Can you give me some examples of ceonceptual framework on marijuana?

I thought that conceptual frameworks were for systems and/or processes, marijuana is neither...\n\nAre you looking for a conceptual framework on the *use of* marijuana?  Casual or Habitual?

Yes, there is ...\n\n\nMarijuana: Don't let your health go up in smoke\nMarijuana use isn't the harmless habit some believe; it may contribute to serious health problems. \nMarijuana is the most commonly used illicit drug in the United States — nearly 15 million Americans currently use it. People generally smoke marijuana, which consists of the leaves, flowers, and other parts of the Cannabis sativa plant, but they may also consume it as an ingredient in food or drink.\n\nThough some people take the drug because of medical problems, marijuana users generally smoke it for the high it produces. The high is the result of a component in the plant, called tetrahydrocannabinol (THC) — one of a group of 60 or so chemicals in the plant called cannabinoids. The high from smoking marijuana usually creates a dream-like feeling of euphoria and relaxation. However, not all its effects are so dream-like. If you use marijuana or you're considering using it, know that it may cause a number of health problems, from memory loss to cancer.\n\nEffects on your mind and brain\nMarijuana can cause you to lose track of time and to feel sluggish and forgetful immediately after using it. The drug may also:\n\nReduce memory. Marijuana can inhibit short-term memory, interfering with your ability to learn and remember bits of information. \nInhibit driving ability. The drug can reduce eye-hand coordination, reaction time and muscle strength. Coordination and movement impairment can last hours after you no longer feel high, endangering you and others on the road if you're driving. A 1991 study of airplane pilots shows that pilots who smoked marijuana fared worse on simulated aircraft landings — combined with a lack of awareness of the poor performance — even 24 hours after smoking marijuana. \nLimit attention span. With daily marijuana use, you may have trouble maintaining attention, shifting attention from one subject to another and processing incoming information for many hours after you last used the drug. \nIncrease risk of schizophrenia. Marijuana use has been strongly associated with an increased risk of this mental illness — a form of psychosis that results in abnormal interpretation of reality. \nGenerate unpleasant emotions. The drug may cause paranoia, anxiety and panic during use. Such symptoms usually fade as the drug wears off. \n\nMORE ON THIS TOPIC\nSchizophrenia and drug abuse: Are they related? \n\nHard on your heart\nSmoking marijuana can quickly cause your heart to beat 50 percent faster than normal, which can put people who already have poor blood flow at increased risk of chest pain (angina) or even a heart attack. It can also affect your:\n\nBlood pressure. Your blood pressure may increase immediately after using marijuana, which could increase your risk of a stroke if you have cardiovascular disease. Conversely, the drug can also decrease your blood pressure to a point that's too low, making you dizzy and lightheaded. \nBlood flow. Using the drug can decrease blood flow to your heart. This is particularly dangerous if you already have poor blood flow due to coronary artery disease, in that it could set the stage for a heart attack. \nExercise ability. If you have angina, marijuana use can reduce your ability to exercise as vigorously and can make your heart rate rise earlier during the exercise session, causing you to suffer chest pain earlier during your exertion. \nBreathing less easy\nUnlike cigarettes, marijuana joints don't have filters, and you typically inhale the smoke deeply, holding it in before exhaling — which means you could expose yourself to dangerous components in the smoke for longer periods of time. Possible respiratory problems include:\n\nCancer. Burning marijuana smoke contains higher amounts of some cancer-causing chemicals than does tobacco smoke. Smoking marijuana increases your risk of cancer of the mouth, larynx and lungs. \nBreathing trouble. Long-term marijuana use incre

Marijuana has been used for centuries in many religious practices, it is only in modern times it has been outlawed. I think Rastafarians are still allowed to use it for religious purposes though.

Happy 420!  I use marijuana for treating depression. It also helps with anger management. I have had success in using it as a pain reliever.

Agree, at its worst marijuana is as bad for you as cigarettes and alcohol, both of which are legal. Its not up to the government what we decide to do with our bodies or our free time. You would have a hard time making a case that personal consumption of marijuana hurts anyone other than the smoker.

Effects on the Brain\n\nScientists have learned a great deal about how THC acts in the brain to produce its many effects. When someone smokes marijuana, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to organs throughout the body, including the brain.\n\nIn the brain, THC connects to specific sites called cannabinoid receptors on nerve cells and influences the activity of those cells. Some brain areas have many cannabinoid receptors; others have few or none. Many cannabinoid receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement4.\n\nThe short-term effects of marijuana can include problems with memory and learning; distorted perception; difficulty in thinking and problem solving; loss of coordination; and increased heart rate. Research findings for long-term marijuana abuse indicate some changes in the brain similar to those seen after long-term abuse of other major drugs. For example, cannabinoid (THC or synthetic forms of THC) withdrawal in chronically exposed animals leads to an increase in the activation of the stress-response system5 and changes in the activity of nerve cells containing dopamine6. Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse.\n\n\nEffects on the Heart\n\nOne study has indicated that an abuser's risk of heart attack more than quadruples in the first hour after smoking marijuana7. The researchers suggest that such an effect might occur from marijuana's effects on blood pressure and heart rate and reduced oxygen-carrying capacity of blood.\n\n\nEffects on the Lungs\n\nA study of 450 individuals found that people who smoke marijuana frequently but do not smoke tobacco have more health problems and miss more days of work than nonsmokers8. Many of the extra sick days among the marijuana smokers in the study were for respiratory illnesses.\n\nEven infrequent abuse can cause burning and stinging of the mouth and throat, often accompanied by a heavy cough. Someone who smokes marijuana regularly may have many of the same respiratory problems that tobacco smokers do, such as daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, and a greater tendency to obstructed airways9. Smoking marijuana possibly increases the likelihood of developing cancer of the head or neck. A study comparing 173 cancer patients and 176 healthy individuals produced evidence that marijuana smoking doubled or tripled the risk of these cancers10.\n\nMarijuana abuse also has the potential to promote cancer of the lungs and other parts of the respiratory tract because it contains irritants and carcinogens9,11. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than does tobacco smoke12. It also induces high levels of an enzyme that converts certain hydrocarbons into their carcinogenic form—levels that may accelerate the changes that ultimately produce malignant cells13. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which increases the lungs' exposure to carcinogenic smoke. These facts suggest that, puff for puff, smoking marijuana may be more harmful to the lungs than smoking tobacco.\n\n\nOther Health Effects\n\nSome of marijuana's adverse health effects may occur because THC impairs the immune system's ability to fight disease. In laboratory experiments that exposed animal and human cells to THC or other marijuana ingredients, the normal disease-preventing reactions of many of the key types of immune cells were inhibited14. In other studies, mice exposed to THC or related substances were more likely than unexposed mice to develop bacterial infections and tumors15,16.\n\n\nEffects of Heavy Marijuana Use on Learning and Social Behavior\n\nResearch clearly demonstrate

Marijuana is not physically addictive. Psychological dependency is common: this means that a user will want to use MJ again, because they like the way it makes them feel, although there is no persistent chemical change in the brain.\n\nThe recovery potential should be looked at as part of improving the whole life and surroundings of the user.\n\nTreat the circumstances that make the user want to get stoned, and you might break the user's habit. Finally, though, the choice is with the person using the MJ, and unless the user is a minor or otherwise under guardianship, that choice can't be made on their behalf.

Well Mathyu I wish you could grow your own legally. I would be growing my own legally too if I could. I just went to Jack Herer's website and will be spending some time later reading more of it. Previously I was unaware of cannabis' ability to turn back the hands of time for Alzheimer's patients. My mom died of complications from Alzheimer's Disease I wish I had known then that there was a way to help her to keep from losing parts of herself.\nI could certainly use the $ but I don't think from what I've read so far that I would want to prove Jack wrong.\nWe'll talk again I'm sure.\nLL

Can you give an example like : "For example, the use of corn and soybeans as a gasoline additive shows promise for reducing fossil fuels which will make the country safer and cleaner."

marijuana is only *psychologically* addictive, not *physically* addictive. caffeine and alcohol are *physically* addictive (i.e. if you're addicted, you will experience withdrawal, increased tolerance, and essentially, your body physically needs the drug to function). \n\nmarijuana is only addictive in the sense that your brain will slowly adjust to repeated use of the drug, causing stuff like "amotivational syndrome" (exactly what it says - you become lazier).\n\nthe short-term effects, essentially, are that you get high. slower reflexes, sensitivity to touch and light, the whole deal. the more you have, and the more THC is in the dose, the stronger the effects. it affects your driving ability significantly. \n\nit is physically impossible to overdose on marijuana.\n\nlong-term effects are purely psychological - but there are some other issues. marijuana is a very popular gateway drug - i.e. teenagers will try it, think it's cool, and use it as a "gateway" to harder drugs, like ecstasy, cocaine, heroin... which are all highly addictive and easy to overdose on.\n\nyou can obviously get lung cancer and stuff from marijuana, but notably, studies show that you can't get emphysema from marijuana.

Marijuana is a vasodiolator(causing the blood vessel to open and allow the blood to flow freely) This is why it is prescribed sometime for use in treating migraine headaches. Of course any idiot knows that if something hurts QUIT DOING IT.

you can't....that's why it is called the marijuana effect....the effect is from THC (tetrahydra cannibinal), so to get the effect, you'd need THC and that, my friend, is illegal....just smoke on, man, those tests at the parole officer's office are a joke...

I think mainly the overuse of marijuana causes depression. It is a depressant, but thats like alcohol too, that causes depression but you'd hardly be aware of it if you didnt use it all of the time (like daily)
