Amendment 484 demonstrates the Commission’s intention that not all materials that are combined or “mixed” with controlled substances should be included in the weight of the drug for sentencing purposes. The liquid solvent thus may not be included in the definition in Amendment 484 of “mixture or substance” given that, although wholesale traffickers use the solvent to apply the drug to ingestible carrier media, consumers do not “use” the solvent because it evaporates from the carrier media before the media are ingested.

C: holding that doctrine does not violate due process
D: holding that omission was not plain error
