Stress is defined by the Merriam-Webster Dictionary as “a physical, chemical, or emotional factor that causes bodily or mental tension and may be a factor in disease causation.” It has been dubbed the “silent killer” and is linked to six leading causes of death: heart disease, cancer, lung ailments, accidents, cirrhosis of the liver and suicide. When stress begins to affect your health, the most common and immediate recommendation given by doctors is to get rest and relaxation.

Medicinal cannabis is a form of herbal therapy that can be traced back thousands of years. Presently, several countries and over 50% of states in the U.S. have legalized medicinal cannabis. Medicinal cannabis is highly effective in relieving stress and can also be used to treat nausea, pain, and numerous other symptoms associated with many illnesses. Medicating with medicinal cannabis is unique in that it can be a social activity enjoyed with company or a personal, sometimes spiritual experience that can enhance relaxation and/or being in the moment.
