2. thumb print
a way of taking A LOT of acid. the 'cid is dissolved into a greasy substance at high concentration, and stored in a lip balm container. to dose, stick your thumb in, smear out enough to coat it, and lick it off. depending on the quality of the stuff and how much you scoop out, it seems to be the equivalent of anywhere from 5 to 20 blotter hits.
the first time you do acid, don't do a thumb print. you should work up to that dose in a few sessions with experienced friends.

1. Thumb Print
10,000 doses of LSD; that is, 10 Bibles, or 100 sheets. Few people ever possess an entire thumb print of LSD, only acid Chemists and distributors.

There are stories about people pressing their thumb against LSD crystal, or taking large doses by saturating one's thumb, but these are probably myth.

About 10,000 doses of LSD can fit on the tip of one's thumb.
A thumb print sold by individual doses is worth a $100,000 USD, at $10/dose
