New York's first medical marijuana dispensaries are opening their doors on Thursday, as the state launches one of the most conservative programs of its kind in the United States.<br />The openings in New York come more than a year and a half after Governor Andrew Cuomo signed legislation, known as the Compassionate Care Act, that allow patients to use marijuana to ease their symptoms.<br />"Our program ensures the availability of pharmaceutical-grade medical marijuana products for certified patients and establishes strict regulatory controls to protect public health and safety," New York State Health Commissioner Dr. Howard Zucker said in a statement.<br />Unlike the all other states that allow medical marijuana, except Minnesota, the program prohibits marijuana for smoking.<br />In addition, New York requires a four-hour mandatory training course for physicians before they can certify patients, a requirement not mandated by other state programs, according to the National Conference of State Legislatures.
