This looks like the important part.
"23 (5) The affirmative defense established in subsection (2) of this
24 section shall not be available to a qualifying patient if:
25 (a) Marijuana is listed as a Schedule I controlled substance under
26 state or federal law; or
27 (b) The marijuana in question was not produced in compliance with
28 all applicable state and federal product safety laws."

So it just contradicts itself. Typical. Hopefully Sensible Washington's intiative will be passed and all this will be mute for atleast 2 years anyway.
