Thanks for your question.
The research could be funded that gets a magic bullet to help address methamphetamine addiction, but I think billions of dollars have already been spent in the U.S. to that end, in particular, to no avail. As I said earlier on, it's quite different from opioids, as your comment implied, so I don't think the answer to this crisis is going to be through finding some magical medication that helps people stop using. There are some drugs, like anti-depressants, Prozac and others that will help reduce cravings in some people, but there are not a lot of drugs.... I think it's unlikely we're going to find one that solves the problem that way.
