Cannabis supporters, buoyed by a series of small victories in Kentucky over the past two years, hope to use their momentum to legalize medical marijuana in Kentucky. Wednesday state lawmakers held their second public hearing this year on the issue, taking testimony from a quadriplegic who said marijuana eases his pain and treats his glaucoma. State lawmakers have already legalized industrial hemp farming and the use of hemp oil for medical treatment. State Agriculture Commissioner James Comer said lawmakers embraced the use of hemp for its economic opportunities as well as its medical benefits. Comer said he sees hemp as a new opportunity for family farmers. State lawmakers are planning at least two more public hearings on the medical marijuana issue this year before the legislature reconvenes in January.
