Smoking before bed kills lots of brain cells?

[PotSm0key]

My dad told me not to get high before bed, he says it will destroy my mind :confused: this true? I know weed can kill brain cells, I mean everything does..but destroy my mind?

hes full of shit

[BluntManAndChronic]

weed makes u tired anyway

[Nullific]

SMOKING CANNABIS DOES NOT KILL BRAIN CELLS.
CANNABINOIDS HAVE BEEN SHOWN TO BE NEUROPROECTIVE.

NOT EVEN COCAINE OR LSD KILL BRAIN CELLS.

[OreO]

neway everthing kills brain cells...it doesnt make ur brain mush tho...

[shaggzx]

No, Marijuana does not kill brain cells, ever. Period.

[mellow mood]

YOUR DAD IS A LIAR!!!!

LOL

[OreO]

No, Marijuana does not kill brain cells, ever. Period.

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

[Zandor]

Brain cells die off all the time so he is right and he is wrong. It's a matter of how you look at it. Bedtime is a great time for a good buzz gives you good dreams.

[Budking]

I have a hard time sleeping sometimes so when i can't go to sleep, I just roll up a skinny and It puts me right to sleep like a baby :-)

[supersonicchronic]

Damn, is that why I'm so stupid? I get high and read myself bedtime stories all the time, usually improv. Once upon time Angelina Jolie sat on my lap and............................................... .................................................. .................................................. .................................................. ..............................

dont know, but if thats true then it proves that losing brain cells are nothing anyway, think how many people smoke cigs..

lmao, come on! tell us! lol

[Edd]

heading a football kills brain cells so i guess you shouldnt do that before you sleep?

[BUZz UK]

lol, come on potsmokey, think about it. why would smoking before bed make you lose any more braincells than smoking any other time? it's just bollocks mate, don't worry....

[partyguy420]

pot helps me sleep. lately i havent been smokin and i cant sleep at nite but i am going to get high over the weekend and it always helps me sleep

rule of thumb: if it sounds too impossible or stupid to be true, then it probably is. especially when dealing with drugs and authority figures.

(1) NO BRAIN DAMAGE SEEN IN MARIJUANA-EXPOSED MONKEYS

Two new scientific studies have failed to find evidence
of brain damage in monkeys exposed to marijuana, undercutting
claims that marijuana causes brain damage in humans.
The studies were conducted by two independent
research groups. The first, conducted by Dr. William Slikker,
Jr. and others at the National Center for Toxicological Research
in Arkansas examined some 64 rhesus monkeys, half of which
were exposed to daily or weekly doses of marijuana smoke for
a year. The other, by Gordon T. Pryor and Charles Rebert at SRI
International in Menlo Park, California, which is still
unpublished, looked at over 30 rhesus monkeys that had inhaled
marijuana one to three times a day over periods of 6 to 12
months. Neither study found evidence of structural or
neurochemical changes in the brains of the monkeys when
examined a few months after cessation of smoking.
The new results cast doubt on earlier studies
purporting to show brain damage in animals. The most famous
of these was a study by Dr. Robert Heath, who claimed to find
brain damage in three monkeys heavily exposed to cannabis.
Heath's results failed to win general acceptance in the
scientific community because of the small number of subjects,
questionable controls, and heavy doses.
Subsequent rat experiments by Dr. Slikker and others
reported persistent structural changes in the brain cells of
rats chronically exposed to THC. The studies did not show that
pot kills brain cells, as alleged by some pot critics, but they
did show degeneration of the nerve connections between brain
cells in the hippocampus, where THC is known to be active.
Although scientists have regarded the animal evidence
as inconclusive, some critics have cited it as proof that pot
causes brain damage in humans. Thus Andrew Mecca, the
director of California Department of Alcohol and Drug Abuse,
recently stated on the Ron Reagan, Jr. talk show (Sep. 2, 1991)
that marijuana "leaves a black protein substance in the
synaptic cleft" of brain cells, a claim apparently based on
Heath's monkeys. When asked by a NORML member for his
evidence, Mecca sent a list of three references, none of which
turned out to have anything to do with brain damage.
Although the new monkey studies found no physical
brain damage, they did observe behavioral changes from
marijuana. Slikker's group found that monkeys exposed once a
day to the human equivalent of four or five joints showed
persistent effects throughout the day. Slikker says that the
effects faded gradually after they were taken off marijuana,
and were not detectable seven months later, when they were
sacrificed. Autopsies did reveal lingering chemical changes in
the immune cells in the lungs of monkeys that had inhaled THC.
However, Slikker's group concluded that experimental exposure
to marijuana smoke "does not compromise the general health of
the rhesus monkey."

yeh zactly it wouldnt make a difference when you do it. i guess maybe psychologically but definitely not physically.

[JamaicanCess]

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

[ermitonto]

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.

[1e64102e]

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

[Miss Green]

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? :confused: :o

[Goodman3eb]

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.

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

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

[Goodman3eb]

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.

[GHoSToKeR]

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