weed is out in a month that is the golden rule. If you are drinking a pissload of water it's more like 2-3 weeks but why take the chance? Cocaine is 3 days and that's all I know on the subject.
rhino44 Reviewed by rhino44 on . WHAT GETS OUT OF YOUR SYSTEM QUICKER? Shrooms or Weed? I've heard Weed can stay in your system up to 6 weeks. (for heavy smokers). but i know light smokers who have passed drug tests when they smoked weed three days before the test just by drinking a lot of water. I've heard Shrooms stays in your system for a maximum 8 days. But i need facts. Say if you did both in moderation which one would be out of your system quicker? Rating: 5
