A proposed Pennsylvania State Senate bill would allow medical marijuana patients to buy edibles. Currently, they may only buy their medicine in six forms: pills, oils, topicals, dry leaf, tinctures and liquids. The bill’s sponsor says the state’s lack of action on the idea has prompted many users to try to make their own edibles at home. But Senator Dan Laughlin says a lack of uniformity can cause them to accidentally consume too little or too much medicine when they make it into cookies, brownies, and other foods. He says 25 other states have legalized edibles for medical cannabis.
