yeah they said it. marijuana isnt linked to lung cancer

"LOS ANGELES - Marijuana smoking does not increase a person's risk of developing lung cancer, according to the findings of a new study at the University of California Los Angeles that surprised even the researchers."

JEA
 
what that says is that smoking WEED is no worse than cigs. but it is the smoking that messes up your lungs not the THC. it is the tar entering your lungs that does the dammage. the tar present in all smoke.
 
I'm sorry, but 611 cancer patients, 601 with other cancers and 1040 without cancer doesn't seem reprensentative. Also, they did not take in account other factors that can contribute to cancer neither.

"Previous studies showed marijuana tar contained about 50 percent more of the chemicals linked to lung cancer, compared with tobacco tar, Tashkin said. In addition, smoking a marijuana joint deposits four times more tar in the lungs than smoking an equivalent amount of tobacco."

Im not convinced at all.
 
i love how all the scientists are trying to find loopholes for the findings. the fact is that weed isn't bad for you
 
Yes, carcinogens(sp) going into your lungs, abosrbing into your airs sacks of your lungs isnt bad for you. Hmm sounds like something else involving smoke, OH CIGS! Same damn thing. Weed is NOT good for you, and does the same thing cigs do to you. But like that actical said, there is much more tobacco in a cig than say a joint would have weed(depending on how much u put in) and people smoked 1-2 packs a day if not more, which would be like smoking 40 joints a day, which a stoner might go through in 1.5-2 months.

So weed is just as bad as tobacco, its just people use tobacco much more often, causing more tar build up, causing more cancer.
 
"In addition, smoking a marijuana joint deposits four times more tar in the lungs than smoking an equivalent amount of tobacco."

awww mannnnn
 
ive heard that THC actually opens up your pores or whatever in your lung, allowing for the tar to escape, where as sigs contract the pores
 
sounds like in terms of getting cancer, cigaretts are worse, but weed delivers 4 times as much tar... and that cant be to good.
 
im pretty sure that if they were doing research on it then they did take into account all that was nessicary. as for the tar build-up; the only reason its more is because weed smokers hold the smoke in for "anbout four times longer than tobacco," and it also says that the THC kills cells, but among those are cancerous cells, thus decreasing the chance of getting cancer
 
damn thats good to know. but doing it like once a month is nothing because your body can recover from in it fully during that time.

also they said something about more tar being enhaled from joints because its packed looser...smoking it from a bong wouldnt allow this because it goes through the water first and doesnt burn your lungs....wow weed is gods mightiest creation
 
k i hate when people say weed isnt bad for you because it is. only if you take it in moderation will it not be bad for you but those of you daily potheads are really getting impacted by it
 
omfg weed is bad for you!!!!!!!!!!

yea well take into consideration the way and amount people smoke. Bongs and bubblers filter the smoke, taking the tar most of the bad shit out. People dont smoke nearly as much pot as tobacco, unless your willie nelson. and read the article fully, theres no connection between lung cancer and pot! that means if you dont smoke cigarettes you have a very slim chance of getting lung cancer. weed is awesome. respect it
 
The article clearly state no link between pot and lung cancer. The four times the tar bullshit if from a "previous study" i.e. the previous studies that were proved wrong.

kthxbi
 
Pot Smoking Not Linked to Lung Cancer

Study Shows No Increased Risk for Even the Heaviest Marijuana Smokers

May 23, 2006 -- People who smoke marijuana do not appear to be at increased risk for developing lung cancerlung cancer, new research suggests.

While a clear increase in cancercancer risk was seen among cigarette smokers in the study, no such association was seen for regular cannabis users.

Even very heavy, long-term marijuana users who had smoked more than 22,000 joints over a lifetime seemed to have no greater risk than infrequent marijuana users or nonusers.

The findings surprised the study’s researchers, who expected to see an increase in cancer among people who smoked marijuana regularly in their youth.

“We know that there are as many or more carcinogens and co-carcinogens in marijuana smoke as in cigarettes,” researcher Donald Tashkin, MD, of UCLA’s David Geffen School of Medicine tells WebMD. “But we did not find any evidence for an increase in cancer risk for even heavy marijuana smoking.” Carcinogens are substances that cause cancer.

Tashkin presented the findings today at The American Thoracic Society’s 102nd International Conference, held in San Diego.

Boomers Reaching Cancer Age

The study population was limited to people who were younger than 60 because people older than that would probably not have used marijuana in their teens and early adult years.

“People who may have smoked marijuana in their youth are just now getting to the age when cancers are being seen,” Tashkin says.

A total of 611 lung cancer patients living in Los Angeles County, and 601 patients with other cancers of the head and neck were compared with 1,040 people without cancer matched for age, sex, and the neighborhood they lived in.

All the participants were asked about lifetime use of marijuana, tobacco, and alcohol, as well as other drugs, their diets, occupation, family history of lung cancer, and socioeconomic status.

The heaviest marijuana users in the study had smoked more than 22,000 joints, while moderately heavy smokers had smoked between 11,000 and 22,000 joints.

While two-pack-a-day or more cigarette smokers were found to have a 20-fold increase in lung cancer risk, no elevation in risk was seen for even the very heaviest marijuana smokers.

The more tobacco a person smoked, the greater their risk of developing lung cancer and other cancers of the head and neck. But people who smoked more marijuana were not at increased risk compared with people who smoked less and people who didn’t smoke at all.

The THC Connection

Studies suggest that marijuana smoke contains 50% higher concentrations of chemicals linked to lung cancerlung cancer than cigarette smoke. Marijuana smokers also tend to inhale deeper than cigarette smokers and hold the inhaled smoke in their lungs longer.

So why isn’t smoking marijuana as dangerous as smoking cigarettes in terms of cancercancer risk?

The answer isn’t clear, but the experts say it might have something to do with tetrahydrocannabinol, or THC, which is a chemical found in marijuana smoke.

Cellular studies and even some studies in animal models suggest that THC has antitumor properties, either by encouraging the death of genetically damaged cells that can become cancerous or by restricting the development of the blood supply that feeds tumors, Tashkin tells WebMD.

In a review of the research published last fall, University of Colorado molecular biologist Robert Melamede, PhD, concluded that the THC in cannabis seems to lessen the tumor-promoting properties of marijuana smoke.

The nicotine in tobacco has been shown to inhibit the destruction of cancer-causing cells, Melamede tells WebMD. THC does not appear to do this and may even do the opposite.

While there was a suggestion in the newly reported study that smoking marijuana is weakly protective against lung cancer, Tashkin says the very weak association was probably due to chance.

Cancer risk among cigarette smokers was not influenced by whether or not they also smoked marijuana.

“We saw no interaction between marijuana and tobacco, and we certainly would not recommend that people smoke marijuana to protect themselves against cancer,” he says.
 
it does have its medical benefits such as relieving pain, but it is still not good for you. it is still not exceptionally good for your lungs, and it certainly isn't good for your brain.
