I don't know if this applies, but the first time I tried mescaline I consumed 60g worth of resin, and at about t+8:00, I snorted some re'Xed 2C-e. I'd imagine 15-20mg, whatever was stuck to the inside of my bag.
Not only did this not burn, but I have full on OEV's within 1 minute. Both being PEA's, I'm sure there's some type of cross-tolerence, but together, I think they compliment each other.
