This summer, before Seattle had seen its first legal marijuana shop, we here at the Weekly teased a pot product under development that we thought Seattleites in particular would be excited about—weed-infused coffee.

While that particular item hasn’t hit shelves yet, the Longview, WA company behind the product, Mirth Provisions, was able to get state approval for its weed-infused sodas, which just recently went on sale in Bellingham and Vancouver at the end of September.

In Bellingham, Top Shelf Cannabis sold 10 bottles the first day it stocked the soda, closed up shop, and returned the next morning to find that many of the bottles had self-destructed on the shelves, sending shards of glass and soda flying all over the store. The Vancouver store reported similar instances. Later, employees actually saw it happen themselves, according to KOMO:

“It sounded like a shotgun going off,” said Top Shelf Cannabis manager Zach Henifin. “You can actually feel it, it was that explosive”.Wearing a face shield and protective garb, Henifin placed cartons of unexploded soda in a steel box the size of a small dumpster outside of the store. The staff used bleach to clean up the mess and pulled pieces of glass from cardboard boxes. The “pot pop” continued to explode inside the steel container for 10 days.”It’s almost like bomb box because they randomly go off during the day,” said Henifin.

Apparently, the explosions were due to a soda batch with an excessively high yeast count that continued to drive the carbonation pressure levels up beyond the point of bottling, causing the glass bottles to erupt. Mirth is refunding the cost of the shipment to the stores and to the customers who purchased soda from the faulty batch.

Gives a whole new meaning to high-pressure, yuk-yuk-yuk.
