The new rule isn't any better than the old rule.
C/P
The department has adopted the rule defining a 60-day supply of marijuana for medical use under the state’s medical marijuana law. The rule becomes effective on November 2, 2008.

The rule includes changes made after careful consideration of comments received from the public. The new rule removes the definition of mature and immature plants and simply sets the total number of plants at 15. The 24-ounce total for useable marijuana has not changed. The rule also removes the requirement for a doctor to provide written documentation for a patient to exceed the limit in the rule.

Look at the last sentence. So basically it says ignore the limits set in the new rule if you feel like you need more than that.
killerweed420 Reviewed by killerweed420 on . New to washington state getting worried Hi Im new to washington state. (only here 7 months). Moved from California and was medical for 6 years. Ive read some of the forums on washington laws and am starting to get a little paranoid. I grow my own, very stealth-like. But see that even one plant is a felony. Coming from the bay area that seems ludacris to me. So with prop 215 you just went to a doctor paid a small fee $250-300 the doctor gave a consult, had you bring in any documentation (perscriptions,etc) And you got your Rating: 5
