MariMed celebrated the launch of its new Bubby's Baked brand by cooking a treat infused with 20,000 milligrams of THC - the main psychoactive ingredient in marijuana.

The brownie measures three feet long on each side and is 15 inches high. It dwarfs the previous record holder - a 234-pound brownie made in Alabama in 2013.

However, MariMed have been left disappointed as the brownie will not be considered for the record under Guinness rules.

The firm's chief product officer Ryan Crandall said: "Unfortunately, Guinness World Records rejected our entry because they don't accept cannabis-related records.

"That was a disappointment, but we're still very proud of what we accomplished."

The treat - which was unveiled to mark National Brownie Day on Wednesday (08.12.21) - will now be sold to a MariMed medical marijuana patient.
