B. Although the medical marijuana market is less regulated, the similarity in taxes between the two markets should make prices competitive.
Explanation:
In a state like Washington where marijuana is regulated and legalized for both medical and recreational use, taxes for these two uses must be similar. This serves not only to make prices competitive, but also to prevent people from buying medical marijuana (which is less regulated) for recreational use, and vice versa. In short, this equalization of taxes is done to control not only production, but purchase and use as well.
