That sucks don't smoke at home. Don't come home till your not stoned. If that ain't going to work get some eyedrops and get into the spirit of pot don't worry. Your greatest enemy in avoiding capture is paranoia which is a self propagating symptom. Don't get in the habbit of freaking out. Just be cool. When I say be cool I mean don't freak out. Take some extra precuations don't go home smelling like a drug den Get home on time or call,becuase if your late your parents are already suspicious. Hell you might just quit untill your dad gets out of "cop mode". But at the same time talk to them about pot all the time benefits.
