Tell them. But be mature about and and explain to them that you're able to function and still deal with everyday life with it. Tell them that if you're ever caught, you'll take responsibility. Also, emphasize that it won't effect your schooling (if it will, then don't bother lying). Oh, and make sure that they know it won't lead to other drugs or alcohol, parents worry about that more than anything.

Then ask them if they wanna smoke up with you.:thumbsup:
