hey guys i work and study in the area of medicine, and i also have more experience with recreational drugs than probably most people in my city. I dont use much at all these days, but my interests in drugs let me to study pharmacology, and my interests (and contacts
) in pharmacology led me to study more drugs, and from there i've gone into meicine, and for the most part had my fun with drugs and am now focussed on work etc.
anyway, the point i'm getting to is that no, weed is not good for you. In fact, in all my experiences with drugs (which include drugs that dont even have street names yet) i can probably say that weed is my *least* favourite. it just doesnt mesh with me. But for many of my friends it's their drug of choice, and it has an interesting culture surrounding it. Because it's so popular, especially amoungst people who "dont do drugs" (who consider weed not to be a drug) there is lots of misinformation out there about how safe and how "good for you" weed is, etc etc. I'm not going to get out my textbooks or anything, but here's the lowdown:
weed is not good for you. weed is bad for you. weed, however, is not as bad for you as many other things. Yes, weed can be beneficial to some people..but those people pretty much always have chronic illnesses, and the weed doesnt make them healthier directly, it is simply used to counteract some unhealthy side effects of their other treatments. (eg weed can be used to make cancer patients who have lost their appetite feel like eating again, etc)
the reason weed is bad for you is primarily because any hot particles that you are inhaling into your lungs aren't going to be good for you. Your lungs are not just big balloons; your alveoli (the things that expand and pass oxygen into ur bloodstream) have the form of broccoli sortof, and are amazingly thin and fragile. simply inhaling super hot air regularly would also be bad for you; having it filled with smoke just exacerbates the problem.
as for psychosis and whatnot, that is a much longer explanation and is dependant on many issues. to be stupendously succinct, research basically concludes that smoking pot cant give you schizophenia unless you are pre-disposed to it, however it can **** up your motivation, energy levels and lower level brain functions if you abuse the hell out of it and get high every day.
It is not addictive in the chemical sense; few substances are. but everything in this world can be addictive psychologically, (such as eating certain foods etc) and weed certainly falls into that category. As such, quitting weed after a really long time of heavy use can cause u some issues, BUT - and here is the important part: in terms of brain functions, unless you are pre-disposed to schizophenia, essentially all issues that weed can cause (lack of motivation, etc) will go away in time after you stop smoking (or eating) weed. but for the most part these issues are rarely a big deal anyway; we get more severe symptoms from breaking up with our girlfriends etc (another form of psychological addiction
so, in conclusion, weed isnt good for you. it hurts your lungs, because anything hot and filled with particles will hurt your lungs - they were made for air and air only. cigarettes are worse in the physical damage sense. In terms of mental damage, it's (usually, and i stress USUALLY) all temporary anyway, and not that severe unless you are getting permastoned for months on end.
finally, just to wrap up about diaz's comments on cigarettes, yes, people would still get cancer even without the chemicals. look at rolling tobacco, or even better, look at handmade cigars. they still give you cancer. maybe not as fast as tailormade cigs, but they still do. why? for the same reason i've said before, and so did someone else i think - any pariculate smoke that isnt air that is going into your lungs regularly is not good for you.
anyway i could do another giant post on why diaz's comments on pain pill were half wrong and half right, but i wont for now. i just figure that i love mma, but a lot of people here know more about it than me; so i mostly just read and rarely post. but when it comes to medicine, drugs or both, i figure i can at least contribute there, in order to give back some of all the education i get every day from reading everyone else's great posts on MMA.
thats all for now
