When it comes to synthetic drugs like MDMA the Dutch organized crime networks (in particular those of North Brabant ) are arguably the biggest players in the world together with Israeli organized crime.

People are always talking about the cocaine trafficking gangs that are based in the Netherlands because the cocaine business generates the most violence, but a lot seem to forget that the xtc and amphetamine production in the Netherlands has a yearly turnover of close to 19 billion. On a global scale I'd wager that the Dutch networks involved in synthetic drugs are bigger than the ones involved in cocaine.
