In July, the UK government announced plans to establish a new unit to help tackle drug misuse and related deaths, which are at a record high, having increased by almost 80 percent since 2012.

UK Prime Minister Boris Johnson is due to unveil a 10-year plan on Monday to grapple with illegal drug-related crime, which may include measures to revoke offenders' documents.

During tomorrow's announcement of a crackdown on addicts, casual drug users, and dealers, Johnson is expected to promise the allocation of at least £700 million ($926 million) over the next three years for the purpose, according to the British media.
