a half-life of 2-10 days depending on the amount smoked. If the half-life is 3 days that means it will take 3 days for half of it to leave your system & 6 days for 3/4 of it to be eliminated. Despite this most people only feel effects for several hours after smoking. The effects will lessen day by day. Sounds like this is not a good herb for you.
