couldn't be that he was just a crazy fucker....i make and smoke hash, i make and eat edibles, and its never made me want to kill anyone. when i don't have any, i occasionally get the urge, but have been able to suppress it so far.
i look at this as bullshit, but even if it had a small amount of legitimacy, its still your responsibility to not consume something that you know has a bad effect on you. i don't use amphetamines or barbiturates, because they have a bad effect on me. same with opiates. i use cannabis because it has no bad effect on me that i've ever been able to perceive. if you're one of the unfortunate few that can't handle it, then QUIT FUCKING IT UP FOR EVERYONE ELSE you fuck. and if you're just a batshit crazy fucker to begin with, quit trying to blame my drug of choice for your fucked up behavior
