From the Erowid:
---------------------------------------------
"The LD50's for mescaline, MDA and MDMA were determined by intravenous [15] or intraperitoneal [16] administration in five species of animals. MDMA had LD50's between 2 and 6 times less than those of mescaline and between 1.5 and 3 times more than MDA. This means that MDMA is more lethal than mescaline but less lethal than MDA.
29. Intraperitoneal LD50's for MDA and MDMA were determined in mice by Davis. The LD50's of MDMA and MDA were substantially the same with the LD50 for MDA equaling 90.0 mg./kg. and the LD50 for MDMA equaling 106.5 mg./kg.

---------------------------------------------
An excerpt from Pihkal # 100 states a rather unusual case of MDA overdose (I hope anyway):
---------------------------------------------
" There was one case in 1953, involving MDA and a psychiatric patient named Howard Blauer that proved fatal. The army had contracted with several physicians at the New York State Psychiatric Institute to explore new chemicals from the Edgewood Arsenal and one of these, with a chemical warfare code number of EA-1298, was MDA. The last and lethal injection into Blauer was an intravenous dose of 500 milligrams. "
---------------------------------------------
Pity the determined cause of death is not mentioned i.e. heart, renal, hepatic failure etc.
Whilst intravenuos administration would produce more toxic effects (and quickly), and with oral administration you would probably eliminate much before such levels were reached in the bloodstream, you could perhaps produce similar effects if you ate enough, after all 500mg is only 4 good E's. In guessing that 10 x the amount orally is enought to kill, then 40 good pills should do the trick. Any comments?
