I've written to my Member of Parliament in support of studying drugs and
prostitution around the world, with a view to decriminalising and regulating
them. The aim, here, is to create a system with proper health and social
checks and balances with a view to encouraging progression.

I think, the general approach with self-improvement and societies wellbeing
can leverage the same tools. Indeed, as the government has already done in
its approach to gambling, top quality regulation and effort in education and
family policies can work towards a better overall end.

As for the specifics of drugs and Buddhism, I'd say they can but don't
necessarily go with each other. The dangers of going down a wrong path or
worsening a mental health condition are issues. Going for a walk or spending
time with other people may be more useful.
