In contrast, studies in mice suggest that THC blocks this enzyme activity.<br><br>Another key difference, Melamede said, is in the immune system effects of tobacco and marijuana. Smoke sends irritants into the respiratory system that trigger an immune-regulated inflammatory response, which involves the generation of potentially cell-damaging substances called free radicals. These particles are believed to contribute to a range of diseases, including cancer.<br><br>But cannabinoids -- both those found in marijuana and the versions found naturally in the body -- have been shown to dial down this inflammatory response, Melamede explained.<br><br>Another difference between tobacco and marijuana smoking, he said, has to do with cells that line the respiratory tract. While these cells have receptors that act as docks for nicotine, similar receptors for THC and other cannabinoids have not been found.<br><br>Nicotine, Melamede said, appears to keep these cells from committing "suicide" when they are genetically damaged, by smoking, for instance. When such cells do not kill themselves off, they are free to progress into tumors.<br><br>THC, however, does not appear to act this way in the respiratory tract -- though, in the brain, where there are cannabinoid receptors, it may have the beneficial effect of protecting cells from death when they are damaged from an injury or stroke, according to Melamede.<br><br>All of this, he said, fits in with population studies that have failed to link marijuana smoking with a higher risk of lung cancer -- though there is evidence that pot users have more respiratory problems, such as chronic cough and frequent respiratory infections.<br><br>If marijuana does not promote lung cancer, that could factor into the ongoing debate over so-called medical marijuana. Melamede said he believes "marijuana has loads of medicinal value," for everything from multiple sclerosis, to the chronic pain of arthritis, to nausea caused by cancer treatment.<br><br>U.S. government officials, however, maintain that the evidence for medical marijuana is not there. Ten states allow people to use marijuana with a doctor's prescription, but the Supreme Court has ruled that federal law trumps state law.<br><br>SOURCE: Harm Reduction Journal, October 18, 2005. <p>--<br>When all else fails... panic.</p><i></i>

'''U.S. government officials, however, maintain that the evidence for medical marijuana is not there.''<br><br>no but the evidence for Saddams WMD's are, along with the yellowcake forged documents. How can anybody take anything these us government gatekeepers say seriously?<br><br>who can forget the kuwati incubator lies to start another war?<br><br>I find when a government department says something, to go the excat opposite and hey guess what, it proves to be spot on so far.<br><br>Kuwati incubators lies, complete opposite, no such thing.<br><br>Saddams WMD's complete oposite.<br><br>Yellowcake from nigeria, complete opposite.<br><br>Saddams mobile weapons labs, complete opposite.<br><br>Saddams WMD's heading my way in 45minutes, LOL, complete opposite.<br><br>The 'terrorists' are doing the bombing because they hate our freedoms. hehehe.<br><br>go on just try it the next time these government stage magicians issue another edict.<br><br><br>Many people smoke only herb, no tobacco. Birds eat it, whats the cancer rate in birds from eating that herb? I have known a couple of doctors smoking it too. Better keep it illegal, or else the alchol tax would disapear eh? <p></p><i></i>

wow, and all this time I thought it was only good for my <p></p><i></i>

<br> It didnt do my......it didnt do my......it didnt do my.... <p></p><i></i>

I was taught in school (of all places) that Marijuana, in and of itself has no permanent physical side effects if eaten by (adult) humans. <p></p><i></i>

I told you so <p></p><i></i>

I literally loved pot years ago- It made EVERYTHING better- sex, food, music, conversation; but damn, it sure messed up the rest of your day! <!--EZCODE EMOTICON START :hat --><img src=http://www.ezboard.com/images/emoticons/pimp.gif ALT=":hat"><!--EZCODE EMOTICON END--> <p></p><i></i>

Short term memory any good. <p></p><i></i>

whut? <p></p><i></i>

my academic performance and social skills increased slightly during my periods of experimentation.<br><br>The only memory lapses were "during" the experiments. I always assumed that was a good thing. Like a long road trip. What was there to remember anyway? <p></p><i></i>

I'll probably remember this conversation, 50 years on.<br><br>As for right now.. <p></p><i></i>

Whereas I'm really drunk, so I don't remember the beginning of this conversation. <p></p><i></i>

hmm, the original message here is best off published in another topic entirely...ever had that..lateral thinking happen? <p></p><i>Edited by: <A HREF=http://p216.ezboard.com/brigorousintuition.showUserPublicProfile?gid=robertdreed>robertdreed</A> at: 10/27/05 9:59 pm<br></i>
