Marijuana: A Safe High

Length: 565 words

There are major claims about the effects of marijuana usage on people like it lessens the learning skills and impairs memory. While some experiment results state that cannabis has vital effects on such skills, according to some other researches cannabis has nothing to do with learning skills and losing attention. A comparison between students who smoked marijuana everyday with a control group that smoked every month showed that there is almost no difference between these two groups in terms of remembering some lists of words.

The fact that cannabis smokers do bad at school and work is because people who struggle to fit in the society tend to use marijuana more than regular people do. It is also proven that cannabis does not cause illnesses like schizophrenia and delinquency yet if people with such diseases smokes marijuana it might result in making them worse. Another claim is that people smoking marijuana are careless in traffic. Statistics show that in Britain and US accidents involving motorists marijuana smokers are very frequent.

Yet most of these motorists drank alcohol while they had the accidents. So we cannot mention a direct effect of marijuana on carelessness in traffic. A third claim is that smoking marijuana damages lungs and creates some aberrant lung cells. Again this claim is controversial. Anti-dope brigade says that a few joints are as hazardous as a packet of cigarettes while there are groups saying nobody has ever died of lung cancer because they smoked marijuana.

An experiment observing two groups, one who smoked 20 cigarettes a day and the other who smoked 3-4 joints of cannabis a day, showed that both these groups suffered from changes in the nuclei of their lung cells which may cause cancer and producing too many mucus-secreting cells. There are various reasons why 3 joints are equal to a packet of cigarettes in effect. First, joints have no filters and people smoking marijuana keeps the smoke after they inhaled in more than the cigarette smokers.

Also, the chemicals that cause cancer is richer in marijuana joints then the cigarettes. Despite this experiment, epidemiologists cannot find a direct relation between smoking marijuana and development of lung cancer. However there is one thing for sure; the immune cells of the people smoking marijuana are 35 per cent incapable of killing bacteria when compared to the immune cells of nonsmokers. The good news is for athletes. Unlike smoking cigarettes, smoking marijuana does not reduce the capacity of lungs.

There are six symptoms of marijuana addiction. One of them is that each time you need to smoke more to get the same effect. On contrast to nicotine, teenagers who smoke marijuana tend to get addictive more easily while people over the age 50 hardly become dependant . The final claim is that cannabis has some long-term effects on the brain just like the drugs of abuse. There are similar elements in marijuana and other drugs of abuse that start some chemical changes in the brain.

Varying symptoms have been observed in Marijuana users including anxiety and insomnia. However according to a university pharmacologist this does not mean that marijuana is as addictive as other drugs of abuse. The short term effect of marihuana supports this pharmacologist idea. Heroine and cocaine stimulates dopamine in brain. So does marihuana. Yet there are also non-addictive drugs that stimulate dopamine. So it is not easy to decide which category marihuana fits into.
