"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."
c = cocaine
d = dmt? heroin?
l = lsd?
k = ketamine?
What about MDMA (aka ecstasy or molly -- though often what users get under those names is actually not MDMA but other drugs, leading to fatalities) ?
And why even abbreviate the names of these substances?
