In Fountain v. Oelschlegel, 9 Ariz. App. 236, 239, 451 P.2d 316, 319 (1969), the Court held that a licensing statute for pharmacists permitting revocation for "gross immorality" was not impermissibly vague. The statute listed three other bases for revocation and authorized a hearing to determine whether the licensee in that case had sold drugs without a prescription. Id. at 237-38, 451 P.2d at 317-18. It was "sufficiently clear to apprise any pharmacist of the course of conduct he must follow if he wishes to keep his license." Id. at 239, 451 P.2d at 319.
