The response was thus:
Here is some information that my staff found:

Are sales of "Medical Marijuana" subject to sales tax?

In the state of Washington, sales of medical marijuana are retail sales. As such, the selling price is subject to retail sales tax. In addition, the seller is subject to the business and occupation (B&O) tax under the retailing classification. This is true even if it is sold by a medical marijuana dispensary.

Sales of medical marijuana are not eligible for the retail sales tax exemption provided for prescription drugs. RCW 82.08.0281 provides an exemption from retail sales tax for certain drugs, but only when prescribed as authorized by the laws of this state. However, marijuana is a Schedule I controlled substance and cannot be prescribed under either federal or state law in Washington.

Chapter 69.51A RCW addresses medical marijuana, but does not authorize the prescription of medical marijuana. This chapter specifically avoids authorization of a prescription by referring to ā??valid documentationā?, which does not equate with a prescription as defined in RCW 82.08.0281(4)(a), or as provided in RCW 69.50.308 (Prescriptions). Chapter 69.51A provides that it is only intended to protect qualifying patients, designated providers, and physicians from liability, prosecution, or criminal guilt when marijuana is possessed, used, provided or authorized.



With regards to dispensaries, I have been told that they are legal for the purpose of dispensing medical marijuana which then would make then eligible to be taxed.



Does that help answer your questions/address your concerns?
I have asked for further information regarding that dispensaries are in fact legal, which I have been adamant about saying they are not.......If that is the case maybe some of us folks in Clark, Skamania, and other close to Vancouver counties should get together and start a non-profit co-op in Clark County. As far as I know, there is not one here.
WashougalWonder Reviewed by WashougalWonder on . AP exclusive Now this is a good one. Far out...but wait, doesn't the State also state that dispensaries are illegal? Now I do not know where the exact clause is, but on the DOH website in FAQ the following: From: Medical Marijuana Frequently Asked Questions - Washington State Dept of Health fricking oxymoronic crap.
