Palcohol, the powdered alcohol product has been approved for sale in the United States. Palcohol came under a lot of criticism last year when it initially launched with a website promoting irresponsible uses of its product, a powder that you can mix with water to create an alcoholic drink. Even after cleaning up its website, Palcohol then ran into another snag: as it turned out, US regulators had unintentionally approved it for sale and were backtracking on that approval. It’s now almost a year later, and the Associated Press is reporting that Palcohol has received proper federal approval to put four varieties of its product up for sale. Palcohol says that it’s hoping to be in stores this summer.
