"Pot makes people peaceful and happy through its effects. There would be no war or fighting if everybody smoked pot."
No. Maybe you, but that doesn't go for everybody. If you think it's impossible to create violence between marijuana users you're a noob. It does not incite aggression, but it's not necessarily sure to stop it.

"Pot makes music sound better!"
Not all the time. Try listening to Twiztid or ICP high, and I guarantee they will continue to suck either way.
