Marijuana. What Has Changed?

Recently 30 states accept marijuana in some form. 9 accept marijuana for recreational use, while 21 accept it for it's alleged "medical" use. However studies consistently affirm that marijuana, because of THC is an inhibitor to health both physically and psychologically. 

As recently at 2014 the US Dept. Of Health & Human Services reproduced the publication "Marijuana: Facts Parents Need To Know" outlining the dangers of marijuana. However, states, although making laws for those over 21, promote the drug and have made laws, even against federal guidelines in favor of the drugs use. According to recent surveys, Republicans are some of the primary proponents of the proliferation of marijuana. 

We ask, what is going on? What about science has changed that makes marijuana suddenly acceptable? As a culture and society, we need to take a serious and introspective look at what we are really doing and promoting.
