Perhaps, if our main goal is to simply reduce consumption of a specific drug. The problem I see is that problem avoidance finds other paths. Get rid of heroine? People will use marijuana. Marijuana gone? People use alcohol. Alcohol gone? People use video games.

I don't think the drugs are inherently the problem, as there's a paper I loved talking about different kinds of escapism: one where people escape to avoid problems and the second where people escape to solve problems.

So I still think the root is problem avoidance, which at an even more root level is emotional avoidance, especially of "bad" feelings, mostly sadness.

So I don't see it as self-actualization for some noble goal, but rather a practical how do I actually solve problems in my life goal.

tldr; banning certain drugs can be whack-a-mole, trying to solve symptoms but not the problem.
