There are certainly some major generalizations in this thread. There are so many variables with each individual and their personal experiences with marijuana or around marijuana users it's hard for me to claim such strong opinions on the matter. Beliefs are often a result of an individuals perspective. Often times that perspective was likely skewed from some sort of biased environment from what was believed to be trusted sources. This subject is so extensive and contains so many viewpoints it makes for muddy waters in argumentation. Their are a lot of people that use marijuana responsibility and it has a positive benefit to their lives. Their are a lot of people who also abuse it and it adds negative benefactors. Let's remember to keep in mind that a lot of obese people also abuse cheeseburgers and milkshakes. Perspective is important.
