MKULTRA was real enough, her story I don't know. As far as I know it was from unsworn testimony and is well outside of areas I normally spend much time on so it's hard to say what parts are real and what aren't. The real parts were questionable enough to lend some doubt I guess.

The main reason I'm aware of the subject at all is that it brushed across drug reform as well, the Schaffer Library of Drug Policy has a collection of info based on the joint hearing before the Senate Select Committee on Intelligence in '77. I don't know if she is mentioned but it should be good background on the subject in general.

thanks for the audio pyrex. That's some LOL stuff

Here is some info on the toxicity of THC:

http://en.wikipedia.org/wiki/Tetrahydrocannabinol#Toxicity
According to the Merck Index, 12th edition, THC has a LD50 value of 1270 mg/kg (male rats) and 730 mg/kg (female rats) administered orally dissolved in sesame oil.[2]

If this were scaled up to an adult human, the LD50 would be between approximately 50 and 86 g for a 68 kg (150 lb) female or male person respectively. This would be equivalent to 1-1.8 kg of cannabis with a 5% THC content (roughly average) taken orally.

In summary, enormous doses of Delta 9 THC, All THC and concentrated marihuana extract ingested by mouth were unable to produce death or organ pathology in large mammals but did produce fatalities in smaller rodents due to profound central nervous system depression.

The non-fatal consumption of 3000 mg/kg A THC by the dog and monkey would be comparable to a 154-pound human eating approximately 46 pounds (21 kilograms) of 1%-marihuana or 10 pounds of 5% hashish at one time. In addition, 92 mg/kg THC intravenously produced no fatalities in monkeys. These doses would be comparable to a 154-pound human smoking at one time almost three pounds (1.28 kg) of 1%-marihuana or 250,000 times the usual smoked dose and over a million times the minimal effective dose assuming 50% destruction of the THC by smoking.

Thus, evidence from animal studies and human case reports appears to indicate that the ratio of lethal dose to effective dose is quite large. This ratio is much more favorable than that of many other common psychoactive agents including alcohol and barbiturates (Phillips et al. 1971, Brill et al. 1970).
