Over the last few months I have been hearing that weed kills braincells from nearly everyone I know that does not smoke and knows that I smoke. It's getting really annoying.

So can someone tell me if it does kill brain cells or not? Please this would be much appreciated.

Weed itself, does not. Smoke inhalation and oxygen deprivation, on the other hand, does. So does smoking cigarettes, so does drinking alcohol, so does playing a lot of sports, especially contact sports. A lot of everyday things have the potential to kill brain cells, but we're not all brain dead, why? Because we have billions of brain cells, and unless we're hitting our head against a wall often, there's not much to worry about.

I'm not real sure on it but,I don't beleive it kills braincells. My boyfriend has been smoking since he was 16 yrs. old and he's now 22. And he is very intellegent. So in my opinion I don't think it does.

Marijuana does not kill brain cells. It acts on recepters that your mind uses for sleep, does sleep kill brian sells?

EeJay is quite right with everything he said, and that the only way you could loose them is through oxygen deprivation.

And as for the remark that brain cells don't grow back, actually certain ones do. Some brain cells are able to grow one millimeter a day back, this is actually how stroke victems are, over a long period of time, able to gain back some function lost by a stroke.
That's not to say if you had extensive damage you would get it all back, but small amounts of damage can be repaired very easily. As well, your brain is able to compensate for _certain_ lost functions by using other neurons to replace them.

Oh, and by the way, age kills more brain cells than drugs ever will. After the age of 30 you loose about 30 brain cells per minute, so really, i wouldn't worry about the few marijuana doesn't even kill

Read this link, what you said is a myth.

Although I don't particularly support the theory that we only use 10% of the brain, the link you provided (i read the whole thing) does not do a good job of convincing me that we use more than that. It simply said that many people believe the 10% fact because they claim that "psychic endorsers" can use this arguement for their cause.

It then went on to say that fMRI and PET scans show that we "apparantly" use more throughout the day, with no actual link to a study, and nothing on particular effect or why.

I cannot believe this study, and in fact, i can give it no validility above and beyond the fact that it is someone's opinion.

Of course, the same goes for the "10% theory", so really all I'm left with is that we use "some amount of the brain, where nobody seems to know how much".

So is anybody who supports the idea that we only use 10% of our brain willing to undergo brain surgery and remove 90% of their brain (to see if they can still have normal brain function)?

well that wouldnt work since we don't know which 10% it is we supposedly use........ or do we???
