Here's the thing about drug use that isn't taught:

People use it to cope.
Most of that coping is from harm caused by the general public.

Coping from the general public, requires not dealing with the general public.

Drugs have a quick effect
Are accessible
Can be done at home

There's few cooing mechanisms that take up less space.

Fewer that have the same nigh instant effect

That's part of the issue. When you are charging more for space, there's less space to relax after work. Since wages have been stagnant since the early 80s

"Go to the gym"
-there's people at the gym

"Go for a hike"
-need a car, not always available

"Travel"
-stagnant wages since the 80s with ever growing coat of living

"Beans and rice"
-see previous point

So much "self help" fails to understand this abuse avoidance relationship
