has any one seen this b4?

Many people think smoking marijuana is just as harmful as
smoking tobacco, but this is not true. Those who hold that
marijuana is equivalent to tobacco are misinformed. Due to the
efforts of various federal agencies to discourage use of
marijuana in the 1970's the government, in a fit of "reefer
madness," conducted several biased studies designed to return
results that would equate marijuana smoking with tobacco smoking,
or worse.
For example the Berkeley carcinogenic tar studies of the
late 1970's concluded that "marijuana is one-and-a-half times as
carcinogenic as tobacco." This finding was based solely on the
tar content of cannabis leaves compared to that of tobacco, and
did not take radioactivity into consideration. (Cannabis tars do
not contain radioactive materials.) In addition, it was not
considered that:
1) Most marijuana smokers smoke the bud, not the leaf, of
the plant. The bud contains only 33% as much tar as tobacco.
2) Marijuana smokers do not smoke anywhere near as much as
tobacco smokers, due to the psychoactive effects of cannabis.
3) Not one case of lung cancer has ever been successfully
linked to marijuana use.
4) Cannabis, unlike tobacco, does not cause any narrowing of
the small air passageways in the lungs.
In fact, marijuana has been shown to be an expectorant and
actually dilates the air channels it comes in contact with. This
is why many asthma sufferers look to marijuana to provide relief.
Doctors have postulated that marijuana may, in this respect, be
more effective than all of the prescription drugs on the market.
Studies even show that due to marijuana's ability to clear
the lungs of smog, pollutants, and cigarette smoke, it may
actually reduce your risk of emphysema, bronchitis, and lung
cancer. Smokers of cannabis have been shown to outlive non-
smokers in some areas by up to two years. Medium to heavy
tobacco smokers will live seven to ten years longer if they also
smoke marijuana.
Cannabis is also radically different from tobacco in that it
does not contain nicotine and is not addictive. The psychoactive
ingredient in marijuana, THC, has been accused of causing brain
and genetic damage, but these studies have all been disproven.
In fact, the DEA's own Administrative Law Judge Francis Young has
declared that "marijuana in its natural form is far safer than
many foods we commonly consume."


found just above center of page. other information about tobacco is very interesting as well.

Yes dude, its old news. Sorry.

And for future referance pretty much everyone on here's read every single thing in Erowid' cannabis vault.

 

It may be old news, but it's worth a refresh to my memory.

Mellow, can you honestly say that you can repeat every positive thing you've read about weed on cue, when in a dispute?

Better to know your stuff than to seem like a rambling dumbass with no presentable data, right?

We need a sticky with all collected studies and articles, not only erowid's.

 

Good info, im saving it

 

^^^^ True true, I've also heard all of the stuff before but I forgot some of the few smaller things that can make arguments that much stronger.

 

these articles ignore aromatic compounds in the plant smoke unfortunately, which is where ive found the opposite side of the arguement to be unopposable so far. benzene-based chemicals in the smoke are carcinogens. they have been found in the smoke. this is the fundamental and final response ive found from those who believe weed will cause cancer. no one has ever been shown to die from it of course, but then again, cancer statistics only started being compiled relatively recently in the thousands of years weed has been used for. if people start dying from cancer from weed is gonna be this time period now probably. but i think its not gonna happen, the dilating effects of weed and lack of radioactive chemicals clearly makes a huge difference/. tar doesnt cause cancer anyway

 

You sure on that?

 

bill usually knows what he's on about man. look - he has a phd in advanced bongology. respect.

 

This is from http://www.nhsdirect.nhs.uk/articles/article.aspx?printPage=1&articleId=437

Am I to believe this?

 

tar = bummer

 

who cares if tar causes cancer or doesn't it will still fuck you up anyway, might as well eat a tire
