The Chad Green case has again focused national and international attention on the unproven cancer remedy known as laetrile. Laetrile has attracted considerable attention in recent years as a result of claims that it is a nontoxic form of cancer treatment. Twenty-one states have legalized prescription of laetrile within their borders, despite the efforts of the Food and Drug Administration (FDA) to keep laetrile off the market.
The authors examine the claims about laetrile’s effectiveness and comment upon scientific tests concerning its efficacy. They maintain that scientific support for the use of laetrile is almost totally absent and that evidence of the dangers of laetrile is substantial. After reviewing the medical evidence concerning laetrile, the authors describe the efforts of laetrile proponents to use the courts as the battleground to legalize laetrile. In early skirmishes, laetrile proponents were successful in opposing the efforts of the FDA; under a constitutional privacy theory several courts upheld the right of competent adults to select laetrile therapy.
Subsequently, however, as the authors demonstrate, the U.S. Supreme Court, in United States v. Rutherford, and the California Supreme Court, in People v. Privitera, narrowed the federal constitutional privacy right by declining to read into it a right to take laetrile. Finally, the Massachusetts Supreme Judicial Court, in the Chad Green case, considered the question of laetrile’s toxicity to a recipient of the drug.
The authors discuss the interrelationship among the three cases. They argue that the overwhelming proof in Chad Green that laetrile is harmful undermines any statutory or constitutional claims supporting legalization, because such claims assume that even if laetrile is not truly therapeutic outside of the placebo effect, it is not toxic. In light of the three decisions, the authors conclude that supporters of laetrile should not expect that the courts will be sympathetic to future legal efforts to approve or to permit use of laetrile therapy.
