I cant really be bothered to get anymore, but google will be all you need to educate yourselves with the hundreds of other positive things weed does, every damn day.

Bob Marley said "Weed is so good for everyting" and it IS.

LOL I think we should get a new sub folder for all this propaganda bullshit.

we need to create a website that is strictly anti-propoganda

Here's the real study results. They looked at "macroscopic emphysema". The emphysema was detected in 1 out of 75 of the cannabis only smokers, 15 of 92 people who smoke cannabis plus tobacco, 17 of 91 tobacco only smokers, and no emphysema for non smokers. So cannabis alone only resulted in one case of emphysema, but tobacco resulted in many cases of emphysema. I don't know how they decided that one cannabis joint impairs the lungs more than tobacco because I can't read the whole study, but it sounds like something that they measured acutely, and not chronically, as cannabis didn't really cause emphysema. Never believe the news, always read the study or the study abstract. This is just like the studies that link psychosis with cannabis use, they say that someone who went a little crazy smoked literally one joint when they were a teenager, so that means that the cannabis had something to do with it. While they were smoking lots of tobacco, which people with mental illness smoke more than other people. But the studies say oh no, the tobacco is smokked because it helps to calm them. Well as it just so happens cannabidiol, the second main cannabinoid is cannabis, is a powerful antipsychotic, so they were more likely mentally ill before they smoked cannabis, and cannabis helped them.

THE EFFECTS OF CANNABIS ON PULMONARY STRUCTURE, FUNCTION AND SYMPTOMS.

BACKGROUND: Cannabis is the most widely used illegal drug worldwide. Long term use of cannabis is known to cause chronic bronchitis and airflow obstruction, however the frequency of macroscopic emphysema, the dose-response relationship and the dose equivalence of cannabis with tobacco has not been determined. METHODS: A convenience sample of adults from the Greater Wellington Region was recruited into four smoking groups; cannabis only, tobacco only, combined cannabis and tobacco and non-smokers of either substance. Their respiratory status was assessed using high resolution CT scanning, pulmonary function tests and a respiratory and smoking questionnaire. Associations between respiratory status and cannabis use were examined by analysis of covariance and logistic regression. RESULTS: A total of 339 subjects were recruited into the four groups. A dose-response relationship was found between cannabis smoking and reduced FEV1/FVC and sGaw, and increased TLC. For measures of airflow obstruction, one cannabis joint had a similar effect to between 2.5 and 6 tobacco cigarettes. Cannabis smoking was associated with decreased lung density on HRCT scans. Macroscopic emphysema was detected in 1/75 (1.3%), 15/92 (16.3%), 17/91 (18.9%) and 0/81 subjects in the cannabis only, combined cannabis and tobacco, tobacco alone and non-smoking groups respectively. CONCLUSIONS: Smoking cannabis was associated with a dose-related impairment of large airways function resulting in airflow obstruction and hyperinflation. In contrast, cannabis smoking was seldom associated with macroscopic emphysema. The 1:2.5 to 6 dose equivalence between cannabis joints and tobacco cigarettes for adverse effects on lung function is of major public health significance.

[huh]

Cannibis kills cancerous cells? Really i just thought it helped with the nausia from Chemo, thats why cancer patient use it.Well at least I thought

its used for chemo because there is more than one reson it helps.
the help with nausia, appetite stimulation, pain relief, etc.

Im not sure if it causes cancer but it surely does damage your lungs overtime.

I dont think it has actually been proven that it kills cancerous cells. I mean chemists have been trying for years and years to find a compound that does. I think if THC was this magical the scientists would be able to use it to virtually eliminate all cancerous cells in a person.

THC cancels out the effect that tar has on cells, I dont beleive this. It isnt possible for it to be that straight forward.

I think weed is as good as the next person I just think that it isnt possible that cannabis smoke cannot cause cancer.

Sort of....

Cannabis smoke DOESN'T let you absorb PAH's (Polycyclic aromatic hydrocarbons) which are one of the key carcinogens in Tobacco smoke.

These PAH's fuck you up! Guess what - Nicotine enables them to bind and enter your system.

THC doesn't - it blocks it.

The difference rests in the often opposing actions of the nicotine in tobacco and the active ingredient, THC, in marijuana, says Dr. Robert Melamede of the University of Colorado in Colorado Springs. Whereas nicotine has several effects that promote lung and other types of cancer, THC acts in ways that counter the cancer-causing chemicals in marijuana smoke. Lab research indicates that nicotine activates a body enzyme that converts certain chemicals in both tobacco and marijuana smoke into cancer-promoting form. In contrast, studies in mice suggest that THC blocks this enzyme activity.

Smoke weed alone - no tobacco and cut the PAH's out, Tar my arse this is a smokescreen people!!!!

So LiP is also right too - the Devil is in the details my friends

Dean, darlin', click on the "medical studies" link in my sig. Start reading and get educated! I "double-dog-dare you" to read all the titles! - Granny:hippy:

[zsouj]

one of the guys who has studied a lot about marihuana smoke effects is Dr. Donald Tashkin (UCLA), he found out that cannabis smoke contains 4 times more tar than cig smoke

However, try tu calculate how much smoke does a cig smoker put into his lungs in a week, and compare that to the amount of smoke consumed by the only-cannabis smoker (like me), it's an absurd comparison.

Tashkin also found out NO association between cancer development and cannabis use, in fact he believes it might be possible that THC actually protects the cells from developing cancer.

There was like a History Channel Modern Marvels show about tobacco, and most cigarettes are only like 50 percent actual tobacco. The rest is this liquid tobacco chemical concentrate that they soak into paper shreds or tobacco shreds. Not something that people would want to smoke, and not very natural either.
