The Dutch and Brits have recently taken legislative action to implement laws that restrict public access to precursor chemicals.
Private persons are no longer allowed to purchase chemical substances that can be used to make explosives, when they do not have a licence to do so. Neither are they allowed to import, possess or use these substances, when they do not possess the required documents. In addition, sellers and private persons will soon be required to report suspect transactions, disappearances, and thefts of such chemicals to the authorities.
The British Parliament will soon take up The Control of Poisons and Explosives Precursors Regulations 2015 act.
