We affirm appellant’s conviction for purchase of cannabis * on the authority of Blankenship v. State, 545 So.2d 908 (Fla.2d DCA 1989). As in Blankenship we certify to the Florida Supreme Court the following question, which we deem to be of great public importance:
DOES SECTION 893.13, FLORIDA STATUTES (1987), VIOLATE THE ONE SUBJECT RULE OF THE FLORIDA CONSTITUTION?
CAMPBELL, C.J., and RYDER and DANAHY, JJ., concur.
