1. 大麻是放松剂,不induce暴力
marijuana (grass, pot, weed) is a type of downer, which means that who's under the influence will think and reflex slower, thus will be very relaxed, and may laugh more easily. but at the same time the influence makes it hard for drivers to respond to sudden, unexpected events
2.大麻致瘾度极低,远低于香烟和酒精类饮料
it is not as addictive as cigarettes or alcohol, indeed, it is not physiologically addictive. Users can quit without physical illness. But long term users can be addicted emotionally (psychologically).
3.大麻有非常好的止痛和放松的医用效果,对人体的伤害(if any)远远小于香烟和酒精(后两种原也是禁用品)。Many food products may have adverse effects to our health, for example, 花椒还真是禁品,兴奋和致瘾效果满大
4.很少吸食者一次大剂量使用,多只吸一两口over a fairly long period of time, you won't even notice if you don't know
it's too hard to type chinese now, sorry...
