Study Shows Toxins In Marijuana Smoke

Levels Of Some Toxins Higher In Pot Cigarettes Than In Tobacco Cigarettes, Experts Say

(WebMD)  New research from Canada shows that some toxins may be more abundant in marijuana cigarettes than tobacco cigarettes.

The researchers burned 30 marijuana cigarettes and 30 tobacco cigarettes on a machine in their lab, measuring levels of chemicals in the smoke.

Ammonia levels were up to 20 times higher in marijuana smoke than in tobacco smoke.  Levels of hydrogen cyanide and nitrogen-related chemicals were three to five times higher in marijuana smoke than in tobacco smoke.

The nitrogen-based fertilizer used on the marijuana plants -- which all came from the same batch of Canadian pot plants -- may have affected the results.
The temperatures used to burn the cigarettes may also have been a factor.

Marijuana smoke and tobacco smoke shared many of the same chemicals. But the two types of smoke weren't identical.

For instance, marijuana doesn't contain nicotine. And tobacco doesn't contain cannabinoids, which include THC, marijuana's active ingredient

Tobacco has long been linked to cancer and other health problems. Marijuana smoke hasn't been tied to cancer in the past, note the
researchers, who included David Moir of the Safe Environments Programme in
Kitchener, Ontario.

Moir and colleagues report their findings in the advance online edition of
Chemical Research in Toxicology.

They promise to compare the toxicity of marijuana smoke and tobacco smoke in
animals in another study.

Legalize Marijuana!!! For a better, peaceful America!!!

Roll it up,
Light it up,
Smoke it up,
Inhale...Exhale!!!

"Tobacco has long been linked to cancer and other health problems. Marijuana smoke hasn''t been tied to cancer in the past...."

So they think they''ll find ties of this in the future? I don''t think so!!!

[rushman71]

"They promise to compare the toxicity of marijuana smoke and tobacco smoke in

They already know how toxic tobacco is, but the way things have been going on for centuries, will never prove that Cannabis is lethal or harmful in any way.

I''d be interested to know what kind of paper and glue were used in the "cigarettes," since that''s where some of tobacco-filled cigarettes'' toxins come from. It would have been a better test simply to burn tobacco and marijuana rather than "cigarettes," which introduces an unnecessary variable. But then the results would have made marijuana look better, and Big Pharma can''t have that, can they?

I recommend that we all try to find out who sponsors the Safe Environments Programme and this research. "Follow the money."

Another myth about pot smoking is that casual marijuana use does not stay in ones urine for weeks on end as we have all been lead to believe from the Republicons War on the American pot smoker. Weekend pot use only will disappear from ones system within 24 hours, I know this from experience.

However, these substances will remain in the body based upon body density, fluid intake/output and other factors. While some extremely slender persons may be able to eliminate it from their body over a weekend, some obese persons will retain it longer. It may be stored in the fat cells of the body.

You''''ll see me tonight
With an illegal smile.
It don''''t cost very much,
But it lasts a long while.

Please tell the man
I didn''''t kill anyone.
I''''m just trying
To have me some fun.

They need to do this study using a water pipe. That seems to be the preferred method, not joints.

[gunownerdan]

This looks like just another flawed study.
Cigarettes have filters, joints don''t.
People who smoke cigarettes often smoke 20 - 40 cigarettes a day.
People who smoke marijuana don''t often smoke more than one or two joints a day.
I bet this "study" is just more government-funded "reefer madness" style propaganda.

[rru2s]

As a chemist, this news article misses the boat completely.

Ask any toxicologist, and they will tell you the biggest danger in smoke is cancer causing polyaromatic hydrocarbons, which are the basic byproducts of combustion. Their concentration is up in the percentage level -- heck, that is essentially what makes up the bulk of "tar" and "soot" that is the main ingredient in all plant-source smoke.

So both marijuana and tobacco create lots of carcinogens. Lung cancer is the most likely mortality caused by chronic inhalation of smoke.

[gunownerdan]

Marijuana has been illegal for over 70 years and today it is America''s #1 cash crop.
This means BILLIONS of dollars are going right into the hands of drug gangs and drug dealers because of their monopoly on all black market profits.
To fight crime and violence, cops say LEGALIZE and REGULATE MARIJUANA!

So where do I sign up for the next study?

[mswolfestock]

Thirty cigarettes vs. thirty joints doesn''t sound very scientific to me. A heavy smoker might smoke 30 cigs every day, but holy cow, 30 joints in a day? C''mon, that is ridiculous. That''s probably much more than what the hard-core Rastafarians in Jamaica smoke. If the stuff in the joint is good enough, then 30 joints ought to last 30 days. If you tried to smoke 30 joints in one day you''d either get a huge headache if the pot was lousy, or you''d probably pass out after one or two joints if the stuff was really good. And who in the heck has that kind of money and time to smoke 30 joints a day. This sounds like something out of the Seventies, like something in a Cheech and Chong movie. Can I volunteer for their study anyway? Why did they waste the pot on a machine - that is a crying shame.

[afmca]

Was this study commissioned by the cigarette industry? Maybe they are just trying to tell every one to smoke their cancer sticks instead of marijuana. What I think the study proves is if marijuana is illegal then cigarettes should be illegal too. Close down the tobacco industry and raise the level of health throughout the world.

[latazman]

DUH!!!! If it burns it will put off some sore of toxin! I think the dopes are in the lab waisting good research money.

[far_point200]

Hmmm... When I smoked, I did smoke 30 cigs in a day, but 30 joints.... I don''t think so. And I didn''t know of any one else who did either.

I think the study may be just a little bit twisted! No pun intended!

[rushman71]

More SBS from CBS!!! This is so much a conspiracy against us Americans!!! Why the he11 would they make it illegal to smoke a joint, but it''s legal to go out and drink?!?!?! Because, they can''t control the production!!! It''s the money that the government cares more for!!! They would care less whether or not you would die from taking a drag!!!

[carlylaine]

Keep your nasty fingers off my pot! MORONs CONTROL FREAKS! Allow me to determine what I want for me. STOP! telling me how to live my life!!! BUTT OUT!!!

[briannorwood]

Toxins in marijuana smoke? Who woulda thunk!

"The CHEMICAL diacetyl has been linked to ... a rare life-threatening disease often called popcorn lung".

Diacetyl is a NATURAL substance which gives butter its NATURAL flavor. It is manufactured by the action of a micro-organism (the NATURAL process of fermentation) on a NATURAL substrate, whey.

Diacetyl is wholly NATURAL, there is absolutely nothing CHEMICAL (in the sense that you mean) about it at all.

FeelFree1, why don''t you spend some time studying basic biochemistry instead of wasting ours with your ignorant opinions?
