The problem with marijuana is that it alters your sense of space and time. You might have fantastic idea's when you're stoned. However once you return to a normal unaltered state of mind your perception on theses ideas will have changed also. As for higher analytical  skills. I would say NO! analytical skills require a brain that has the ability to remember things immediately instead of a few hours later. \n\nGood luck and dont waste to much time thinking about it!

It can mess with your head(well duh) but I mean more than just at the moment.  It can cause or make depression worse, it doesn't cause mental disorders but can make them worse.  It kills motivation, causes cancer, causes impotence.  Its emotionally addicting, which can be just as bad as a physical addiction.  What you really have to think about is why do it in the first place, there aren't many reasons to smoke pot other than at the moment it feels good, but there are a lot of reasons not to.  I have smoked pot for years, and honestly I wish I had never started.  I wonder where my life would be if I hadn't.

All forms of marijuana are mind-altering. This means they change how the brain works. They all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. But there are also 400 other chemicals in the marijuana plant.

Male and female cannabis plants have equal amounts of the active biochemicals that have neurological effects in the brain. The main chemical is tetrahydrocannabinol (detlta 9). The story that only the female plants had active ingredient and the male plants had little is an urban myth. Some colleagues tested it by smoking from male and then female plants. Lest the narcotic police get upset, we had a Canadian government licence to grow the plants to collect the seeds for use in isolating certain elusive primitive water fungi that only grew on those seeds.(some Chytrids, Zygomycetes, & Oomycetes etc.)\nDoc Dan.

The major active chemical compound tetrahydrocannabinol, commonly referred to as THC, has psychoactive and medicinal effects when consumed.Medically, cannabis is most often used as an appetite stimulant and pain reliever for certain terminal illnesses such as cancer and AIDS.It is used to relieve certain neurological illnesses such as epilepsy, migraine and bipolar disorder.It has also been found to relieve nausea for chemotherapy patients. The medical use of cannabis is politically controversial, but it is sometimes recommended informally by physicians. A synthetic version of the major active chemical in cannabis, THC, is readily available in many countries in the form of a pill as the prescription drug dronabinol (Marinol). THC has also been found to reduce arterial blockages.A sublingual spray derived from an extract of cannabis has also been approved for treatment of multiple sclerosis in Canada as the prescription drug Sativex [3] - this drug may now be legally imported into the United Kingdom and Spain on prescription.\nTherapeutic effects -\nPain relief (especially headaches, cramps, and eye pain due to lowered intraocular pressure). \nIncreased appetite, food subjectively tastes better. \nReduced nausea, (especially from chemotherapy), though may cause or exacerbate nausea for some. \nDilation of alveoli (air sacs) in lungs, resulting in deeper respiration. \nIncrease in productive coughs \nDilation of blood vessels (vasodilation), resulting in: \nIncreased blood flow and heart rate \nReddening of the conjunctivae (red eye) \nLower intra-ocular pressure (beneficial to glaucoma patients). \nLower blood pressure while standing. Higher blood pressure while sitting (note that this can lead to instances of orthostatic hypotension a.k.a. head rush). \nInduces drowsiness (beneficial to sufferers of insomnia and sleep deprivation). \nRelaxation \nReduced stress \nMild entheogenesis

Hallucinogenic drugs cause both physical and psychological effects on humans. The physical effects of these drugs include: dilated pupils, elevated body temperature, increased heart rate and blood pressure, appetite loss, sleeplessness, tremors, headaches, nausea, sweating, heart palpitations, blurring of vision, memory loss, trembling, and itching. A user of hallucinogenic drugs will also experience a number of psychological alterations in the brain. These drugs may cause hallucinations and illusions as well, as the amplification of sense, and the alterations of thinking and self-awareness. It is quite possible to have a bad reaction to hallucinogenic drugs. This is referred to as a "bad trip" and may cause panic, confusion, suspicion, anxiety, and loss of control. The long-term effects of these drugs can be quite dangerous. These long-term effects may include: flashbacks, mood swings, impaired thinking, unexpected outbursts of violence and eventually possibly depression that may lead to death or suicide.

I'm only going to answer this because the person who said marijuana destroys brain cells is wrong. Marijuana in studies with ADULTS proved to cause minimum to NO damage in brain cells and or brain function. I'm friends with one of the most famous Pot doctors in the world and he has written a book that talks extensively about marijuana as a medicine for people EXACTLY like your friend.

Long-term physical effects of smoking marijuana;\nIn some ways, the effects of smoking cannabis are similar to the effects of smoking any substance. Any time you inhale smoke, the respiratory system is adversely affected. These effects are particularly apparent with repeated and prolonged use. Studies have pointed out that cannabis produces more tar and burns at a higher temperature than tobacco. Some cannabis smokers inhale the smoke more deeply and hold it in their lungs for a longer period of time. However, the average cannabis user smokes less frequently, and there is evidence that cannabinoids present in cannabis may actually serve to protect against cancer. http://ehp.niehs.nih.gov/docs/2000/108-10/correspondence.html#thc Furthermore, the concentration of toxic and carcinogenic additives such as nicotine, arsenic, and radium-226, is substantially greater in tobacco cigarettes than in cannabis.Medically, cannabis is most often used as an appetite stimulant and pain reliever for certain terminal illnesses such as cancer and AIDS. It is also used to relieve glaucoma and certain neurological illnesses such as epilepsy ,migraine and bipolar disorder. The medical use of cannabis is politically controversial, but it is sometimes recommended informally by physicians. A synthetic version of the active ingredient in cannabis, THC, is readily available in the form of a pill as the prescription drug Marinol. THC has also been found to reduce arterial blockages.http://www.nature.com/news/2005/050404/full/050404-7.html A sublingual spray derived from an extract of cannabis has also been approved for treatment of multiple sclerosis in Canada as the prescription drug Sativex.

It takes one time to screw up your whole brain. I don't know if you know this but it's side effects include rapid heart beat, muscle tension, insomnia and headache. Research has found that MDMA is neurotoxic, meaning it can cause damage to the nervous system which includes the brain. Ecstasy, in its pure form, does not contain heroin - though one never knows what street drugs really contain. Many tests have been done which show that MDMA damages certain neurons in the brain that release a chemical called seratonin (5 HT hydroxytryptamine). This chemical controls emotions, sleep, appetite, memory and reasoning. Brain scans were also done to people who had used Extacy 200 times in five years. The scans showed there to be major brain damage in these patients, and scans also showed that these damages got worse as the user took more Extacy.Also, a recent autopsy on a heavy user of \nExtacy found there to be 60-80% less seratonin in his brain.

because the thc in marijuana opens up the blood vessels making them less constricted, and the oxygenated blood in the cappilaries becomes more prevelant in the eyes, which is the same reason why people with glaucoma(acute constricting of blood vessels in the eyes) use marijuana for their condition.

Both can cause damage to the brain with heavy use over long periods of time, although it's much, much worse with alcohol.  Prolonged alcohol abuse will also damage the liver, while heavy marijuana smoking can cause forms of lung damage also caused by cigarette smoking.  So irresponsible use of either carries some health risk.\n\nBut it's very clear that alcohol abuse is much more likely to cause severe, irreversible, often fatal health effects than even the heaviest use of marijuana.  In theory, marijuana smoking could cause lung cancer in some people, but this is certainly very rare if it happens at all.  In contrast, the number of people in the U.S. who develop dementing brain damage (sometimes called "wet brain") or fatal liver disease, as a direct pharmacological effect of years of heavy drinking, is in the thousands.  Indirect damage (i.e. not pharmacological) to the user or others is also much more frequent with alcohol abuse than with pot smoking, given that alcohol is involved in approximately half of all motor vehicle fatalities, small aircraft crash deaths, drownings, fatal burn injuries, falls, homicides, suicides, and non-fatal injuries as well.  Marijuana smoking may be associated with some number of fatal and nonfatal injuries, but that number is probably very small.  \n\nAs if all that didn't make for a vivid, persuasive comarison favorable to marijuana, its also certain that the amounts of social, psychological, and spiritual damage associated with alcohol vastly exceed those possibly linked to pot smoking. "Reefer Madness" turns out to have been just a bad movie, and I suspect that intelligent space aliens would be astounded to discover a supposedly rational society in which alcohol use is accepted and promoted while marijuana smokers fill up jail cells.  I'm not suggesting, of course, that  there aren't good reasons for discouraging irresponsible use of alcohol OR marijuana by anyone, and children and adolescents should, in my view, be discouraged from using them at all even if both were legal for adults.

Hats of my fellow well informed freedom fighting friend , most recent studies have shown that Marijuana doesnt destroy any ,,ANY , of your brain cells and in fact a harvard study shows that students who used canabis in moderation while studying for exams were more analetic and scored higher averages than those who didnt . but people are still very ill informed on the real facts . the brain cell killing lie came about without any real studyies and is a product of govermental lies .

Yes, cannabinoids and endorphins are made in the brain.\n\nCannabinoids help you forget pain, and endorphins prevent you from feeling pain in the first place.
