And how on earth are they so widely available???
They are explosives for God's sake!
for retail sale, the vendors have to apply to the local authority for a icence under the Expolsives Act 1875, and there are strict regulations relating to storage, signage, as well as all the age restricted issues.
inspectors are sent out every year to check for compliance. this area of enforcement was always given a very high priority by Trading Standards.
