Heads up, this is going to be huge.

Today is National Brownie Day, and to celebrate, a Massachusetts cannabis company has created what they believe to be the “largest THC-infused brownie ever made.”

MariMed Inc. said the massive confection is 3-feet-by-3-feet (.9-meters-by-.9 meters) square and 15 inches (38 centimeters) tall, weighs 850 pounds (385 kilograms), and contains 20,000 mg of THC.

For context, the average cannabis edible contains about 10-15 mg of THC. So, safe to say this infused delight probably won’t be consumed in one sitting.

The brownie was also made to celebrate the launch of the company’s new line of cannabis-infused edibles, called Bubby’s Baked, according to a statement from the Norwood-based company that also has facilities in several other states.

What happens to the brownie now? Company spokesperson Howard Schacter said it will be sent to its Middleborough dispensary and ultimately sold to a medical marijuana patient. As to what the customer plans to do with it, Schacter couldn’t say.

The purchase price is still being determined, he said.
