Marijuana: THC Counters Cancer-Causing Chemicals?

A new report says that Marijuana is not a cancer risk since the THC acts to counter the cancer-causing chemicals produced by it's smoke unlike tobacco where the nicotine does the opposite. The report is by Dr Robert Melamede of the Univ. of Colorado.

"THC turns down the carcinogenic potential," he said stating that in studies on mice THC seems to block the enzyme that turns chemicals in smoke to their cancer promoting form. Also cannabinoids help to reduce immune regulated responses to smoke.

Cells in the respiratory tract have cells with receptors where nicotine docks but none have been found for THC or other cannabinoids. Cannabinoid receptors do appear in the brain where they may protect cells from death due to injuries like a stroke.

hmm very interesting

so wen do u think its goin b legalized

I don't it will becuase it will cut down on the pharmasutical industries money to much

ROFLMAO This is the most pathetic attempt by a professor to show pot having medical uses. Contrary to all the reports that show Pot smoke can cause cancer just like tobacco smoke

so what tholiak!i smoke 2 get HIGH jus like 99per of ppl.so they can say dii an dat but it aint gona make much diff 2 me or otheres 4 dat matter.if its not cancer its SARS if its not dat its fuckin bird flu all created by man from being unable 2 live clean!so if where gona die by hurricaines meteors disease i'll still b smokin d sacred herb its probably d only pure thing we have left.peace an love

This has been known about for a long time. Apparently with cannabis the cancer causing enzyme (p450 if I remember rightly) is still produced as it is with smoking tobacco but thc itself works in competition with said enzyme and protects the cells from being damaged. Of course this means that the higher the thc levels the greater the protection from harm as with skin cancer and head tumurs et al which unfortunately is getting bad press from the pharma companies quacks. :(

I heard of a report, not long ago, that claimed there are documented cases of lung cancer from marijuana - probably due to people growing it with soil containing carcinogen Polonium 210 - which has been present for a number of decades in the soil that tobacco is grown in.

I cannot locate that marijuana-Polonium report right now, but don't worry - there was no reason to believe that the problem is widespread. I forgot where it happened, but it was not in North America, or Europe.

In the meantime, here's some information about Polonium 210 and tobacco. A google search will yield more info.

â??Cigarette companies will have you believing
anything just as long as you continue to buy their products. The
fact is, although insoluble tars are a contributing factor to the
lung cancer danger present in today's cigarettes, the real danger
is radioactivity. According to U.S. Surgeon General C. Everette
Koop (on national television, 1990) radioactivity, not tar,
accounts for at least 90% of all smoking related lung cancer��..�

The pharmaceutical companies have just as much of a say in the legalization of marijuana, as a regular citizen does. There isn't a conspiracy there.
