I am 19 and what are these consequences you speak of?
there are none. he doesn't really know what's he's talkin about. THC never made victims. Alchool, methamphetaminics, cocaine, opium related (eroine), various chemicals, cocaine treated crystals (crack) made victims. but THC related (grass, hashish, etc) never made as far as i know. my uncle is 58 years old, he's an architect and never had an issue so far.
