While drug laws at the federal and state levels classify a vast array of “controlled substances,” two in particular have stood out in recent political and legal debates. The legalization of marijuana for medical use is now a reality in at least 26 states, including Texas. Several states have gone a step further and legalized the distribution and possession of small amounts of marijuana for recreational use. At the same time, opioid use is on the rise across the country, and the number of deaths resulting from overdoses have led many to call it an “epidemic.” Both drugs are scheduled as controlled substances, but the similarities mostly end there. Some research suggests that allowing medical marijuana use may reduce the number of opioid overdose deaths. Federal officials, however, continue to view opioid use as a matter of criminal enforcement rather than public health. The federal government’s approach to these issues is likely to influence the Texas criminal justice system’s response.
The term “opioid” can refer to almost any drug derived from opium, including heroin. In its current usage, it usually refers to prescription painkillers like hydrocodone and oxycodone, as well as synthetic products like fentanyl. Heroin is classified as a Schedule I controlled substance, meaning it has “a high potential for abuse” and “no currently accepted medical use.” 21 U.S.C. §§ 812(b)(1), (c)(I)(b)(10), (c)(I)(c)(10). Fentanyl and many other pharmaceutical opioid products are Schedule II controlled substances, meaning that, while addictive, they have medical uses. Id. at §§ 812(b)(2), (c)(II)(b)(6). The Drug Enforcement Administration moved hydrocodone from Schedule III to Schedule II in 2014, largely because of the increase in overdose deaths. 79 Fed. Reg. 49661 (Aug. 22, 2014).
Scientific studies have not shown marijuana to have addictive properties at all similar to those of opioids. It is nevertheless classified in Schedule I alongside heroin. 21 U.S.C. §§ 812(c)(I)(c)(10). Numerous state medical marijuana laws dispute the assessment that the drug has no accepted medical use. The Texas medical marijuana law is among the most restrictive in the country, and it allows the use of “low-THC cannabis” only in the treatment of intractable epilepsy. See Tex.
