Illinois officials have posted emergency rules spelling out how the state’s medical marijuana program will be extended to children under a law taking effect January 1, 2015.  The Department of Public Health posted the regulations online Tuesday.  Children with certain health conditions, including seizures from epilepsy, will be able to use non-smokable forms of marijuana.  But they will need two doctors to sign forms certifying they think the patient will benefit.  The rules expand a medical marijuana advisory board to include a parent or caregiver of a patient under age 18 and a medical professional with experience in pediatrics.  The emergency rules are in effect for 150 days.  A draft of permanent rules will be published later, which will trigger a 45-day public comment period.
