Almost everyone knows those who used marijuana at some point in their lives, and few claim that they have observed profound or lasting effects from the drug. So it cannot be that bad. After all, we live in a society that frowns upon cigarette smoking and has strict laws governing alcohol, so why not just legalize pot and allow a little fun?

Unfortunately, there are many studies available that attempt to demonstrate that marijuana use is harmless. Some states have legalized marijuana based on such data. However, there is a growing body of real scientific and medical studies that say the contrary. These make it evident that marijuana is hardly harmless.
