So what? By this reasoning, alcohol, caffeine, tobacco, fatty foods, lead ammunition and firearms with an audible report above 90 Decibels should all be regulated. After all, do these not cause one harm?
Sheesh, of course ... I agree!
Originally, the ONLY point I was attempting to counter was the statement that marijuana was "a harmless weed." The only point I was attempting to make was that, yes, there are harmful effects associated with regular marijuana smoking, and that many of these effects are well-documented.
Old Dog, I'm sorry, but this is not only a cop-out, it is also extremely poor form.
Oh, for heaven's sake. I could easily provide links to about 469,000 websites that discuss research on the harms of marijuana, the use of marijuana in medicine and marijuana law reform. However, one tap on the Google search button for "marijuana harm" will get you those 469,000 links. As I'm presently not at the library, I can't quote chapter and verse of some of the more esoteric research published in, among others, the Journal of the AMA and numerous, respected scientific and medical publications.
If people want to deny there are any harmful effects of pot smoking, or tout the wonderful benefits to society of pot smoking, that's fine by me; go for it. But debating whether or not there exists actual medical and scientific evidence possibly documenting harmful effects of marijuana, and expecting me to "prove" this is something I simply don't have time for today.
Here's one good link:

Also, one should check out the seminal study done on medical marijuana use,
