Wash. Admin. Code § 246-70-010
Anecdotal and limited scientific evidence indicates that the use of marijuana may be beneficial to alleviate the symptoms of certain physical and mental conditions. However, due to the current federal classification of marijuana as a schedule 1 controlled substance, scientific research has not been performed that would allow for standardized indications of particular strains, which can vary radically in cannabinoid composition; standard, reproducible formula or dosage; or accepted standards for drug purity, potency and quality for the various conditions for which the medical use of marijuana may be authorized. At this time, the decision of what marijuana products may be beneficial is best made by patients in consultation with their health care practitioners. For this reason, the department will not limit the types of products available to qualifying patients. Instead, the department intends to create standards for products that any consumer can rely upon to be reasonably safe and meet quality assurance measures.
