Components in extracts of marihuana and hashish have been identified by a chromatographic technique in which centrifugal force is used to accelerate the migration of samples through columns of densely packed microparticulate gel. Rapid qualitative analysis and an estimate of the amounts of cannabinoids present was achieved.
