Ok I have smoked about 3 bowls and half a J in 3 weeks and I think this will show up on a drug test and this isn't the first time I have smoked I have smoked about 10 other times just not a recent. What is the best way to get all of it out of my systeme before like 2 more weeks? my friend sais he has a pill to sell me that will do it. is this true? really need to know!!!!
