State v. Wadsworth
In State v. Wadsworth, 109 Ariz. 59, 60, 505 P.2d 230, 231 (1973), the defendant asserted that classifying marijuana with narcotic drugs violated the equal protection clauses of the Arizona and United States Constitution. He presented evidence to demonstrate that the legislature's classification of marijuana with narcotic drugs rather than with dangerous drugs was arbitrary. Id. at 62, 505 P.2d at 233.
In rejecting the evidence, the Arizona Supreme Court held that "[t]he legislative intent in this State was to proscribe the use of marijuana, not to scientifically categorize it according to its composition and effect." Id. at 63, 505 P.2d at 234.
Wadsworth also took judicial notice of the fact that "marijuana is one of the most widely used drugs among our young" and concluded that controlling a widespread, objectionable practice with harsher penalties was reasonable. 109 Ariz. at 63, 505 P.2d at 234.
