Supporters of the current medical marijuana system in Washington state crowded a public hearing on Wednesday to decry proposed changes.

The Health Care & Wellness Committee held its first hearing on a measure seeking to overhaul the state's medical marijuana system in order to reconcile it with the new legal recreational market.

The changes under the bill sponsored by Democratic Rep. Eileen Cody include reducing the amount of marijuana and number of plants patients can possess, doing away with collective gardens and establishing a patient registry.
