I do know that Cannabis has been prescribed by the medical profession for YEARS under the name of Marinol.  It is concentrated THC.  It is given to patients with AIDS or cancer since it is one of the only drugs that not only helps combat nausea but INCREASE the appitite.  It does have side effects that undesireable such as paranoia and euphoria with some judgement impairments, but so far it is still a well used drug since it has been shown to be effective in keeping the patient's appitite up.  There is some drugs that are in the works that show promise in increasing the appitite, but as of now they are so expensive ($2000 a dose) that alot of doctors still prescribe marinol since it has a proven track record and is less expensive.

Marijuana is constantly in the news and more and more scientific evidence is pointing towards its use causing serious and permanent psychologically damage.\n\nOk!\n\nHow many people die from smoking cigarettes or from drinking themselves to death or other when these idiots try and drive etc?\n\nExcellent question!  \n\nAll three have very, very detrimental effects on our health and the health of others around us and it seems insane to 'point the finger' only at marijuana.\n\nAt the end of the day its your informed choice.\n\nRespect other, but do as you please!

Yes, the short term effects are:\nproblems with memory and learning\ndistorted perception \ntrouble with thinking and problemsolving \nloss of motor coordination\nincreased heart rate\nAnd, the users always think it has NO effects.  Yeah, right...denial at it's best.\n\nWould I want someone who is under the influence of weed to:\nfix my car\nbe my doctor\nbe my nurse\ntake care of my pets\ntake care of my kids\nbe behind me in a car\nor do anything that will impact my life or the lives of my loved ones? \n\nAbsolutely not!  They may not value my life or that of my loved ones but I do.

I have personally seen the positive results of marijuana therapy for a person undergoing radiation/chemotherapy treatments.  There are undoubtedly many who would benefit from using pot as a medicine, and I think it ridiculous that we enforce a law which prevents these persons from getting the help they so often are in need of.  Is it that dangerous as compared with alcohol, which is legal?  And if it were legal, do you really believe "every" kid and teenager would use it?  (As one person replied earlier) I SAY NO WAY. Let's make it legal for medicinal and many other uses, such as a building material and/or renewable energy resource!

Depends upon if you are looking for the positive for negative effects.  Nicotine affects the brain first, (nicotine is found naturally in vegetables to one degree or another) as the brain actually has receptors specifically for nicotine.  People with poor or damaged nicotine receptors find improved mental alertness and calmness in stressful situations.  Nicotine is also an anti-spazmodic, which is generally a brain/nervous sytem-related disorder, which is why it is helpful for people with MS, Parkinsons, IBS, and other spazmodic ailments.  Smokers are less likely to get communicable colds as the heat of the smoke and the nicotine combine to kill many germs and bacteria (organic gardners use a tobacco tincture to control pests and fungus).   The affects of nicotine to the brain are predominately positive.  The negative affects of smoking are more cumulative.  Smoking itself, particularly cigarettes, actually affects the teeth first (causing gum disease and rapid tooth decay), then affects the lungs second, and the heart and the cardio-vascular system a close third.  Smokers who never encounter lung or heart problems will always have dental problems.  The affects on the lungs are most serious, as lung transplants are frequently not an option, and there is no cure for lung cancer.  Diminished lung capacity also hurts the heart, muscles, skin, and organs as rest of the body as sufficient oxygen is not being pumped to all parts of the body.  What part of the body smoking will affect most will depend on three things:  genetic make-up (Recently, the oldest woman alive died after smoking since she was 12), other mitigating factors  such living and work environment, eating and exercise habits, general mental health, and how much smoking is done.

There was a very recent study that showed that marijuana use did not cause lung cancer as cigarette smoking did.\n\nThere are also studies showing that it reduces the pain of glaucoma and cancer, and because it increases appetite, it helps when cancer patients are going through chemo.

Male and female cannabis plants have equal amounts of the active biochemicals that have neurological effects in the brain. The main chemical is tetrahydrocannabinol (detlta 9). The story that only the female plants had active ingredient and the male plants had little is an urban myth. Some colleagues tested it by smoking from male and then female plants. Lest the narcotic police get upset, we had a Canadian government licence to grow the plants to collect the seeds for use in isolating certain elusive primitive water fungi that only grew on those seeds.(some Chytrids, Zygomycetes, & Oomycetes etc.)\nDoc Dan.

You get high and its the easiest way!\n\nPeople waste so much time in studies and work so hard to reach up a high point in their life, you are lucky you get high just smoking a pot of Ganja! \nIf i tell you it's bad you will ask for statistics, research studies and medical proofs. If i give all that , you have the right to refuse all the evidence. Its better that u continue and discover them urself

I'm only going to answer this because the person who said marijuana destroys brain cells is wrong. Marijuana in studies with ADULTS proved to cause minimum to NO damage in brain cells and or brain function. I'm friends with one of the most famous Pot doctors in the world and he has written a book that talks extensively about marijuana as a medicine for people EXACTLY like your friend.

Yes, only the ones wich arent bad for me. And only every once in a blue moon. But theres nothing wrong with a little mushroom or peyote, despite what they might have you believe. Speed and other uppers are terrible stuff, I would strongly advise against it. And pot is just in the same group as alchohol with me, only every once in a while. Its killed far less people than alchohol, even far less than asperin. People are just cattle sometimes, follow the propaganda and not thinking for themselves. Thats the only reason good drugs get a bad rap. I will say some people shouldnt do certain drugs though, not everyone knows how to handle themelves. But at the same time those people shouldnt do alot of other perfectly legal things either, like driving a car or having children. Oh well I guess, I mind my own business with it and dont harm a single soul.

Below, I have provided a link that will give you information on marijuana's effect on driving, on the heart, lungs, psychological aspects of marijuana use, etc.  I would've copied and pasted the WHOLE thing, but it's quite extensive.
