hay, i started smokin at 12 and im not criminally insane, and for the brother finding out that you smoke pot, well, if there is a confrontation with your parents about it...simply say "im sorry but thats your problem if you have a problem with me smoking, not mine", they will take that as a mature, sensible thing to say and say "yes son, your right...heres $100, go out and buy a nice big bag"...and its all good!!!
