A Toronto business has been holding daily scavenger hunts in the city with unusual prizes: medical marijuana vouchers.

The Marijuana Information Bureau (MIB) holds the events every weekday between 5 p.m. and 9 p.m. and posts the locations on Twitter with the hashtag #hiddenWEED.

Anyone 19 years of age and older and who holds a medical marijuana license can redeem the vouchers for weed.

A massive scavenger hunt is planned in High Park on Sept. 7.
