Study finds smoking marijuana and cocaine can cause cancer

WASHINGTON (CNN)-- In the first study of its kind, researchers found that smokers of marijuana and crack cocaine show the same kinds of precancerous conditions caused by smoking tobacco.

The findings were released Tuesday in the Journal of the National Cancer Institute.

In the study, researchers examined samples of respiratory tract tissue from participants who ranged in age from 21 to 50. To be eligible, the participants had to be in one or more of the following categories: Marijuana smokers who smoked an average of 10 or more marijuana cigarettes a week for the last five years or longer; crack cocaine smokers who smoked one gram or more of crack cocaine a week for nine months or longer within the past year; or tobacco smokers who smoked 20 cigarettes or more a day for the last five years.

The researchers looked at genetic markers known to be associated with increased risk of lung cancer. Changes or overproduction of some markers were found in a majority of the study participants.

The findings suggested that tobacco was not the only smoked substance that set the changes preceding lung cancer development in motion.

The study also showed that habitual smoking of tobacco, marijuana or crack cocaine in combination could potentially lead to more cancerous alterations in the molecular makeup of cellular structure than single-smoking alone.

Dr. Sanford Barsky, co-author of the study and a member of the University of California, Los Angeles' Jonnson Comprehensive Cancer Center, said he was not surprised by the findings. He said any substance that is inhaled, regardless of chemical makeup, releases carcinogens into the lungs and throat.

In an editorial accompanying the study, Dr Li Mao and Dr. Yun Oh at the University of Texas's M.D. Anderson Cancer Center conclude that the nationwide teen anti-tobacco effort might have an "unintended consequence" -- teens will substitute tobacco with marijuana.

They write while these anti-tobacco campaigns are expected to reduce the numbers of teenagers and children who smoke tobacco cigarettes, the rate of marijuana use is increasing.

They note the percentage of students smoking marijuana on a daily basis has risen from 1.9 percent in 1992 to 4.6 percent in 1995.

Previous scientific studies are still important because it is used as a basis for new cases of marijuana addiction today. The information presented here are factual since time and time again, marijuana can cause damages to the brain as well as to the internal organs. The best thing to do for young people is to stay away from this drug, in order to avoid its harmful effects.

Just what we need more slander on marijuana, lets totally not mention how marijuana has many beneficial medical qualities that have been proven to help patients with cancer, glaucoma, parkinson's disease, arthritis, and the terminally ill. How can our government legalize such harmful substances like alcohol and tobacco while condemning the relative harmless use of marijuana. Fact of the matter is, alcohol is involved in fifty percent of all driving fatalities. Alcohol is also known to induce incidents of traumatic injuries, suicide, and date rape. 76,000 people die from alcohol use each year in the U.S. alone. Over 5 million people die from tobacco use yearly. How many people die from marijuana use? ZERO. Still think marijuana is the problem?

maybe what you are telling is true, but the reason for the ban on marijuana is because its very difficult to come out of its addiction and its very easy to get addicted. it may be very beneficial in treating some diseases but only in the specified amount. in the open market it is as good as a bottle of poison.

I'm not oblivious to the fact that marijuana is self-destructive in some ways, but referring to it as a bottle of poison is harsh and inaccurate. If anything marijuana is a substance that masks away the bigger problems by providing immediate relief and happiness. It may also damage you financially, but marijuana is not easy to get addicted to. In fact, most people will not feel any addiction to marijuana from initial to moderate use. Addiction is formed through habitual use, which pretty much means smoking everyday for an extended period of time to the point where the brain starts to crave the high. And, even then the addiction felt by marijuana is nowhere near as strong as the addiction felt by cigarettes or any other illicit drug.

Seriously? I can only guess which hempfest this statistic comes from but if you like you can take a look at the CDC website and the US Census reports for cause of death. Hell there's a link to a study about people who causually got cancer from smoking pot right above you. Pot kills people. Most marijuana related deaths are from violence surrounding it's illeagal sale so legalizing it would affect the figure but it's no less debilitating than alcohol, when it's legal there will be more driving fatalities.

As far as marijuana being a carcinogen, really? They got that published in '98? They were talking about cancer risks from marijuana when I was in grade school. People who work in BBQ shacks get cancer from smoke, smoke is bad for your lungs. it causes cancer. Unlike tobacco marijuana can be enjoyed when it's carcinogens are filterred or leeched. I guess if you can take good health advice from this, don't put smoke where you breathe.

An exhaustive search of the literature finds no credible reports of deaths induced by marijuana. The US Drug Abuse Warning Network (DAWN) records instances of drug mentions in medical examiners' reports, and though marijuana is mentioned, it is usually in combination with alcohol or other drugs. The CDC has no reports of “marijuana-induced deaths". Marijuana Does Not Raise Lung Cancer Risk Article(http://www.foxnews.com/story/0,293 3,196678,00.html): While a clear increase in cancer 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.”
Okay, so as you can see I can find many articles like this that revoke the belief that marijuana causes cancer as I'm sure that you can find many articles that say the opposite. I do not revoke all evidence that says that marijuana can cause cancer, but the fact of the matter is most of the evidence out there that say marijuana causes cancer is mere speculation. And due to the lack of this evidence many statistics are allowed to say that marijuana does not cause any fatalities. But, i'm not so ignorant as to believe in everything I read and truth be told I would not be surprised if many people have gotten cancer from marijuana. But, what doesnt cause cancer nowadays? I'm sure if you made a list of all your actions on a given day you'd find out that many of the things you consume or inhale are linked to cancer. And, your only kidding yourself if you believe that the prohibition of marijuana works. As you said, most marijuana related deaths are from violence surrounding its illegal sale. Whether illegal or legal people are gonna find ways to smoke pot; it is the most used illicit drug in the United States. Keeping marijuana illegal only brings financial support to criminals such as the cartel. According to Jeffery Alan Miron, the author of, “Budgetary Implications of Marijuana Prohibition in the United States”, the Government would earn 14 billion dollars annually if marijuana were taxed in the same rate as alcohol or tobacco. That money would create a new job market and reduce the percentage of unemployment. And your belief on how marijuana is no less debilitating than alcohol really astonishes me as I cannot believe that anybody actually thinks that. You should go check out this article and really do the research behind it cause I'm pretty sure you would change your mind: http://www.saferchoice.org/content/view/24 /53

I'm sorry, this isn't an argument. You have admitted marijuana when smoked is a carcinogen. A carcinogen is by definition a cancer-causing agent. Whether marijuana jumps out of our dime bag and stabs you to death or whether you die of complications or incidents related to marijuana you are still 100% dead. You're not permitted to talk about zero marijuana deaths in the same argument where you talk about lower instance of marijuana deaths. That is a rule that I have no choice but to enforce.

If Marijuana never killed a soul it would still be a dangerous narcotic, no less dangerous than alcohol or prescription pills when abused but not the magical weed that makes all things better. There will always be people who cannot control their use of a drug and it won't matter much what drug they abuse, it will cause them and others harm.

Who are you to say who can speak or not, your mother obviously never taught you any manners. If proving your point is so important to you that you feel the need to twist and misconstrue statements then go right ahead and have what little pride you get from all of this. Arguing with narrow minded people such as yourself is pointless and an incredible waste of time. You should realize at some point of your life that not every conversation is an argument and that people are entitled to believe what they want to even if it contradicts what you think because you are not the absolute truth. Step off your high horse and stop thinking your better than everybody else. I haven't even met you in person and I can already tell from the way you speak that you have a superiority complex and are very argumentative. Both repulsive characteristics that you may want to change at some point of your life.

I'm confused as to why you don't imagine I have a right to correct you when you deliberately lie to others. I'll go ahead and say it again, No lying, especially if you're contradicting yourself. If you believe my insistence that you not deliberately deceive and confuse others somehow makes me better than you, you may be on to something there.

As long as you're wasting your time by criticizing me for correcting you I may as well give you a few more things for you to get incited about. Marijuana is a legitimate medical drug, however for just about every medical application it has it is a less effective drug than manufactured pharmaceuticals and has more severe side effects. Also having medical benefits doesn't make a drug good. LSD was prescribed for psychosis, Cocaine derivatives were used to treat ADHD, Alcohol was used to treat anxiety and primitive formulas of MDMA were used to treat depression. Very few illegal drugs weren't medical drugs at some point somewhere in the world.

Here you go again trying to make a stupid argument out of nothing cause that's what you do best. I've said it before and I'll say it again arguing with narrow-minded people such as yourself is pointless and an incredible waste of time, go find someone else to argue with cause I'm not going to give you the satisfaction.

Listen UP
I'm a police officer and I can tell you that weed does more harm from wasting tax payers money trying to control it, then actually smoking it. Lets get the facts out in the open. 1) Weed can't kill you from an overdose. You can smoke a truck load of marijuana and not die . This is crazy to think of I know, but it is fact. 2) Alcohol can kill a 200 pound person with one bottle of strong liquor, it's called alcohol poisoning. Nicotine can kill you very quickly as well, if taken in excess it will stop the heart and respiratory system. I heard of people trying to kill others in their sleep by applying nicotine patches to them in their sleep. Believe me this would work. Weed can not kill you of an overdose, you can smoke all day everyday and no death. We could be saving billions of dollars if it was legal. Just incase your wondering I don't smoke, but I keep putting people in jail for its distribution. I feel that Mexican cartels are making all the money from the weed smoked in the U.S. I think if we legalized it America would not have to buy it from such dangerous people.
