Marijuana Smoke More Toxic Than Cigarette Smoke?

[dav3]

ScienceDaily (Dec. 18, 2007) ? Here's another reason to "keep off the grass." Researchers in Canada report that marijuana smoke contains significantly higher levels of several toxic compounds -- including ammonia and hydrogen cyanide -- than tobacco smoke and may therefore pose similar health risks.

David Moir and colleagues note that researchers have conducted extensive studies on the chemical composition of tobacco smoke, which contains a host of toxic substances, including about 50 that can cause cancer. However, there has been relatively little research on the chemical composition of marijuana smoke.

In this new study, researchers compared marijuana smoke to tobacco smoke, using smoking machines to simulate the smoking habits of users. The scientists found that ammonia levels were 20 times higher in the marijuana smoke than in the tobacco smoke, while hydrogen cyanide, nitric oxide and certain aromatic amines occurred at levels 3-5 times higher in the marijuana smoke, they say. The finding is "important information for public health and communication of the risk related to exposure to such materials," say the researchers.

The study, "A Comparison of Mainstream and Sidestream Marijuana and Tobacco Cigarette Smoke Produced under Two Machine Smoking Conditions," is scheduled for the Dec. 17 issue of ACS' Chemical Research in Toxicology.

interesting read

[cool1]

and car exhaust is just as bad for you as second hand smoke whether it is from cigs or pot.
so maybe everyone should quit smoking cigs and weed and stop driving thier cars.

Thats nothing buy journalistic and scientific propaganda. How many people have died from cigarettes and how many from marijuana? One is manufactured in a factory including many chemicals, and the other grows naturally from the ground and has existed naturally for as long as man.

I'm not saying marijuana is good for you, but please.....

Notice how they don't say who FUNDED the study?

Vaporize.

Don't let the propaganda monkeys get you. 100X better than smoking.

In every sceintific experiment there must be control.Without control the results canot be used as fact.

marlboro ciggarrettes are pruduced under strict control and every sample would be just about exactly the same.

Marijuna that is smoked is not under control and the varieties are endless.


Was the marijuna that was used for this test grown indoors hydroponically,harvested and then "smoked" within a certain time after harvesting?

laymans terms...

They probably used rag "street" marijuna that was grown outdoors in mass with chemical additives added during and after harvest for varuious resons like pest control or odor control..if they used some hydro results would have been alot different.

I have to I have my doubts about the accuracy of those numbers as well. I am not a pot head, but I know that there is a lot of anti-weed propaganda. Plus the manufacturing process of cigarettes is just insane.

May be they will claim that the chemicals they use to extract the nicotine from tobacco leaves actually purifies it and makes it healthier for you... LOL...

Fuck it,we are all going to die someday..I'll puff away

Makes me high.

Without trying to be a troll:
1 - Tobacco grows in the ground, and has done naturally for centuries.
2 - Weed grows in the ground and has done naturally.
3 - Poisonous plants have grown in the ground naturally for centuries.

What's your point? Just because it grows in the dirt doesn't mean it's good, or bad for you.

Not to mention, you can't even begin to draw comparisions between weed - bush versus hydro, etc. They're completely different.

Sounds like you're trying to justify your own habits.

The thing is a person usually smokes alot more cigarettes than marijuana.

science daily pushes intelligent design
enough said about that site

[Iron Fist]

NO way duuuuuuuuuuuuuuuuuddddeeeeee....

Exactly - 5 or 10 good hits and your rolling for hours and hours, and you won't necessarily smoke up again for a while. Cigarette smoking is all day every day, in some cases multiple PACKS per day, certainly every few hours at the least.

Having said all that: vaporize!

[ThreeXes]

Good thing that you don't smoke 2 packs of jays/day!

If anyone was going to die of cancer from smoking weed..it would have been my dad.. he is healthy as a horse and outsmokes anyone I know ..he is 67 this year.

He used to be a heavy pall mall smoker when I was little, but he quit about 30 years ago.

Ha ha, your debate is quite elementry.
There are not very high paid scientists in labs right now working on chemicals to make you much more addicted to marijuana like they are with ciggerettes. Marijuana also does not have the chemicals that cause cancer...

A cigarette is a product consumed via smoking and manufactured out of cured and finely cut tobacco leaves and reconstituted tobacco, combined with other additives,[1] then rolled or stuffed into a paper-wrapped cylinder (generally less than 120 mm in length and 10 mm in diameter). The cigarette is ignited at one end and allowed to smoulder for the purpose of inhalation of its smoke from the other (usually filtered) end, which is inserted in the mouth. They are sometimes smoked with a cigarette holder. The term cigarette, as commonly used, refers to a tobacco cigarette but can apply to similar devices containing other herbs, such as cannabis. They are colloquially known as "cigs", "ciggies", "cancer sticks", "coffin nails", "death sticks", "smokes","lung-rockets", "grets", "bogies", "fags", and "stogies".

Cigarettes are proven to be highly addictive, as well as a cause of multiple types of cancer, heart disease, respiratory disease, circulatory disease, birth defects and emphysema.[2][3]

A cigarette is distinguished from a cigar by its smaller size, use of processed leaf, and white paper wrapping. Cigars are typically composed entirely of whole-leaf tobacco.

Cigarettes contain nicotine, an addictive stimulant which is toxic. They deliver smoke to the lungs immediately and produce a rapid psychoactive effect.[4]
