I've got grips on some new 'cid in Calgary, AB.
Apparently it's kind of old, but has been stored very well.
It's a really psychedelic painting drawn across the sheet with a small strip of white on the top ten strip.
Some people have reported it as feeling much like Green Alien Heads that went around a few months back.
It has a metallic taste, and takes around 2+ hours to start tripping, but first effects are felt within 30 minutes. The trip itself is very consistent with LSD, but there is a little vasoconstriction that several people noticed. - I would say it is a Do-'x' but the trip duration doesn't seem to match, and neither does the patterning.
A few rumors started about this being the famed 'Orange sunshine' acid from the 60s, or ALD-52.
It seems like really rare blotter, and is definitely odd in my two experiences at 2 and 3 hits.
