Still, there are differences between addiction and having a bad habit or being a functioning addict.
Not many people can hide an alcohol addiction well, but there are many people who self medicate with a variety drugs that you’d never have guessed. There is a reason the black market in drugs is so profitable and it’s not because of a few loser addicts that ruin their own and others lives, shit loads of people that you’d never have suspected are regularly taking this or that drug.
If someone smokes weed as a coping mechanism, but they can function normally, hold down a job and a relationship and everything else, then power to them.
Your point is valid, but you would be shocked at how many alcoholics can function and appear normal.
Believe me, I know.
The problem is that a functional alcoholic is still completely disassociated from reality when heavily drunk, you just can’t recognize it from their behavior.
