The sole point on appeal asserts the unconstitutionality of section 893.13(l)(e), Florida Statutes (1987), which proscribes the sale of a controlled substance within 1,000 feet of school property. Following State v. Burch, 545 So.2d 279 (Fla. 4th DCA 1989), review granted (Fla. Case no. 73,826; argued, Sept. 7, 1989), and our previous decision in Austin v. State, 549 So.2d 1153 (Fla. 3d DCA 1989), we reject *406this contention and affirm the judgment below.
