The state Senate Health and Long-Term Care Committee approved a bill aimed at clarifying Washington’s law on the medical use of cannabis. The bipartisan measure was introduced by Sen. Jeanne Kohl-Welles, D-Seattle, and co-sponsored by Sen. Jerome Delvin, R-Richland. Senate Bill 5073 would allow patients to purchase medical marijuana products from licensed dispensaries by taking part in a regulated patient collective, or by continuing to receive it from a designated provider. The Department of Agriculture would create a licensing system for the growing of medical marijuana and the Department of Health would do the same for dispensaries.
