HARRISBURG – The state Senate Law and Justice Committee heard a wide range of testimony at a hearing on a bill to allow marijuana for medical purposes. Senate Bill 1182 is sponsored by Lebanon County Sen. Mike Folmer, who said the testimony was helpful in addressing misconceptions about the use of medicinal marijuana. Parents of children who suffer from seizures made appeals to the committee to allow doctors to prescribe marijuana extracts. They said government-approved drugs not only failed to stop the seizures but cause severe and sometimes violent side effects. Josh Stanley, who co-founded a Colorado nonprofit that’s exploring medical marijuana use, told the panel that compounds in the plant could treat diseases including cancer, epilepsy, multiple sclerosis, and diabetes. The Pennsylvania Medical Society withheld its support of the bill, saying more study is needed. Gov. Tom Corbett opposes the measure.
