In the states where marijuana use is legal, strains of the drug are prescribed to cure chronic pain, anxiety, and epilepsy. A new study conducted by the University of Texas at Dallas has found cannabis can improve a person’s health by enhancing the blood and oxygen flow, thus reducing the risk of blood clots and the possibility of a stroke.” http://www.ibtimes.com/smoking-marijuana-can-reduce-risk-stroke-study-finds-2579489
