问题     Marijuana(大麻) is a green, brown, or gray mixture of dried, shredded leaves, stems, seeds, and flowers of the hemp plant ( Cannabis sativa). Cannabis is a term that refers to marijuana and other drugs made from the same plant. Other forms of cannabis (大麻) include sinsemilla. hashish and hash oil. All forms of cannabis are mind-altering (psychoactive) drugs.
    The most common way of using marijuana is smoking. Smoking is also the most expedient way to get the THC (a main active chemical in marijuana) and other chemicals into the bloodstream-- when the smoke from marijuana is in haled, the THC goes directly to the lungs. Your lungs are lined with millions of alveoli, the tiny air sacs where gas exchange occurs. These alveoli have an enormous surface area--90 times greater than that of your skin--so they make it easy for THC and other compounds to enter the body. The smoke is absorbed by the lungs just seconds after inhaling.
    You can also eat marijuana. In this case, the marijuana enters the stomach and the blood absorbs it there. The blood then carries it to the liver and the rest of the body . The stomach absorbs THC more slowly than the lungs. When marijuana is eaten, the levels of THC in the body are lower, but the effects last longer and are more deteriorating.
    Marijuana users often describe the experience of smoking marijuana as initially relaxing and mellow, creating a feeling of haziness and light-headedness. The user’s eyes may dilate, causing colors to appear more intense, and other senses may be enhanced. Later, feelings of a paranoia and panic may be felt by the user. The interaction of the THC with the brain is what causes these feelings. To understand how marijuana affects the brain, you need to know about the parts of the brain that are affected by THC.
    The debate over the addictive capacity of marijuana continues. Ongoing studies now show a number of possible symptoms associated with the cessation of marijuana use. These symptoms most commonly include: irritability, nervousness, depression, anxiety and even anger. Other symptoms are restlessness, severe changes in appetite, violent outbursts, interrupted sleep or even insomnia. In addition to these possible physical effects, psychological dependence usually develops because a person’s mind craves the high that it gets when using the drug.
    Beyond these effects that marijuana has, marijuana smokers are susceptible to the same health problems as tobacco smokers, such as bronchitis, emphysema and bronchial asthma. Other effects include dry-mouth, red eyes, impaired motor skills and impaired concentration. Long-term use of the drug can increase the risk of damaging the lungs and reproductive system, according to the US Drug Enforcement Agency (DEA). It has also been linked to heart attacks.
    Although marijuana is known to have negative effects on the human body, there is a raging debate over the use of medicinal marijuana. Some say that marijuana should be legalized for medical use because it has been known to suppress nausea, relieve eye pressure, decrease muscle spasms, stimulate appetite, stop convulsions and eliminate menstrual pain. Because of its therapeutic nature, marijuana has been used in the treatment of several conditions including: cancer and AIDS (to suppress nausea and stimulate appetite), glaucoma (to alleviate eye pressure), epilepsy (to stop convulsions) , and multiple sclerosis (to decrease muscle spasms).
    Others believe the negative effects of marijuana usage outweigh the positive. There are currently several US states that have legalized marijuana for medical purposes Alaska, Arizona, California, Colorado, Hawaii, Maine, Nevada, Oregon and Washington.
