[Editor’s Note: On Jan. 21, 2010, the Supreme Court of the State of Washington ruled that Ballot Initiative “I-692 did not legalize marijuana, but rather provided an authorized user with an affirmative defense if the user shows compliance with the requirements for medical marijuana possession.” State v.

ProCon.org contacted the Washington Department of Health to ask whether it had received any instructions in light of this ruling. Kristi Weeks, Director of Policy and Legislation, stated the following in a Jan. 25, 2010 email response to ProCon.org:
“The Department of Health has a limited role related to medical marijuana in the state of Washington. Specifically, we were directed by the Legislature to determine the amount of a 60 day supply and conduct a study of issues related to access to medical marijuana. Both of these tasks have been completed. We have maintained the medical marijuana webpage for the convenience of the public.
The department has not received ‘any instructions’ in light of State v. Fry. That case does not change the law or affect the 60 day supply. Chapter 69.51A RCW, as confirmed in Fry, provides an affirmative defense to prosecution for possession of marijuana for qualifying patients and caregivers.”]
