Cards on the table? I'm a Buddhist. I think psychedelics present one avenue toward alleviating existential suffering, in universal (i.e. spiritual) and particular (i.e. medical) forms. I think that if an individual uses proper intentional techniques with psychedelics, it is more likely that both of these aims will be achieved in a deeper way than taking these substances without technique.

For particular global problems, such as creating global regulations to protect the environment, nuclear disarmament, etc., I think more efficient systems of democratic governance are a more likely solution than meditation or psychedelics. I do think psychedelics and meditation and related things can solve pretty deep and perhaps universal issues for individuals, I'm just not sure if they're helpful for global issues like climate change and others. I think on that front their impact is fairly minor. A guy like Bernie Sanders seems like a more direct route to effecting that sort of change, by doing things like taking money out of politics and thereby achieving a more efficient democratic system.

I could be underestimating their impact though. Nick Sand said he had no idea how psychedelics could save the world in an interview I saw once, but he did firmly believe they could and perhaps even already had. He thought distribution of psychedelics may have prevented nuclear war years ago. Maybe he was right.
