I don't know how common that kind of usage is. This was a group of people I hung with back in the 90's.

The dangers of riding a horse are immediately apparent and it's easy to link cause and effect. Additionally the damage from a bad horse ride (unless you hit your head) are more likely to be physical trauma, a broken leg etc.

The (possible) negative effects of a drug on cognition are more subtle and harder to attribute.

Again, I'm not anti drug at all (especially legally speaking).

It's just, what I saw and I feel I should relate it as a bit of a cautionary tale. I am convinced overuse of MDMA has a negative effects on the kind of cognition that allows a person to plan, link cause and effect, think abstractly and that kind of thing. It's not a scientific study, just what I believe from observation.
