SALEM, Ore. (AP) – Senate lawmakers have given the greenlight to a bill that would allow recreational marijuana dispensaries to sell medical marijuana to patients tax-free. Senate Bill 1511 cleared the Senate on an 18-10 vote Tuesday and now heads to the House. The bill integrates Oregon’s recreational and medical marijuana systems, which are currently overseen separately by different state agencies. Under the legislation, when Oregon’s recreational dispensary program launches next year, consumers will still be able to buy recreational and medical pot under one roof as they do now under an early sales program that began in October at medical dispensaries only. The bill also would allow recreational consumers 21 and over to buy marijuana-infused edibles and concentrates, something currently available to only medical patients.
