Glenn Wooden was convicted after a jury trial for possessing and distributing methamphetamine. Law enforcement had observed Wooden selling nearly 100 grams to informants and discovered another 222 grams in his apartment. During the trial, Wooden, who represented himself, argued that the government failed to prove he sold 'illegal' methamphetamine because they did not establish the specific molecular composition of the drugs. He contended that the Controlled Substances Act only criminalizes specific optical isomers of the drug, not the generic substance. The district court rejected this theory, instructing the jury that all methamphetamine is illegal, and sentenced Wooden to twenty-five years in prison based on the large quantity of crystal meth involved.
Chief Judge Brennan, writing for the panel, analyzed the statutory text and ordinary meaning of 'methamphetamine' at the time Congress enacted the Controlled Substances Act in 1970. The court explained that while the statute defines 'isomer' as 'the optical isomer,' it does not define 'methamphetamine' itself. Instead, the Act covers 'any substance… which contains any quantity of methamphetamine, including its salts, isomers, and salts of isomers.' The court reasoned that Wooden's interpretation would effectively read the word 'methamphetamine' out of the statute, violating the canon that every clause and word of a statute should be given effect. The court looked to dictionaries and regulatory history from the era of enactment, noting that the public and regulators understood 'methamphetamine' as a generic term covering various forms, including d-methamphetamine, l-methamphetamine, and dl-methamphetamine. The court clarified that its prior 'categorical approach' cases, which distinguished between federal and state definitions of isomers for sentencing enhancements, did not alter the statutory definition of the drug itself for conviction purposes. Consequently, the court held that the government only needed to prove the substance contained methamphetamine in any form, not a specific isomer. The court also addressed the testimony of the DEA chemist, ruling that he testified as an expert witness and that no procedural safeguards for 'dual-role' witnesses were required.
The decision affirms that federal drug prosecutions do not require the government to prove the specific isomeric composition of methamphetamine to secure a conviction or trigger mandatory minimum sentences. This preserves standard DEA testing procedures and jury instructions that treat methamphetamine as a generic controlled substance. The judgment against Wooden stands, and his twenty-five-year prison term remains intact.
