The US state of Washington says licensed marijuana stores can offer free joints to promote coronavirus vaccine clinics.
The "Joints for Jabs" programme announced by state officials this week will permit pot retail shops to give away a single pre-rolled joint to anyone over 21 who gets a shot at an on-site vaccine clinic by July 12.
The state already lets breweries, wineries and restaurants offer free drinks in exchange for proof of vaccination. Other incentives include free sports tickets and prize money of up to $1 million.
The idea is to persuade more people to become vaccinated. Governor Jay Inslee intends to lift all pandemic restrictions at the end of the month or sooner if 70 per cent of those aged over 16 have received at least a first vaccine dose.
