De wereld gebruikt veel minder XTC pillen dan geschat

Op 25 augustus 2018 kwam het boek “Waar een klein land groot in kan zijn” uit van Pieter Tops, Judith van Valkenhoef, Edward van der Torre en Luuk van Spijk. In dit boek berekenden de auteurs dat er jaarlijks in Nederland 971 566 879 XTC pillen worden geproduceerd, waarvan 80% wordt geëxporteerd. Er zijn veel reacties op dit boek gekomen, waar de auteurs op hebben gereageerd door met een ander exportpercentage de totale omzet te herberekenen. In deze blog post reageer ik hierop door uit te rekenen hoeveel XTC pillen de wereld elk jaar consumeert, waaruit volgt dat niet het exportpercentage niet klopt, maar de geschatte totale XTC productie.

This book prompted many reactions, and the authors responded to these again by recalculating the export percentage. In this blog post I respond by calculating how much XTC the world uses every year, a number that implies that the export percentage was not what was incorrect, but the total production estimate.

Much less ecstasy used (and produced?) in the Netherlands than recent report suggests

Recently, a report came out (“Waar een klein land groot in kan zijn”) by Pieter Tops, Judith van Valkenhoef, Edward van der Torre and Luuk van Spijk (all employed by the Dutch Police Academy) drawing two sensational conclusions. First, that every year, the Netherlands produces € 18 916 882 439 (18,9 billion) worth of synthetic drugs. Second, that in the Netherlands, every year 194 313 376 ecstasy pills are used. This latter conclusions is clearly wrong, which sheds doubt on the veracity of the former. Both the original report and the abbreviated version are written in a sensationalist tone; might the authors have neglected to verify their impressive conclusions with sufficient rigor?
