The first reason marijuana should not be legalized is that it leads to numerous health concerns for the user and those around him or her. Marijuana will increase the heart rate by 20% to 100% after using it and this can lead to later heart problems. It also affects the lungs and because when smoking marijuana, one inhales more deeply and for a longer time than when smoking cigarettes, so the effect on the lungs is even worse (“Marijuana” screens 1-2). It can lead to coughing, pulmonary infections, and lung cancer, and marijuana also represses the immune system, which exposes the body to numerous diseases (“What are the medical dangers of marijuana use?” screens 1-2). Finally, marijuana is very unhealthy for the brain. According to the web page “Marijuana” written by the National Institute on Drug Abuse, marijuana causes one to have distorted perceptions, impaired coordination, and problems with learning and memory. These results can last for multiple days.
