Can marijuana permanently damage your brain?

Answer 1

Yes. Marijuana use can lead to permanent memory impairment. Frequent use results in loss of neurons in the area of the brain associated with forming memories and recall of memories. Users may also experience difficulty learning. Similar loss occurs in the aging population, thus marijuana use can be similar to accelerated aging of the brain.

Also, think of your natural state of contentedness when you are neither happy or sad. Following marijuana use, that point will be lowered, making your natural state of mind (mood) one that is more depressed. Heavy use can make this change a permanent one, and many people after quitting their marijuana habit, struggle with depression.

Frequent marijuana use has also been shown to contribute to the formation of amyloid plaque in the brain. This same plaque is known to be a main culprit in the brain disease known as Alzheimer's.

Also keep in mind that marijuana smoke contains 50 percent to 70 percent more carcinogenic hydrocarbons than does tobacco smoke... add to that, the fact that marijuana smokers inhale more deeply and hold their breath longer. This creates a serious danger for cancer of the head, neck and lungs.

Answer 2

yes, if you smoke it enough it will be permanent. They know it kills brain cells what they can't proove until you've done obvious damage is how much and how soon. You can probably get away with it a few times because God designed us in such a great way that we renew brain cells. It's like anything, if you are abusive it will not be renewed and you will be wondering qhat happened to you and where all your time went. Well, most pot heads that I knew were on the couch staring at the TV or laughing at the same old stupid jokes and not doing anything. Not a good legacy to yourself or your family or future. I hopw you don't let it take you that far. Good luck.

Answer 3

Marijuana causes short term memory loss, but not all of short term memory...some of them...

regarding permenant brain damage, i dont think so. Marijuana gives a relax status to your mind not destroying it...but if you smoke almost all the time, like a chimney then yes maybe tht will damage your brain. Everything tht is too much is not good.

Answer 4

Absolutley not. Your brain has cannaboid receptors similar to opium receptors for drugs like oxycotton and heroin. Cannaboid receptors work in the same way that your brain reacts naturally to the drug versus cocaine were it just adds chemicals to your brian to make you feel happy. However, smoking too much marijauan will eventually clog these receptors and untill you lighten up on smoking or just quit your brain will always be in a somewhat fog but never permanetly damaged.

Here's some interesting research results:

High Times for Brain Growth: Marijuana-like drug multiplies neurons
Christen Brownlee

In the stoner stereotype, pot smokers and dying brain cells go hand in hand. However, new research suggests the situation may be more uplifting than that. A drug that functions as concentrated marijuana does may spur neurogenesis, the process by which the brain gives birth to new nerve cells.

Previous research had suggested that neurogenesis happens only in select locations in the brain, such as the hippocampus, a region involved in learning and memory. Some studies have shown that this process is inhibited by most illicit drugs, such as cocaine, heroin, and methamphetamine. However, says Xia Zhang of the University of Saskatchewan in Saskatoon, marijuana's effect on neurogenesis has not been clear.

He and his colleagues started investigating this mystery by searching cell surfaces in live, cultured slices of rat hippocampus for receptors that respond to marijuana and a few other similar drugs, called cannabinoids. They reasoned that if marijuana affected neurogenesis in the hippocampus, then cells in that area must have a way to recognize the drug. Sure enough, 95 percent of hippocampus cells responsible for neurogenesis showed evidence of cannabinoid 1 (CB1) receptors, one of two receptors that respond to cannabinoid drugs.

Next, Zhang's team incubated samples of rat hippocampus with a solution containing HU210, a drug that stimulates CB1 receptors with a strength 100 times greater than that of pot. Other rat-hippocampus cells were incubated with the same solution minus the drug or with AM281, a drug that blocks CB1 receptors. After 2 days, the researchers found a significant increase in the number of new brain cells in the samples incubated with HU210, but no significant increase of such cells in the other samples.

Finally, the researchers injected adult rats with various doses of HU210. A single high-dose injection seemed to make no significant difference in the number of new nerve cells. However, animals injected with high daily doses of the drug over the course of 2 weeks had about 30 percent more newborn nerve cells than did rats given AM281 or a solution without either drug.

Animals given the 2-week course of HU210 also showed less anxiety and depressionlike behavior than did rats not given the drug. When the researchers irradiated the rats' hippocampi with X rays, which kill off new neurons, animals given HU210 responded to these tests much as did animals that didn't receive the drug. These results suggest that, while these new neurons probably don't increase intelligence, they could be responsible for antianxiety and antidepressive effects, says Zhang.

He and his team report their findings in the November Journal of Clinical Investigation.

Answer 6

Yes for some people I know some people that cannot remember there own name and some that are not right in the head always spacing out all the time.

Answer 7

Yes. The THC will clog up your synapses to the point where you have no short term memory whatsoever. You will forger what you are saying while you are saying it..You hang a coat up in a closet and forget where it is..You wont remember a name or a face...

Answer 8

People say it makes you forget. Let me tell you I don't believe a word of it . Now Whats the question? LOL

Answer 9

Ever seen the this is your brain, this is your brain on drugs commercial? It is true drugs eat your brain, BAD!!
