Now that recreational marijuana has been legalized in our state, key questions are arising. 

This symposium, attended by 150 people from organizations involved in research, treatment, prevention, and policymaking explored:

· What we already know about marijuana use
· What we need to know
· How research can inform both policy and practice

The symposium, the first in a series, featured researchers from the University of Washington and speakers from the community, with interactive discussion and Q&A sessions.
