The companies now must submit applications to the state for approval. But at this point, Nightingale added, companies have more questions than answers about entry to Pennsylvania. Theres no question about the medical benefits of a Green Rush non-addictive pain medication, which cannabidiol can provide, a physician and a cancer victim said Friday. Pennsylvanias law permits its use for treating 17 different medical conditions, including HIV/AIDS, cancer, autism, glaucoma, Parkinsons disease, Huntingtons disease, Crohns, sickle cell anemia, multiple sclerosis, severe seizure disorders and chronic neuropathic pain. According to information provided by Project CBD, a national organization that updates doctors, patients and the public on developments in cannabis science, cannabis can improve upon the pain relief that opioids provide; can prevent opioid tolerance building and the need for dose escalation; and decrease the symptoms of opioid withdrawal. Nightingale noted, however, that there is no medical insurance coverage for medical cannabis. Patients pay for it out of pocket, he said, adding that someone who has been paying $20 to $30 per month for an opioid pain medication at a pharmacy could go to paying hundreds of dollars per month for medical cannabis. Fridays panel included Sarah Bargas, a registered nurse and cancer survivor; Tom Perko, co-founder of the PMCS; and Washington physician Dr. Anthony Canterna. Bargas, who said she was diagnosed with stage 4 cancer in 2013, said she moved to Oregon, where medical cannabis is legal, and began taking cannabis oil as an alternative to opioids she was taking for pain relief.
