the LD50 (Lethal Dose*) of lsd varies depending on where you are seeing...some site such as erowid say 12,000 ug but you can find higher online. There is that one death of a guy who had like 340000 injected in himJ2012B said:sorry, what?
plenty of people have eaten well over this amount and come back just fine ... as far as i know there is no risk of a physical overdose anywhere near this range.
wow... this thread is just overflowing with bullshit

"For example, the LD50 of LSD is 46 mg/kg intravenously in mice -- compare to an active dosage of .001 mg/kg (1 microgram/kg) in humans."
While I am sure IS possible to live after taking 20000 mics, we are talking about a dosage equal to 200 regular good acid hits. Very few have ever taken this much at once, or would want too. If it didn't kill you and leave you with permanent effects..I guess it would be a hell of an experience to describe.
