What evidence is there of meth not being super addictive and life destroying? The person you're replying to misread the statistic, which was actually 7% (not one-in-seven).
This study claims that there are 7.3 heavy meth users per 1000 15-49 year olds in Australia. Meaning 1 in 10 people who try meth become a heavy user. That seems like a lot to me, given the lifestyle heavy-users live.
According to this study, only 10% of heavy drinkers are alcoholics. Obviously heavy drinkers are a small portion of total drinkers, so your 10% number is way off base. Even if it was correct, two wrongs don’t make a right.
