title: Heroin in the Netherlands.
abstract: All heroin samples seized in the Netherlands in 1975 and weighing more than 10 grams together with all heroin samples seized during September 1976 were analysed by thin-layer chromatography, gas-liquid chromatography and liquid-solid chromatography. Most samples consisted of the so-called Hong Kong No. 3 type. Also the samples found in addicts were as potent as those seized from dealers and traffickers. We attempted to classify the samples into groups or batches, but only in a few cases could we conclude that two or more samples originated from the same batch.
