I think this might be highly dependent on your social circles. As an extroverted 35 year old single man living in Europe, who doesn't drink alcohol, it seems like approximately 80% of my social circles have done psychedelics.
That's funny. I have met exactly one person who I know is a Taylor Swift fan. That is much less than the number of people who I know have taken psychedelics.
I have a similar gripe. I know a few more people who have done psychedelics, but still it's tiny compared to the number of people I know who have talked about using marijuana.
As a late 30’s trans woman working in tech and living in Oakland all of my friends do psychedelics.
