6.37 lbs = 2.9 kg = 2900 grams

2900 grams x 1,000,000 micrograms/gram = 2,900,000,000 micrograms (mcg)

A "hit" of acid runs anywhere from 50 to 250 mcg (or so I've been told.) Lets make it a good hit or 290 mcg just to make the math easier...

2,900,000,000 mcg / 290 mcg per hit = 10,000,000 hits.

Nobody smart enough to make LSD (and it is not easy to make) would keep that many hits in one pile (too many eggs in one basket if you know what I mean,) so it's probably not pure LSD - might be blotter acid where they are including the weight of the paper in the total weight which would change the calculations by a lot. Still, it's way more than enough for a good party!

“might be blotter acid”

According to a friend, back in the ol’ days blotter would have you staring in a mirror for 30 minutes (and other crazy things).

Kid Charlemagne could!
