Smoking before bed kills lots of brain cells?

im not disagreeing(sp?) BUT i thought when you replace oxygen flow to ur brain with any kind of smoke it kills brain cells...thats what ive heard...prove me wrong cause i really wanna know

Smoke is solid, oxygen is a gas....one can't "replace" the other

Just tell your father that if he actually does his research, he will find NO credible study ANYWHERE that supports the idea that marijuana kills brain cells or "destroys your mind" (whatever that means). The government propaganda campaign has convinced lots of people that it does, but they're notorious for pulling facts out of their asses to scare the gullible masses.

Wow! Your father's a stupid cunt. Tell him to read a medical journal, then go fuck himself.

I'm sorry to say but your day is full of crap no way in the world does it give you brain damage or damage the brain cells at anytime little lone at bed time.I mean does he approve of you smoking?And has he shown you any medical reports/documentations,other than the white house reports?

Jamaican Cess- "smoke" is a mixture of vaporized tars and cannabinoids, particulate carbon, CO2, CO, and H20. The Vaporized tars are not exactly solid (more of a viscous liquid)m but the CO2, CO, and H20 are all gas. In fact, when you burn anything, the reaction combines the Oxygen in the air with whatever's burning, meaning the smoke you're pulling in has almost no oxygen in it.

Some of the early studies damning marijuana (think 1930's) were reexamined, and scientists realized all the damage being done was from Carbon Monoxide poisoning and lack of oxygen--but that was only because they pumped pure smoke and no air into gas masks for 5 minutes straight, which has the same effects as leaving your car running in a closed garage for about 5 minutes--not good. While this is only a small risk when smoking, it must be considered that every breath of smoke is, effectively, one breath of everything except oxygen.

However, the "before bed" part is bullshit.

I guess you didn't know that Oxygen only makes up for about 20% of the air that we breathe.

Intrepid... what are you talking about?! The breath of smoke replaces -everything- in -every- breath of air: nitrogen, oxygen, helium, hydrogen, everything. In fact, the combustion of the herb -consumes- oxygen. THe percentage of the air that is oxygen has nothing to do with it.

That was probably the most interesting post in this thread so far. Dudes, nobody wants to listen to so many facts or figures, nobody wants to hear "there is no credible evidence to support blah blah blah", seriously... If somebody was to say "weed turns people in to pedophiles" and you come back with "conclusive evidence actually show thats in five out of seven...." the other person's brain is just going to go "Shhhoooooooooommmmmmmmmmmmm" and switch off, and then go away still thinking the same things about weed that they were thinking before you ate their earhole off. All they remember is you spouting random facts and figures about something they know little about. This won't convince them about fucking anything. The way to deal with people who come out with all these myths and stories about what weed does to you is just tell them that they're wrong - if they argue just tell them that you know it to be true, and it's your words against theirs, and since they don't really know anything about weed then they oughta shut the fuck up. Sorry i'm stoned and I totally lost the thread of where this post was going.

Smoke displaces oxygen in your lungs, so make a hypothesis from that..........

Marijuana protects your brain
by Dana Larsen (01 Jan, 1999) Studies reveal that marijuana protects against brain damage from stroke, heart attacks, and nerve gas.


Illustration: Roddy Heading
The US National Institute of Health has found that chemicals in cannabis can reduce the extent of damage during a stroke, at least in rats.

Experiments with rat nerve cells, and then with actual rats, suggest that THC and cannabidiol, both compounds found in marijuana, can protect cells by acting as antioxidants, and could be useful in the treatment and prevention of stroke, heart attacks, and neurodegenerative diseases.

Researchers are investigating how cannabidiol and other antioxidants can reduce the severity of damage from "ischaemic strokes", in which blood vessels in the brain become blocked.

During ischaemic strokes, which make up 80% of all strokes, free radicals are released into the bloodstream. These harmful molecules are believed to cause stroke damage, such as paralysis and loss of speech and vision. Cannabidiol has potent anti-oxidant and anti-inflammatory properties, so it can neutralize free radicals and limit their damage.

Meanwhile, an Israeli pharmaceutical company called Pharmos is conducting human clinical trials using a synthetic, injectable version of cannabidiol, which they have dubbed Dexanabinol.

Dexanabinol's creator is Professor Raphael Mechoulam of Hebrew University in Jerusalem, who discovered THC in 1964, and has been studying cannabis for over thirty years.

Dr William Beaver, who chaired a panel assembled last year by the US National Institute of Health to review the medical uses of marijuana, called Dexanabinol "the most medically significant use ever made of marijuana."

The human clinical tests began in 1996 with 67 patients in Israel's neurotrauma centres. About 1000 patients will be involved in the next phase, at a cost of $15 million over two years. According to US medical investment analysts, Dexanabinol showed no serious side effects when administered to healthy volunteers.

Aside from the five million people worldwide who suffer a stroke or head trauma each year, there's another huge market for Dexanabinol, the US Army. US military tests on rats have shown that those exposed to Dexanabinol were 70% less likely to suffer epileptic seizures or brain damage after being exposed to sarin and other nerve gases. Dexanabinol is effective as both a preventative measure and as an antidote.

The military's greatest concern seems to be whether Dexanabinol possesses the same psychoactive and enlightening properties as THC and some other cannabinoids. Although THC and cannabidiol both provided equal defense against cell damage, cannabidiol doesn't have significant psychoactive effects.

Of course, the obvious corollary to this is that if synthetic Dexanabinol can prevent brain damage, then organic marijuana does so as well. So the next time grandpa has a stroke, try and get him to take a few bong-hits before the ambulance arrives. Better yet, give him a hash brownie each evening before he has that stroke. You might just save his life
