Granted, inhaling particulate carbon isn't great for your lungs, but it's nothing your lungs can't handle. Your lungs were designed to filter out airborne particulates-- thus coughing up phlegm. It's a natural response to the smoke, and it's only bad if you smoke so much that you no longer have phlegm to coat your lungs and throat.

That said, heavy smokers DO have an increased chance of lung infection--the article confirmed that. However, lung cancer is a whole different thing, and marijuana has been shown to be protective against lung cancer.

Finally, you're confusing evolution and Darwinian natural selection. Natural selection occurs over many generations through genetic mutation, but evolution can occur on a cellular level within a human. For instance, every time you get a virus, the body develops new antibodies to fight it off, and after that first sickness, you never get sick from that virus again--hence people only getting Chicken Pox once. That's evolution, plain and simple. As to whether your lungs actually get more resistant to smoke over time, I don't know, but don't rule it out as a flaw in evolutionary theory, because it's not.

To summarize, marijuana doesn't scrub your lungs clean, and it doesn't give you cancer. Certain effects are detrimental, and others are beneficial. To get the best of both worlds, don't smoke in excess, and only smoke good weed to avoid inhaling more smoke than necessary. Most of all, just enjoy being high!
Ok first of all natural selection results in evelution, i've been studying this for a year at uni so dont question me on it before u go and read even a high school text book! And i've explained the chicken pox thing and why it isnt evelution, it's a form of addaption.

Second smoking weed is very similar ot cutting yourself with a razor blade, and again please read through my earlier posts and give me a good reason why it isn.

lastly where on earth did u get the idea that you could run out of phlegm!?! it is the mucus lineing of your lungs and keeps getting produced when u lose it, this is a good thing but it takes time to regenerate it and during this time the chance of an infection or deadly carsonagenics getting into your lungs is a lot higher then normal. And there is no proof that weed provents cancer! there is a chance one chemical in it does but then what about the countless more! to put it in units: all the THC in one joint may provide 1 unit of cancer protection while all the other chemicals in that joint may provide 20 units of cancer, so once all the cancer proventions units are cancled out you still have 19 cancer units!

Another thing for all of you saying that weed cant kill you, remember that no one has ever dies directly from AIDS.
