Abstract
A transdermal structure is provided for delivering cannabis chemical(s) to one's bloodstream. The structure comprises a backing layer which carries the cannabis chemical(s). The chemicals are contained in a film on the backing layer or within a cavity formed in the backing layer. Alternatively, an opening in a secondary layer that overlies the backing layer may be used to create the cavity. The structure is applied to one's skin so that the cannabis chemicals are in contact with the skin. A polymer material which is mixed with the cannabis and placed in the cavity or a membrane over the cavity may be used to control the flow of cannabis chemical(s) into the bloodstream. In an alternative embodiment, a porous material impregnated with cannabis chemical(s) may be used to hold the chemical(s) in the cavity.
