Look at the definition of "medical use" in Amendment 20:

(b) "Medical use" means the acquisition, possession, production, use, or transportation of marijuana or paraphernalia related to the administration of such marijuana to address the symptoms or effects of a patient's debilitating medical condition, which may be authorized only after a diagnosis of the patient's debilitating medical condition by a physician or physicians, as provided by this section.

HB10-1284 did not redefine this and it actually refers to "medical use" in this bill.

Unless, of couse, I missed it somewhere.
