We're not talking about people having underlying mental issues being bought out by weed, although that in itself is a fact even you can't deny, and it still pertains to this current conversation even though it wasn't mentioned. No, what we're talking about are those lazy 420blazeit kunts that sit around all day smoking weed and not doing anything productive with their lives. You cannot deny the existence of this people, you cannot deny that it is ruining their lives. All their potential out the window because they would rather get high all day. All substances can cause this; it's not restricted to weed only, but you're kidding yourself if you deny this happens/think it isn't a big deal
