Title: LSD/Psilocybin Cross-Tolerance Question
Post by: phangka on July 25, 2012, 02:09 am
I took a large dose of LSD on Sunday, around 600ug.  Today my friend called and asked me to drive him to a music festival a few hundred miles away.  He's offered a free ticket, gas money, and an eighth of cubes.  There's no way I am turning him down.


Question is, what kind of effects can I expect from an eighth after taking such a large dose of LSD 5 days prior?

My rule of thumb is after one week you need about 20% extra for a similar experience, and after two weeks you can dose the same again. If you tried dosing the next day it would be more like an extra 100% or more. Admittedly the experience I'm quoting here is LSD to LSD, not LSD to Psilocybin. If you assume that the cross tolerance will be roughly the same (it's likely less in actual fact, but I'm thinking worst case scenario here) then I would say you'll lose about 30% of what you would have had with no tolerance.

Everyone is different though, so this is a really rough estimate and probably won't mean shit for you :P If the cubes are free though I'd just go with it and let the experience be what it wants to be :)

after 5 days, you will still have a slight tolerance. 7+ days brings your tolerance back to baseline.

You want to be safe and potentially not waste drugs? Don't take psychedelics within 7 days of each other. That includes LSD, Shrooms, DOB, etc. They all have cross-tolerance. Usually 2 days between trips is good for me, I've got a pretty decent metabolism and drink a shit ton of water and OJ. My friends have to wait at least 7 days to get back to baseline though.
