I need facts for a presentation on the long term effects of pot smoking?

One website I would strongly recommend is Erowid.com

Try this link below. It has a lot of the facts without being weighed down with the "Marijuana is EVIL!" propoganda that the government spews on a regular basis. The short answer is that it's still way healthier than cigarettes or alcohol, but some of the details of the health problems it does present are outlined in the article. Hope that helps! ^_^

You can find the full text of the major government commission reports on the subject at http://druglibrary.org/schaffer/Library/studies/st...

The largest study of the long-term health effects was done by Kaiser Permanente. They surveyed the records of 65,000 patients over many years. They found no significant differences in the health records of those who smoked pot versus those who didn't. You can find that report at http://druglibrary.org/crl/aging/sidney-01.html

Number of American deaths per year that result directly or primarily from the following selected causes nationwide, according to World Almanacs, Life Insurance Actuarial (death) Rates, and the last 20 years of U.S. Surgeon Generals' reports.

TOBACCO 340,000 to 450,000

ALCOHOL (Not including 50% of all highway deaths and 65% of all murders) 150,000+

ASPIRIN (Including deliberate overdose) 180 to 1,000+

CAFFEINE (From stress, ulcers, and triggering irregular heartbeats, etc.) 1,000 to 10,000

"LEGAL" DRUG OVERDOSE (Deliberate or accidental) from legal, prescribed or patent medicines and/or mixing with alcohol - e.g. Valium/alcohol 14,000 to 27,000

ILLICIT DRUG OVERDOSE (Deliberate or accidental) from all illegal drugs. 3,800 to 5,200

MARIJUANA 0

(Marijuana users also have the same or lower incidence of murders and highway deaths and accidents than the general non-marijuana using population as a whole. Crancer Study, UCLA; U.S. Funded ($6 million), First & Second Jamaican Studies, 1968 to 1974; Costa Rican Studies, 1980 to 1982; et al. LOWEST TOXICITY 100% of the studies done at dozens of American universities and research facilities show pot toxicity does not exist. Medical history does not record anyone dying from an overdose of marijuana (UCLA, Harvard, Temple, etc.).

to quote george carlin " the only reason that marijana has not been legalized yet is that everybody keeps forgetting where they put all the petitions" does this answer you're question ,or have you forgotten the question already ?

(I couldn't resist posting this. In my observation, pot is significantly less harmful than alcohol and cigarettes on people's health and on the well-being of the people around them. This is not exactly what you were looking for... sorry.)

hmmm, well marijuana effects the memory...that's all I remember.

You have the world at your findertips.....Google it.
