More than 90% of the Dutch cannabis that is sold in coffee shops contains traces of illegal crop protection products. This is the outcome of a research conducted by the Dutch National Institute for Public Health and Environment.
The Dutch Public Health Institute RIVM investigated 25 samples of cannabis from coffee shops throughout the country. On 23 of them they found traces of one or more kinds of pesticides. Some of the cannabis contained traces of up to four kinds of pesticides. In most cases the pesticides were illegal products, that have been banned or strictly regulated for the use in the production of lettuce, tomatoes and fruits.
Fifteen years ago almost the half of the Dutch cannabis contained traces of pesticides. The sharp increase to 92% can be a result of the increase in illegal cultivation. This caused a decline in the amount of smaller, organic cannabis growers who could no longer compete in the market.
