Poppycock.  Marijuana is proven to be safe enough to allow adults to make an educated choice about using it or not.  Isn't that what social Conservatives such as yourself want?  Personal responsibility over government mandates?

Yoga moms juggling their coffee, cell phones and children in their autos cause more harm than people that have smoked a joint.  No, tobacco smokers aren't admitted to psychiatric wards any more than the normal population; they tend to go directly to the cancer wards and hospices.  If fact the majority of people in the cancer wards have a history of smoking tobacco.  Such a costly burden on society.

You obviously don't like marijuana, so you personally don't have to use it.  Easy eh?
