Marijuana should be legalized because of the false ideas that made it illegal. One false idea that made it illegal is the idea that marijuana kills your brain cells. In 1974, there was a study done, the “Dr. Heath/Tulane Study”. After the study Ronald Reagan announced “the most reliable scientific sources say permanent brain damage is one of the inevitable results of the use of Marijuana”. The study used monkeys pumped full of marijuana, apparently thirty joints a day, began to atrophy and die after ninety days. It was determined that they suffered brain damage after counting the dead brain cells of both monkeys that had been tested with marijuana and ones who had not. This study became the foundation for the government and interest groups to say that marijuana killed brain cells. Now here is why it’s a false idea. It was revealed how the study was conducted nearly after 6 years of requests. Instead of pumping 30 joints a day for 1 year, Dr. Heath used the method of pumping 63 joints through a gas mask within five minutes over three months. They also did this without adding any additional oxygen, so they were being suffocated with marijuana smoke. When someone suffocates, brain cells will start to die because of lack of oxygen. According to the St. John Ambulance – First Aid Guide,”4 minutes without oxygen, brain damage may result”. So after they suffocated the monkeys and went on to associate and said that the use of cannabis causes brain cells to die. So this idea became so infused in America’s society because no one really knew the origin of the study. Another false idea created that helped make marijuana illegal is: it gives you lung cancer. In the 1999 by the Institute of Medicine (which was paid for by the United States Government), they had to use words such as “may” or “should” cause cancer. There is not one case out there that shows cancer being caused by cannabis use alone. The chances of cannabis causing lung cancer are slim because cannabis is not radioactive. Now smoking can be harmful because of the properties of smoke, not because of anything in the cannabis plant, but because people are taking in heated plant matter into their lungs. “The National Institutes of Health’s National Institute on Drug Abuse funded the University of California at Los Angeles study, which found that smoking marijuana does not cause lung cancer, and it doesn’t seem to matter
