Marijuana’s legal status has recently undergone major changes. The federal Controlled Substances Act (CSA) still places marijuana in its most highly restricted category, but more than half of the states in the U.S., including Texas, now allow medical marijuana to some extent. Colorado, California, and several other states have legalized the production, sale, and possession of small amounts of marijuana for recreational purposes. This has led to legal disputes over whether states like Colorado have exceeded their constitutional authority. For criminal justice advocates in Texas, where marijuana remains a highly controlled substance, law enforcement attention to suspected interstate drug trafficking raises a variety of constitutional civil rights questions.
The CSA classifies “marihuana” as a Schedule I controlled substance. 21 U.S.C. § 812(c)(I)(c)(10). The statute prohibits “manufactur[ing], distribut[ing], or dispens[ing]” a controlled substance, or “possess[ing] with intent to” do any of the aforementioned acts with a controlled substance. Id. at § 841(a)(1). Penalties depend on the identity and amount of the controlled substance involved. Texas marijuana law classifies THC, the active component of marijuana, in Penalty Group 2. Tex. Health & Safety Code § 481.103(a)(1). It identifies numerous offenses related to the manufacture, delivery, and possession of both Penalty Group 2 controlled substances in general and marijuana in particular. See, e.g. id. at §§ 481.116, 481.121.
The U.S. Constitution’s Commerce Clause authorizes Congress “to regulate Commerce…among the several States.” U.S. Const. Art. I, § 8, cl. 3. The CSA has faced constitutional challenges alleging that the federal government lacks jurisdiction to enforce federal drug laws within states that have legalized marijuana to various extents. The Supreme Court rejected this argument in Gonzales v. Raich, 545 U.S. 1 (2005), but it remains a controversial question. The federal government’s authority to deal with controlled substances that cross state lines, on the other hand, rather unambiguously falls within the federal government’s constitutional authority. This is where many recent legal challenges have arisen.
