The benefits really outweigh the downsides for most people, especially once you find what works for you.

All drugs have side effects.  Pros/cons are a must for each consumer to evaluate.  The big deal is that America is realizing that MJ is not the same type of drug as cocaine, pcp, and meth -- the long term side effects appearing to be less damaging than alcohol, and the need for serious research exists to determine more facts about it.  It also demonstrated that prior generations used the war on drugs to target people of color disproportionately.; so the opening up of MJ markets have a significant social justice implication.
