[astroglide]

lsd is not addictive and by its nature it doesn't lend itself to 'benders'. tolerance develops intensely fast and makes it so that it's a practical difficulty to string multiple sessions/days together (and users will normally never find themselves even wanting to do this). it's also about $5 per dose and lasts 6-12 hours, so it's certainly not going to put somebody in the poorhouse.

in drug speak dots are microdots, a tiny pill-like form of (usually) lsd.

the only way to physically tell if somebody's on it is to look at their eyes. if they're tripping, their pupils will be seriously dilated.

you should be able to find everything you want/need by reading at erowid and wikipedia.
