Medical marijuana will soon be available in chewable tablets, lozenges, and ointments under new regulations announced Thursday by the New York State Health Department. Only liquids, oils and vapors have been allowed under the state's tough restrictions that ban smokeable marijuana. The new rules, which could take effect next month, will also permit a doctor to take a two-hour course to become a registered provider, down from four hours. It's seen as a way to encourage more doctors to participate in New York's medical marijuana program.
