Summary

Portrait of William Rehnquist William Rehnquist Chapman v. United States — Opinion of the Court

Petitioners argue that those selling different numbers of doses, and, therefore, with different degrees of culpability, will be subject to the same minimum sentence because of choosing different carriers. [6] The same objection could be made to a statute that imposed a fixed sentence for distributing any quantity of LSD, in any form, with any carrier. Such a sentencing scheme-not considering individual degrees of culpability-would clearly be constitutional. Congress has the power to define criminal punishments without giving the courts any sentencing discretion.

We think that petitioner's reading of the statute-a reading that makes the penalty turn on the net weight of the drug rather than the gross weight of the carrier and drug together-is not a plausible one. The statute refers to a "mixture or substance containing a detectable amount." So long as it contains a detectable amount, the entire mixture or substance is to be weighed when calculating the sentence.

Although LSD is not sold by weight, but by dose, and a carrier medium is not, strictly speaking, used to "dilute" the drug, that medium is used to facilitate the distribution of the drug. Blotter paper makes LSD easier to transport, store, conceal, and sell. It is a tool of the trade for those who traffic in the drug, and therefore it was rational for Congress to set penalties based on this chosen tool.
