The Ontario Cannabis Festival takes place on September 7th and along with all the festivities, they're looking to "smoke" a world record by rolling a 110 foot joint.
While no official record exists, the longest they could find was 106 feet. The organizers are seeking volunteers to contribute (don't worry, you will get your cannabis back) as much as they can because legally, each attendee can only carry 30g. Every 3.5g will add 1 foot to the world record attempt so consider this a "pot luck" of sorts.
Besides this world record attempt, there will also be tons of workshops, vendors, and performances from DJ Flash, The Liberation Band, Hugo Alley, and many more. You can get all the info or purchase your tickets from their website.
