“We have over 200,000 patients registered (with medical marijuana cards ) in Pennsylvania right now and every single one of us is DUI 24 hours a day, seven days a week, 365 days a year if we’re using medical cannabis under Pa. law,” said Nightingale, who’s working with the legislature in an effort to change the driving laws. He argues that police should have to prove impairment just like in cases involving alcohol. Bills are currently sitting in the House and Senate that would do just that, but Nightingale said there’s been no movement.
