According to the Hearld Tribune, two years from now, Florida police may have a new category of impairment to consider: driving under the influence of a physician-recommended intoxicant. Assuming Amendment 2 passes on Nov. 4 allowing the use of medical marijuana in the state, residents would be able to treat a raft of conditions — ranging from cancer to glaucoma — with the plant. But legal or no, getting behind the wheel after using pot would still be a bad decision. Sergeant Robert Jovanovski of the Sarasota County Sheriff’s Office already is prepared. He has equipped many of his deputies with penlights and the training on how to spot marijuana users and how to question them during field sobriety tests.
