Obviously this is highly anecdotal, but for the 5 years that I lived in Spain, I was a regular drug user.

With the exception made of MDMA & speed (That I'll consume both on occasions) I was consuming weed, hash and mushrooms on a weekly basis.

And everybody on a certain group of friends was doing the same. We had a surplus of mushrooms, as we had somebody in our group (A neurobiologist) growing them.

13 years ago I came back to Argentina, and then stopped consuming cold turkey.
