alcohol only negatively effects one person

Tell that to the hundreds of thousands dead due to drunk driving, or the many women and children who suffer domestic abuse from alcoholics.

Alcohol is one of , if not the worst drugs for society because it can cause belligerence which can lead to violence, and it lowers inhibitions and cognitive capabilities causing people to do dangerous shit and failing horrifically and harming people like drunk driving.

In moderation has almost no negative effects

there is no safe level of alcohol consumption it is poison, and I say that as someone who drinks often.
