You are right with your observations.
The root cause are mental health disorders like depression.
There is no fast working anti-depressant like alcohol.
People try to solve their problems in the short path with it, it works, but in the long run, the problems coming back even more severe.
Untreated disorders will be amplified like abuse, depression etc.
But its understandable people try alcohol first, until therapy and medication works, its a hard time.
