um..
check research. cross-tolerance develops for hallucinogens. if you take a hit of acid, id wait a few weeks or so if you want to trip off of one. i got some really good AZ acid a few months ago and it was awesome. a few weeks ago i took another hit and got some decent visuals but a strong body high from it. then i took another hit a few days later (about 5 days) and i got very little visuals (tolerance rising). then i took 3 hits about 2 days after that and tripped balls. then the next day i went to a 9 hour rave and dropped 5 hits. tripped harder than i ever have on anything in my life. was truly an amazing night.
edit: oh and, the last 9 hits i took was GOOD acid. not shit.
also, whats a 'strip' to you? most common 'strips' are 10 hit strips. i get them for about $65.
from what i've seen acid usually goes for anywhere between $6-$9/hit nowadays. (ive heard of a few people selling for $10...ripoff imo)
have fun, and be careful. acid can rewrite your personality. it's happened to me. but i just fixed it with more acid!
just make sure you're having a fun time when you trip and you're all set.
