Q: I have read somewhere that 1200mg of mescaline can be deadly for humans (respiratory depression, liver damage), which would be three times the amount you need to have a strong trip. Is that true?

A: Any substance can be deadly in high enough quantities, even water. That being said, mescaline is one of the safest drugs known. There have been no verified human deaths from mescaline ever, although K. Trout states that there is one unconfirmed (and unconfirmable) report of a person who died during military experiments with the drug, after receiving a 15 gram dose intravenously (or about 150-200mg/kg).



In experiments with rats, the LD50 for mescaline has been established in the range of 800-1200mg/kg orally.



Considering the human dose of mescaline is around 200-500mg orally, this means you would have to try very hard to take a fatal dose. It would be extremely unlikely to happen accidentally.
