yeah, you probably shouldn't tell them. my parents kind of suspected i smoked and so i admitted it to them, and then followed up with a "but i'm trying to quit" (i wasn't really but i thought it would get them off my back). my dad was like, "well i could ground you but that won't help and you're trying to quit anyway" but my mom flipped out and searched my room, and found my new bowl, ashes, and an emptie baggie that smelled heavily of pot. long story short, they even started drug testing me for awhile. then again, my parents are very conservative christians who believe in family values and think that mtv is the channel of satan, so it kind of depends on your parents... if they're laid back and open minded you have a much better chance of gaining their acceptance
