This is something I've been wondering about for a while.... I've often heard people say that the way mescaline builds tolerance is a little different to many other psychedelics. But I didn't really know what a possible reason for it could be until I read this:
http://www.ncbi.nlm.nih.gov/pubmed/1969270
Mescaline doesn't effect binding to 5-HT2A receptors. This is the same case as for DMT. That definitely seems like a potential factor, right?
What's interesting is that I've heard people say that you can take mescaline for days without tolerance, which fits with this and with how DMT works, but I've also heard people say that taking it before another psychedelic produces tolerance to that, but taking it after still allows for a full mescaline effect. That's the exact opposite of how I would expect DMT to work!
So, I'm curious... does anyone here have experience using mescaline in close proximity to other psychedelics, before or after? If so, what did you find in relation to tolerance? I'm not looking for "oh, anything that binds to 5-HT2A should produce cross-tolerance" answers here, I want real anecdotes!

Lysergic acid diethylamide (LSD) administration selectively downregulates serotonin2 receptors in rat brain. said:A dosage regimen of lysergic acid diethylamide (LSD) that reliably produces behavioral tolerance in rats was evaluated for effects on neurotransmitter receptor binding in rat brain using a variety of radioligands selective for amine receptor subtypes. Daily administration of LSD [130 micrograms/kg (0.27 mumol/kg) intraperitoneally (IP)] for 5 days produced a decrease in serotonin2 (5-hydroxytryptamine2, 5-HT2) binding in cortex (measured 24 hours after the last drug administration) but did not affect binding to other receptor systems (5-HT1A, 5-HT1B, beta-adrenergic, alpha 1- or alpha 2-adrenergic, D2-dopaminergic) or to a recognition site for 5-HT uptake. The decrease was evident within 3 days of LSD administration but was not demonstrable after the first LSD dose. Following 5 days of LSD administration the decrease was still present 48 hours, but not 96 hours, after the last administration. The indole hallucinogen psilocybin [1.0 mg/kg (3.5 mumol/kg) for 8 days] also produced a significant decrease in 5HT2 binding, but neither the nonhallucinogenic analog bromo-LSD [1.3 mg/kg (2.4 mumol/kg) for 5 days] nor mescaline [10 mg/kg (40.3 mumol/kg) for 5 or 10 days] affected 5-HT2 binding. These observations suggest that LSD and other indole hallucinogens may act as 5-HT2 agonists at postsynaptic 5-HT2 receptors. Decreased 5-HT2 binding strikingly parallels the development and loss of behavioral tolerance seen with repeated LSD administration, but the decreased binding per se cannot explain the gamut of behavioral tolerance and cross-tolerance phenomena among the indole and phenylethylamine hallucinogens.
