| What is the lethal dose of marijuana? | |
| According
to which US Government authority you want to believe, the lethal dose
of marijuana is either about one-third your body weight, or about 1,500
pounds, consumed all at once. 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). Acute Effects of Marihuana, from Marihuana, A Signal of Misunderstanding - Table of Contents 4. Nearly all medicines have toxic, potentially lethal effects. But marijuana is not such a substance. There is no record in the extensive medical literature describing a proven, documented cannabis-induced fatality. 5. This is a remarkable statement. First, the record on marijuana encompasses 5,000 years of human experience. Second, marijuana is now used daily by enormous numbers of people throughout the world. Estimates suggest that from twenty million to fifty million Americans routinely, albeit illegally, smoke marijuana without the benefit of direct medical supervision. Yet, despite this long history of use and the extraordinarily high numbers of social smokers, there are simply no credible medical reports to suggest that consuming marijuana has caused a single death. 6. By contrast aspirin, a commonly used, over-the-counter medicine, causes hundreds of deaths each year. 7. Drugs used in medicine are routinely given what is called an LD-50. The LD-50 rating indicates at what dosage fifty percent of test animals receiving a drug will die as a result of drug induced toxicity. A number of researchers have attempted to determine marijuana's LD-50 rating in test animals, without success. Simply stated, researchers have been unable to give animals enough marijuana to induce death. 8. At present it is estimated that marijuana's LD-50 is around 1:20,000 or 1:40,000. In layman terms this means that in order to induce death a marijuana smoker would have to consume 20,000 to 40,000 times as much marijuana as is contained in one marijuana cigarette. NIDA-supplied marijuana cigarettes weigh approximately .9 grams. A smoker would theoretically have to consume nearly 1,500 pounds of marijuana within about fifteen minutes to induce a lethal response. 9. In practical terms, marijuana cannot induce a lethal response as a result of drug-related toxicity. 10. Another common medical way to determine drug safety is called the therapeutic ratio. This ratio defines the difference between a therapeutically effective dose and a dose which is capable of inducing adverse effects. 11. A commonly used over-the-counter product like aspirin has a therapeutic ratio of around 1:20. Two aspirins are the recommended dose for adult patients. Twenty times this dose, forty aspirins, may cause a lethal reaction in some patients, and will almost certainly cause gross injury to the digestive system, including extensive internal bleeding. 12. The therapeutic ratio for prescribed drugs is commonly around 1:10 or lower. Valium, a commonly used prescriptive drug, may cause very serious biological damage if patients use ten times the recommended (therapeutic) dose. 13. There are, of course, prescriptive drugs which have much lower therapeutic ratios. Many of the drugs used to treat patients with cancer, glaucoma and multiple sclerosis are highly toxic. The therapeutic ratio of some of the drugs used in antineoplastic therapies, for example, are regarded as extremely toxic poisons with therapeutic ratios that may fall below 1:1.5. These drugs also have very low LD-50 ratios and can result in toxic, even lethal reactions, while being properly employed. 14. By contrast, marijuana's therapeutic ratio, like its LD-50, is impossible to quantify because it is so high. 15. In strict medical terms marijuana is far safer than many foods we commonly consume. For example, eating ten raw potatoes can result in a toxic response. By comparison, it is physically impossible to eat enough marijuana to induce death. 16. Marijuana, in its natural form, is one of the safest therapeutically active substances known to man. By any measure of rational analysis marijuana can be safely used within a supervised routine of medical care. |

Can't Talk: It's not the drugs, and it's not senility. by Inland Thu Aug 24, 2006 at 07:00:43 PM PDT |

| Bush's
press conferences and unscripted remarks are so painfully bad, it spurs
the question: what is his PROBLEM? People have remarked that he wasn't that way when he was the Governor of Texas, and therefore theorize that he has deteriorated due to premature senility or a lifetime of drug use. I think the reason George Bush stumbles, ends sentences midway through to jump to another thought, rattles off non-sequiturs, and makes up words, is that George Bush is breaking under the strain of lying almost all the time about almost everything. I think it's because lying is hard work, and he's trying to hold several different false scenarios in his head while not blurting out what he's really being told behind closed doors. Bush looks like a person stumbling over the easiest things, but in fact, he's not a person unable to relate simple facts. He's a person trying hard to NOT relate simple facts. He's a person trying to avoid the pitfalls of saying what's on his mind, and trying to keep his stories straight. As I lawyer, I see people trying to construct false scenarios all the time. But you don't remember lies the way you remember truth. It's easier to remember, e.g., how fast you were driving than it is to remember the exact lie you told the police officer about how fast you were driving. People who lie have to put a lot of energy into keeping their lies consistent with each other and, well, consistent with undeniable facts. My grand theory is that Bush's entire presidency, from the beginnings of his campaign until now, is based on his taking public stances that at least obscures goals and positions shared secretly. He and his Roves have always accepted that the majority of the country wouldn't want him if they knew the promises he made to the right wing Christians and the rich, if they knew the actual effect of his tax cuts, if they knew the evidence behind environmental damage, and on and on. Now, he's hiding the entire foreign policy fiasco(s), who is being held by him incognito, who is being spied upon, what he knew before 9/11, and on and on and on. If you had so much to hide, you too would only use canned speeches, carefully vetted by speechwriters who don't know the real story anyway, to keep it all straight, and you would stumble and hem and haw in all other circumstances. Which explains why his problem wasn't so evident as Texas Governor. Bush's brand of crony capitalism and piestic Christianity went down well in Austin, at least for a governor with no real constitutional authority: Bush only had to repackage himself for the national race, essentially submerge his real persona and his real ideas and his real goals and pretend to a compassionate, not-asshole conservativism. You know how they tell you, on a date, just be yourself? And how you think, no, I don't want her to meet that guy just yet? Well, Bush and Rove have been saying that for six years, and Bush has been schizo, trying to send signals and winks and nods to his fundamentalist Christians and send money to his corporate sponsors while slinging a load of bull at the nation. Add to that all the bodies he has to keep buried, and you've got a guy who is in a state of flop sweat every time he has to open his mouth in public. Bush isn't senile, or drug addled. He's a lying asshole. And it's hard work. Only truly gifted and intelligent sociopaths like Rove and Cheney can rattle it off. Bush can't. |
