Counterpoint: Most of the people I know who picked up drug addictions (all who have received treatment and currently recovered) picked them up from social situations. They encountered groups where drug use was their common weekend activity and you either joined them or you weren’t included.
Being in between jobs or having a job with low demands was also an enabler of drug addiction. Idle hands and all that.
> Just having a social life will not only keep you addiction-free but also enables you to use the same substances recreationally in a healthy way
This generalization doesn’t hold at all. I haven’t heard of any addicts who became more moderate of their use of hard drugs when surrounded by other users of those hard drugs. The correlation goes the other way. Being around other users both enables and encourages more drug use.
