Doctors face new rules for smokable medical marijuana By Christine Sexton article TALLAHASSEE, Fla. - New rules laying out the do’s and don’ts physicians must follow when certifying patients to smoke medical marijuana took effect last week, but it’s not clear that doctors or patients are fully aware of them. Patients certified or recertified to smoke medical marijuana must sign a new standardized consent form as of last Tuesday. That form for the first time includes information about the dangers of smoking near oxygen tanks and advises patients to check their marijuana supplies for mold contaminants. Also, physicians must adhere to newly adopted practice standards that for the first time spell out what the doctors must do to certify patients and what information needs to be included in patients’ medical records.
