Just fyi... in case nobody has noticed, his stated location is India. This is why I've refrained from replying. I don't know much about Indian culture, so maybe I'm wrong, but from the little I know, I think parents are much more strict, and have greater expectations from their children than we generally expect in the West.
Telling your Indian parents you smoke pot is probably 50 times harder than telling your Western parents you smoke pot. In the West, it wouldn't really be a big deal, whereas over there it's probably more along the lines of, "how could you possibly do this to the family, after everything we've done for you?"
Just saying...
