What has more carcinogens: marijuana or tobacco?

What has more carcinogens: marijuana or tobacco?

Tobacco: It has been intensely studied, but the lack of studies does not mean there is no risk to inhaling weed, the risk is just less well known and less well proven. The demonizing of marijuana as an 'entry drug' may be true in those susceptible, but it also has led to difficulties studying its effects, .

Carcinogen (Definition)

If marijuana has more carcinogens than cigarettes (as most doctors say) than why is it not definitively linked to cancer like tobacco is?

If marijuana has more carcinogens than cigarettes (as most doctors say) than why is it not definitively linked to cancer like tobacco is?

Says who?: We know less than we wish we did about cannabis, and we're simply not seeing cancer wards full of stoners despite the drug having been part of life in the US for decades. Much of the scare stuff we've been told during these decades is politics. Forgive me -- anybody who claims that "most doctors say" the stuff has "more carcinogens than tobacco" is simply lying to you for their own reasons.

Will smoking marijuana cause cancer/is it carcinogenic? If so, is it worse than smoking tobacco?

Will smoking marijuana cause cancer/is it carcinogenic? If so, is it worse than smoking tobacco?

Potentially: Unfiltered smoke contains chemicals that can promote the development of cancer, regardless of whether it is tobacco or marijuana. Putting a number on that risk is difficult because it depends what kinds of paper are used, and what additives are included when rolling these. This is just another reason to never use tobacco or marijuana.

Is marijuana safer than tobacco smoke?

Is marijuana safer than tobacco smoke?

Depends: Any form of smoking may produce benzene derivatives, which are cacerogens. However, there are studies which estimate that cannabis smokers have less incidence of lung cancer than both cigarette smokers and non-smokers. My advice would be not to smoke, period. If you use cannabis as a legal treatment, there are other formulations available besides smoking; sativex, marinol, etc.

How do marijuana, alcohol, and tobacco effect the reproductive health?

How do marijuana, alcohol, and tobacco effect the reproductive health?

No surprise: Are you surprised if I say they all affect reproductive health in a bad way. Mild or even moderate alcohol use may have a negligible effect, but tobacco and marijuana are definitely harmful: the more you use, the worse the problem.

Is it true that smoking marijuana affects erections the same way smoking tobacco does?

Is it true that smoking marijuana affects erections the same way smoking tobacco does?

Yes: Marijuana and low testosterone: the two go hand in hand. Yes, marijuana is a "herb". Yes, marijuana is a "natural plant". However, none of that is going to change the fact that marijuana is a one way ticket to low testosterone, erectile dysfunction and fertility problems. The political debate regarding marijuana may be interesting, but the research shows it to be debilitating and harmful.

Why do some doctors say marijuana can cause cancer while other doctors say no it cant? Cant we get a definitive yes or no like we did with tobacco?

Why do some doctors say marijuana can cause cancer while other doctors say no it cant? Cant we get a definitive yes or no like we did with tobacco?

No: There is no evidence that marijuana causes cancer but there is also insufficient research on marijuana - primarily due to it still being classified by the U.S. Govt as Schedule 1 which limits research on it. Therefore, those who say it does cause cancer are not basing it on any research whatsoever but there haven't been long-term trials or registeries to entirely refute that either.

I have severe asthma, and I was wondering if being near tobacco/marijuana smoke could’ve taken me from a cold to bronchitis. Kids on my floor smoke.?

I have severe asthma, and I was wondering if being near tobacco/marijuana smoke could’ve taken me from a cold to bronchitis. Kids on my floor smoke.?

Asthma Exacerbation: You need an immediate in person exam to rule out asthma exacerbation. Studies show that patients managed with only a rescue inhaler can develop exacerbations related to allergens or seasonal allergies. If wheezing is detected on exam, steroids and nebulizer treatment can help you achieve comfort. Antibiotic coverage if indicated based on exam to cover upper respiratory infection, and full eval

Is marijuana and ecstasy less dangerous than alcohol and tobacco?

Is marijuana and ecstasy less dangerous than alcohol and tobacco?

Different dangers: Too little is known about ecstasy for anybody to say. Right or wrong, marijuana is illegal and poses dangers to you, from job loss to making it impossible for you to get an organ transplant to cure your alcoholic liver disease. That alcohol ruins the lives of abusers & their families is obvious, and tobacco is the great avoidable life-shortener of the world. How about "none of the above" for you?

Is smoking marijuana as bad for me as smoking tobacco?

Is smoking marijuana as bad for me as smoking tobacco?

Research is mixed: According to the national institute of drug abuse, marijuana smoke contains 50-70% more carcinogens than tobacco smoke. Also marijuana smokers inhale more deeply and hold smoke in their lungs longer. Http://www. Drugabuse. Gov/publications/drugfacts/marijuana these can lead to more lung irritation and cancer. Other studies say mj is not linked to tobacco-related cancers (lung, colon, rectal, etc).

Does marijuana or tobacco do less damage to your lungs?

Does marijuana or tobacco do less damage to your lungs?

Depends: A recent study by the british lung foundation found that just three cannabis joints a day cause the same damage as 20 cigarettes, and when cannabis and tobacco are smoked together, the effects are dramatically worse. They report that the tar from cannabis cigarettes contains 50% more cancer causing carcinogens than tobacco.

Is smoking marijuana less dangerous for you than smoking tobacco?

Is smoking marijuana less dangerous for you than smoking tobacco?

Both dangerous: Both are dangerous. Marijuana smoke has more carcinogens in it than regular cigarettes do, and people usually inhale and hold the smoke longer with it too. So exposure is very significant -- plus the unspecified additives and possible pesticides that no one really checks for. Alternatively, nicotine is highly addictive, and people usually smoke more regular cigarettes, more often. Neither is good.

Would occasional marijuana use cause health problems just like tobacco would?

Would occasional marijuana use cause health problems just like tobacco would?

Much safer but...: Tobacco use dramatically increases risk of many cancers, heart disease, strokes & chronic lung disease. Marijuana hasn't been proven to increase risk of these (except regular use can increase lung disease) & in general is far safer than tobacco. However, regular use before age 18 is associated with long-term lowered IQ so I advise extreme caution re: use in adolescence. See http://bit. Ly/STxBwe

Is smoking organic marijuana as dangerous as smoking tobacco on the pancreas? Vapor a better choice?

Is smoking organic marijuana as dangerous as smoking tobacco on the pancreas? Vapor a better choice?

Why pancreas concern: I'd worry much more about my lungs, heart and brain if I was smoking anything because these are what are likely to go first and kill or impair you than your pancreas not working well will. And no, vapor is not a better choice.

Is a small dose of Methamphetamine safe (its clean) I've quit opiates tobacco, marijuana, benzo 11 days. Meth I'm taking 1 small dose in the morning.

NO: Not safe! You think it's clean, but unless it was manufactured in a commercial pharmacy with government oversight (or you made it yourself), you don't really know what you're getting.

I was a heavy smoker for 3 years or so. Mixing tobacco with marijuana. Have recently quit but spit up a lot of tar. Is this a good sign or bad one?

I was a heavy smoker for 3 years or so. Mixing tobacco with marijuana. Have recently quit but spit up a lot of tar. Is this a good sign or bad one?

Tar: cleaning out: It is a good sign. It is often difficult for actively smoking humans to clean up or clear out their lungs. It surprises some that in the early months after quitting smoking they cough more and often have more productive junk when they cough. But, as your lungs clear out this tar and other waste products you will get to a healthier ability to breath and the lungs can begin to heal.

How possible is it to have oral cancer at age 24? I don't do dip or tobacco barely drink I do smoke marijuana although I stopped a month ago.

How possible is it to have oral cancer at age 24? I don't do dip or tobacco barely drink I do smoke marijuana although I stopped a month ago.

Oral cancer: Yes, it's possible. If you have a new sore or rough area that does not heal within 7-10 days it needs to be examined by your dentist or an oral surgeon. In any case, if you are concerned about any area in your mouth, have it examined by your dentist.
