Mother has created radio and outdoor ads for the Home Office's "Talk to Frank" campaign.
The work aims to encourage young people to seek accurate and impartial information about drugs.
It targets 11- to 18-year-olds and will run across radio, print and online, posing drug-related questions such as "How long is a line of cocaine?" and "Does meow meow have whiskers?"
The radio ads feature young people asking for advice from unlikely characters to communicate the idea that only Frank knows the right answers to questions about drugs.
The digital work, which re-uses executions from previous campaigns, features three ten-second films showing the effects of drugs in unusual scenarios to comedic effect.
