In any electro party in any western european, ~ 25% people at least regularly take either c, d, l or k... most of us pretty reasonably.
Meanwhile an insane proportion of engineer are downright alcoolics...
"Drugs" is not a thing. Only addiction is, and in a few years, a few of them will be legalised for (rare) medicinal purposes. Especially MDMA.
Stay safe (harm reduction first) but dont be scared to experiment at all.
