There are many reasons why I believe marijuana should be legalized in the United States. One of the most prevalent reasons is the fact that tobacco has way more harmful effects to the body than marijuana does, however tobacco is legal. According to a study published in the Journal of the American Medical Association, researchers found evidence that marijuana does no harm to the lungs unless you also smoke tobacco, and additionally marijuana does not only doesn’t impair lung function, but it may even increase lung capacity in the long term. Personally, I have had experience of family members damaging their respiratory systems from smoking tobacco found in cigarettes. Health issues with your lungs could potentially be better avoided in the future if marijuana was as easily accessible to the public as tobacco is and becomes legal in all states.
