As well as the original doves, Mitsubishis, Mercedes et al from the 90s, one that distinctly stands out for me was Pink Calis from 1998/1999. Small pink crumbly pills with just a score line on one side and no stamp. They seemed too small to include a decent dose of MDMA so fuck knows what they were. But they were probably the trippiest pills I've ever had. Imagine the visuals of psilocybin combined with the confidence and sociability of fuckin good amphetamine. Never had anything like it before or since.
I was on a college field trip in Scotland and we were sat in a pub drinking, all fucked on these pills, and my mates were growing fractal images of their faces from their heads. I looked at the bar and saw a beautiful sunset behind like we were sat in a beach bar in Hawaii or somewhere.
Got back to the hostel where we were staying and must have fallen asleep with a spliff in one hand and a Mars bar in the other because the next morning I woke up to a massive burn hole in the duvet cover surrounded by molten chocolate...
Anyway, I'm struggling to find anyone else that remembers these.
