The Dutch government is to press ahead with experiments in regulated marijuana production involving 10 licenced growers, according to the detailed plans which were published on Thursday. The long-awaited experiment with regulated growing is supposed to remove the gray area between the sale of marijuana in council-licenced coffee shops and the illegal cultivation and supply. The plans, which were put out to consultation last year, state that the 10 growers will all have to produce at least 10 different types of marijuana product and the thc content will have to be clearly marked on the packaging. In addition, ministers have confirmed a minimum of six and maximum of 10 local authority areas will take part in the trials, which will run for at least four years. This means it will be up to the next cabinet to decide if the Netherlands should press ahead with state-controlled marijuana.
