Anxiety disorders are estimated to affect 18% of our population and cost over $42 billion a year in an attempt to alleviate symptoms and suffering. Many patients who are afflicted by anxiety prefer cannabis to prescription medications because it is an organically grown, fast acting medicine without the unwanted side effects of many prescription medications.
Cannabis is so effective at alleviating anxiety that it is hardly surprising that 44% of Americans aged 12 and older have reported having tried marijuana. Yet the American Medical Association has long denied any evidence of the medicinal value of cannabis, in spite of its popular widespread use, and for decades advocated a controversial legal synthetic THC pill which has lots of unwanted side effects, including anxiety itself! The AMA has only recently urged the DEA to end its criminalization of cannabis by reviewing its status as a class 1 controlled substance.
