Every day, millions of Americans use illegal drugs. Among these dangerous substances is Marijuana. The issue of legalizing marijuana has become controversial and several people claim that marijuana does not cause any harm to users. Without realizing the long-term impacts this drug can bring, most people who support the legalization believe it is the right action to take. However, there are more reasonable arguments in the opposite perspective, backed by research, for people to consider. Marijuana should not be legalized in this great country of ours. It is a highly addictive drug that negatively affects its users including the teenagers both physiologically and psychologically. It destroys the relationships between people, harms users financially, and damages the functions of the government. Many people, especially teenagers, are not aware of the impacts that marijuana has on the human body. According to the National Institute on Drug Abuse (NIDA) website, these impacts of the drug are broken down in to physiological and psychological (“NIDA Infofacts”). Physiologically, marijuana can cause the failures of the important body parts including the lungs and the heart. In the heart, marijuana plays as a beat changer. Most marijuana users feel anxious, hyper, and exotic. Simply, one can explain why users feel those emotions. When users consume marijuana, the drug increases their heart rate from the normal level to a dangerous level. This increase in heart rate is not normal because it can later lead to heart attacks. It is crucial how marijuana can affect the heart of users, but it does not stop there. Marijuana also heavily affects the lungs of users. The NIDA website states that: "Numerous studies have shown marijuana smoke to contain carcinogens and to be an irritant to the lungs. In fact, marijuana smoke contains 50-70 percent more carcinogenic hydrocarbons than tobacco smoke. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increase the lungs' exposure to carcinogenic smoke. Marijuana smokers show deregulated growth of epithelial cells in their lung tissue, which could lead to cancer" (NIDA Infofacts). Marijuana also negatively affects sperm production in males and it can increase the size of the mammary glands. Psychologically, marijuana causes damages to the brain’s functions in prolonged steps. First, when a user smokes marijuana, he or she gets in the state of mind what one may call, “high.” When the drug gets into the user’s brain, it starts to destroy the brain’s receptors slowly with time. Consequently, the receptors become weak and impaired which causes the users to struggle with the way they think, memorize, concentrate, response, and feel; as well as the way people behave. In addition, the user may feel that time passes slower than usual. The user’s brain can also produce images and hallucinations that are non-existent (NIDA Infofacts). From the effects Marijuana has on the users both physiological and psychological, it is undoubtedly dangerous for people to consume this substance. Even though, some of the people see the danger the drug possesses, they still fight for its legalization. However, they don’t realize that the legalization can impair the future of the youths. It is easy for those in favor of the legalization of marijuana to say that it does not hurt anybody, but they are wrong. The legalization negatively impacts teenagers. Today, American teenagers are likely to get involved in many negative activities such as alcohol, sex, and drugs that interfere with their education and future. Teens favor these activities because they believe they can be part of something great based on popular culture. Therefore, when they see people around them doing marijuana, they feel stimulated since their minds are equipped to try a new thing which does not require a long period of time to get. As a result, they become too dependent on the drug. From the book, “Marijuana: opposing viewpoints,” the studies at the National Center on Addiction and Substance Abuse at Columbia University (CASA) shows that most teenagers can buy marijuana from a dealer within a day or sometimes an hour.
