Many proponents of marijuana claim that smoking it is less harmful than smoking cigarettes; however, this can be a disingenuous claim for several reasons. First of all, marijuana and tobacco are very different substances that have profoundly different effects on the body. Secondly, the process of smoking a drug can still have similar effects on certain parts of the body, such as the lungs and circulatory system, regardless of the drug type.
According to a study from the Journal of Adolescent Health, modern teenagers are very well informed about the dangers of smoking tobacco cigarettes. However, they have received a fair bit of misinformation about the effects of marijuana, and therefore, most often perceive it to be safer than it is, especially when compared to cigarettes and nicotine. To clear up some of the confusion about smoking, marijuana, tobacco, and health effects, it can help to provide a comparison of various elements of the drugs, how they are used, and how they affect physical and mental health.
