Doing a bit of research, it has led me to believe that Tryptamines wouldn't be tested for in most drug tests given that they are found in trace amounts in the body and are available in many plants, even without making you trip, could this be the reason why (I have friends who get tested, their sheets do not indicate testing for Tryptamines) they arn't tested for? Ofcourse there's that possibility they are tested for and you arn't shown, then that's illegal however.
Anyone educated on the subject got two cents?
