Orrick, Herrington & Sutcliffe announced a pro bono partnership Thursday with the Americans for Safe Access Foundation, a medical marijuana advocacy group, signifying to some that the push to make legal cannabis available to patients nationwide has gone mainstream.

The Oakland, California-based nonprofit, which lobbies lawmakers on how to improve their states’ medical marijuana laws and seeks to educate patients on their rights, will work with Orrick lawyers to update a series of manuals on state medical marijuana laws. Eventually, Orrick hopes to coordinate a hotline for medical marijuana patients in need of legal advice that will involve other law firms.
