Study finds smoking marijuana doesn't cause cancer quote: May 26, 2006. 01:00 AM MARC KAUFMAN SPECIAL TO THE STARThe largest study of its kind has unexpectedly concluded that smoking marijuana, even regularly and heavily, does not lead to lung cancer. The new findings "were against our expectations," said Donald Tashkin of the University of California at Los Angeles, a pulmonologist who has studied marijuana for 30 years. "We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use," he said. "What we found instead was no association at all, and even a suggestion of some protective effect." Federal health and drug enforcement officials have widely used Tashkin's previous work on marijuana to make the case that the drug is dangerous. Tashkin said that while he still believes marijuana is potentially harmful, its cancer-causing effects appear to be of less concern than previously thought.

Will youse people never learn!?With all the emphasis on smoking the herb, you play into the hands of the anti-pot crowd. If you want to kill the costly, make-work industry that fighting pot has become, I suggest you talk much more about the many alternatives to smoking the weed and their potential health benefits.

Don't get me wrong, I find stoners quite harmless. I smoked my weight in the stuff a couple of times over not long ago. I just lose interest in stoner conversation pretty quickly these days. Were it a choice between stoners or drunks, I'll take stoners any time. At least they are passive, and unlikely to get aggressive. When I worked on trawlers, there were some boats where the skipper and crew were perpetually stoned, 24/7. Stuff like that can make it difficult to sleep at night, knowing that the boat is being driven by someone who is lost in his reverie. Particularly in January, when the waves are 40 feet tall.

One of the critical factors in smoking related cancers is just how many puffs of the toxic substances a person takes on a regular basis. Ironically, those who live in smog ridden urban centers are probably taking in as much toxic material from combustions vehicles as a 2 pack a day smoker. Tobacco has an addictive component called nicotine that compells the user to light up one after the other during every waking moment. This indicates that the nicotine hit is momentary and demands constant replenishment in order to achieve its 'buzz'. Soking pot would be just as dangerous as tobacco if the user were to smoke it as often and with as much frequency as the tobacco user simply because of the toxic fumes that all combustion causes. Pot on the other hand is not addictive and the THC 'buzz' lasts far far longer than nicotine does thereby requiring far far less ingestion of the toxic chemicals. The THC buzz can last from 1--4 hours depending on the potency and the users sensitivity to THC. While the nicotine buzz only lasts a few minutes and even seconds in some folks. However, the easiest way to avoid the whole smoking issue with pot is to eat it. the buzz from eating THC infused cookies, brownies and even butter will last even longer than smoking it will as well as avoiding all those nasty combustion byproducts. Plus, smoking gives a 'head' or mental buzz while eating it gives both a head AND a body stone that can make sex and other pleasant experiences way more pleasureable and satisfying. As for whether stoners are 'boring', this only applies to the ones that have recently absorbed some THC while the stoners who have not partaken recently are usually very lucid conversationalists with all kinds of cool insights to share. But if the stoner has recently imbibed then the easiest recourse is to take a hit of THC yourself instead of just sitting there being all uptright and judgemental

Not entirely true... Have you ever seen a vaporizer before? (edit to add... I was going to throw a link on here, but the sites it brings up probably aren't the best to be linking here. heh... Do a search for medicinal vaporizer THC) I also get a feeling that part of that cancer causing agents within a cigarette stems from the fiber glass filter. Breathing in even microscopic peices of that cannot be good for the lungs.

Actually THC is well-known to destroy cancerous cells while leaving healthy cells unharmed. Here's an article I wrote in 2002, and links to the references and some original studies can be found here: http://www.cannabisculture.com/news/cancer A study published in the July 2002 edition of the medical journal Blood found that THC and some other cannabinoids produced "programmed cell death" in different varieties of human leukemia and lymphoma cell lines, thereby destroying the cancerous cells but leaving other cells unharmed. This reaffirms results by researchers at Madrid's Complutense University, who destroyed otherwise uncurable brain cancer tumors in rats by injecting them with THC. Their study was published in the March 2000 issue of Nature Medicine. This ground-breaking research received almost no media attention, and has not been pursued as the researchers couldn't get further funding. The lack of funding is typical of how such research is usually not followed up. For example, a 1974 study by researchers at the Medical College of Virginia, funded by the US National Institute of Health, found that THC slowed the growth of lung cancer, breast cancer and virus-induced leukemia in rats. The 1974 study, titled "Antineoplastic activity of cannabinoids," appeared in a 1975 edition of the Journal of the National Cancer Institute. Yet despite their promising results, no further research was made, and the study has essentially disappeared from the scientific literature. Similarly, a 1994 study, which documented that THC may protect against malignant cancers, was also buried by the US government. The $2 million study, funded by the US Department of Health and Human Services' national toxicology program, sought to show that large doses of THC produced cancer. Instead, researchers found that massive doses of THC retarded certain types of stomach cancer in rats. The rats given THC lived longer than their non-exposed counterparts. The study was unpublished and the results hidden for almost three years, until it was leaked to AIDS Treatment News in 1997, and the Boston Globe broke the story days later. A study by Italian scientists, published in the July 1998 Proceedings of the National Academy of Sciences, found that anandamide inhibited the growth of breast cancer cells. Anandamide is the naturally occurring body chemical which is mimicked by cannabinoids. Other studies have shown that cannabinoids can also help prevent the death of brain cells during a stroke, head trauma and nerve gas exposure. [ 31 May 2006: Message edited by: Dana Larsen ]

Most of the harms caused by tobacco use are due not to tar, but to the use of radioactive fertilizers. Surprisingly, radiation seems to be the most dangerous and important factor behind tobacco lung damage. http://www.cannabisculture.com/news/tobacco [ 31 May 2006: Message edited by: Dana Larsen ]

Radiation is not contagious, it is a form of energy.

Fair enough. Interesting links, they make me regret my 10 years of smoking all the more. What fertilizers do large-scale grow-ops use? I know most of them aren't organic, and I know most of them are hydroponic. My question is - do they use the same kinds of fertilizers?

They might use similar fertilizers. But there would be differences.
Tobacco has high-phosphate fertilizers sprayed directly onto the leaves, even late into their growth cycle. Even the most fertilizer-crazy marijuana grower doesn't spray fertilizers directly onto the buds. That would ruin the product. Any decently grown bud goes through a no-fertilizer "flush" for at least the last few days if not the last week or two of their grow cycle. This is true in both Hydro and soil growing. Keep in mind also that commercial cigarettes don't contain actual tobacco leaf, they contain shredded paper that has been soaked in a tobacco juice solution.

If this study had been about a patented pharmaceutical instead of a herb, the headline would have been that the substance "protects against lung cancer." With the article I posted above, there is plenty of evidence that cannabis and cannabinoids have some pretty amazing anti-cancer properties. It seems likely that these substances are protecctive enough to more than counteract whatever negative things there might also be in raw marijuana smoke. It is a tragedy that so many people are suffering because we are not taking full advantage of the amazing curative properties found within the cannabis plant.

Cannabis Culture ran some articles about radioactivity in fertilizers during 2002 & 2004: Radioactive buds? http://cannabisculture.com/articles/2673.html The radioactivity debate http://cannabisculture.com/articles/3161.html In a legal, regulated environment, I think more people would use cannabis in safer and cleaner tincture and food products and less in smokable form, especially for medical use. Vaporizers are also a great technology, I enjoy my Volcano Vaporizer.

Dana, the Vaporizer works?? I've always been interested in it. Maybe off topic, maybe not, but I am a little sick of hearing the anti-weed crowd talk about pot lashed with this and that (meth, you name it). I have smoked pot for quite some time. I take a 6 month break every year, just so I can get things semi-clean again. Pot provides for me the following beneficial side effects: 1. Great for use against pain - period pain, lower back pain etc. proven results 2. Great for creativity 3. Instead of drinking alcohol when seeing a show and feeling like crap the next day, I prefer to smoke a joint. I wake up the next day and I feel fine. No hangover. 4. It's relatively cheap and lasts a long time (depending on how much you smoke). Honestly, the anti-weed crowd seems a bit strange to me. Most appear to attack weed, but don't level the same venom at alcohol (far worse) or cigarettes (even worse). To top that off, most of the anti-weed crows smokes cigarettes or drinks alcohol. I want to live in a society where my pot smoking is seen realistically i.e., as a much better alternative to alcohol and cigarettes.

This is the stupidest argument that I hear again and again. First off, weed is the cheapest of drugs. Lacing it with meth, crack, whatever, would only add to its cost. Why, then, would an unsuspecting buyer pay more for weed that they didn't know to be laced? Plus it would be terrible weed as most pot smokers aren't looking to get sketched out. The worst lacing I've encountered is when an unscrupulous dealer sold me weed laced with oregano. Chincy bastard...

It's a lie aimed to make marijuana more scary by associating it with other, more dangerous substances. If marijuana was being laced with meth it would taste terrible, the weed would obviously look laced, and it would not be a fun smoke. Health Canada doesn't have any records of marijuana they have seized which contained meth. This is just something the police say without ever providing any evidence.

And the occasional, even daily spliff probably does less lung damage than living in a metropolitan area and breathing all the SUV fumes.
Oddly enough, I'm partial to hanging out with people on ecstasy even though I would never touch the shit myself. I love blabbing with and listening to people, and people on E are so stimulated that they have to burn off the energy somehow, and there's nothing like blabbing your head off when the dance floor's dead. Furthermore, they always seem to want to smoke, whether they join my sesh (which tends to involve 2 joints, a core group of 3 to 5 people, and a revolving door of other people who just want a toke or two) or offer to smoke me up. As for legalisation killing the doobie or the pipe, that ain't going to happen: They're convenient, they're heavily engrained in stoner cultuer, and there's just a nice bit of romanticism in the social experience of rollin' and smokin' as a gang.

It is the Western culture's ritualist 'passing of the joint' whenever a person lits up that presents the greatest health risk. TB, herpes, cankers, flu and a host of other illnesses are easily passed this way. In Europe you smoke your own. Much more sensible and sanitary. Personally i prefer to light up my own and will pass it if anyone sparks an interest. But i never take it back, nor do i take anyone else's. Today i figure since i no longer have to endure the 90 minute commute to and from 'work' anymore, i am no more at risk of lung damage than i was in all that traffic for 25 years.

True, although generally speaking this is a fairly low risk, especially if you know the people you're smoking with. You have about as much chance of infection, from what I know, from just shaking the hand of someone with a contagious disease, or even from riding public transit. Our neo-Victorian ideals of cleanliness can get a little exaggerated at times. Having lived in Amsterdam, I found the Dutch style of smoking individual joints to be very strange and somewhat asocial. Nothing beats the communal aspect of sharing a joint.
