Reefer kills brain cells???

i think i remember reading a study done on rats that supposedly proved that thc was neurotoxic. however, if i recall correctly, they were giving the rats a constant dosage of pure thc for six months and in a dose somewhere around 200X a normal human dose by weight. doesn't seem like very realistic science to me.
 
^ from wut i read it isn't neurotoxic (and i've never come across any studies that have proven that it is...dunno about the one you mentioned)
 
Well it depends on how you look at it.
THC is definatly neurotoxic, but only defiantly so, to neurons grown in culture.

Whether its neurotoxic to cells in whole animals is a different, and debated issue.
 
why is THC definately neurotoxic?
Wouldn't anything be toxic at certain doses.. Just like H2O etc..

i think he just said that, definitely to cells in a culture. but you're right, most things are toxic to cells in a culture it seems.

and i'm going to try to find where i read that study. that was some proof, however unrealistic and unreasonable, that inhumanly high doses of thc are neuro-toxic in whole animals.
 
ya i think it does kill brain cells but doesn't necceseraly make u stupid i no someone who blazes everyday and hes on the honor roll and hes one of the smartest kids i no
 
im not a doctor or scientist, but i honestly dont thin so. if i had to shoot a guess, i think it just alters neurotransmitters in the brain after consistent use, thus causing memory problems etc. it is not a poison, like alcohol, so i dont think it kills brain cells
 
Zacamo, people have had a stroke and then gotten honors degrees. Are you gonna argue that strokes aren't neurotoxic?

Very reasonable doses are toxic to neurons in culture, and no, not everything is toxic to neurons in culture, although you are right to a degree, they are definitely more sensitive.

Of course the doses of THC that are needed to damage a mouse or a rat are higher than those given to humans, but that goes for pretty much all toxic chemicals.

I mean, the doses of THC they usually give to rats (10-20mg/kg) doesn't usually make them act in a noticeably different way, but that same dose would knock you out.

The real point is, we don't know, one way or another. The statistics are very inconclusive as to whether cannabis use effects in a (semi)-permanent way.
 
I don't have comprehensive knowledge of physiological toxicity, but from what I've read it would seem that weedobinoids are, if not completely non-toxic, at least a lot less harmful than they've been thought to be.
The relation of smoking weed and mental deterioration is, however, not as much about strict biochemistry as it is about context. If the ideas and values weed makes you express are the ones of watching tv all day (as presented in media, hm), we can all see that stupidity is inevitable :).
 
we only use ten percent of our brains power, mabey we have back up cells or a "cell regenerater" in the other 90% to replace the damaged/dead ones. just wanted to throw that into the mix
 
I just wish someone would do a good test in humans to see if abstinant heavy weed smokers have any cognitive impairments.

I mean, its so stupid, one of the big tests they did, which everyone thought was soooo good, let compared heavy weed smokers to light weed smokers. The prerequesit for being a heavy weed smoker was that you had cannabinoids in your urine (and in fact, the said on average they had smoked weed last, 30 hours ago). Well didn't those dumb doctors think, that maybe if they had balzed 30 hours ago, the THC in their system might be effecting them???

Fucking stupid doctors.
 
hahaha, plenty of studies on both sides. i'd say as soon as an absolute answer is found they'll be another study 2 yrs later to disprove it. you only live for about 78 yrs and out of the countless number of brain cells you'll damage or kill during this time i really dont think TCH is a drop in the bucket.
but then again no beer and no t.v. make homer something something.

Well Just after I wrote that last post, I found a very interesting article, which tested exactly what I said (i.e. that cannabinoids were still present) and after 28 days off the bud, all the people returned to a statistical norm.

Interestingly, although there was no STATISTICALY significant difference after 28 days of abstinance, the heavy cannabis smokers preformed worse on average than the light users on every single test measured...

Interesting stuff.

<EDIT> You can find that article , I hope...
here </EDIT>
 
Yeah and that "new car smell" is also supposed to kill brain cells.

Considering the vast amount of people who have been smoking in our culture for the past 40+ years, and the lack of a vast number of serious documented side effects as a result, I feel there is nothing to worry about.
 
Dude, people smoked cigarettes for about 200 years and no one noticed that they were bad for you until the 1950s. I mean, not that I'm argueing that smoke bud is as bad as cigarettes, but the fact that it won't be as bad, means that its going to be a fuck load harder to find if there are any negative side effects.

Wether weed kills brain cells or not, killing a few brain cells every once in a while is good for you. Take this analagy:

When a heard of buffalo gets attacked by some wolves, it is the slow and weak buffalo that get killed. This strengthens the heard. Hence, the periodic killing of the slow buffalo actually makes the heard stronger. The same is true for braincells, no?

dude...that is just not a valid argument. not even remotely.
 
So let's get this straight. Marijuana itself does not kill brain cells but smoking marijuana does? (the smoke kills brain cells).
 
smoking probably does, but thc is another thing. i don't really know, like everyone else said, a culture doesn't really help us. who knows. i don't really care to tell you the truth.
