“Relaxation” snack foods and soft drinks are safe and effective.
Their safety depends on whether you read and follow labels.
Most “relaxation” products contain melatonin and valerian root, and sometimes passionflower, kava, and other ingredients traditionally used for stress or sleep. None of these agents has been proven to be safe and effective, although melatonin and valerian are possibly effective for insomnia.
“Relaxation” products go by names such as Lazy Cakes, Kush Cakes, Unwind, Slowtivate, etc. They come as brownies, cookies, and soft drinks that are sold online and at smoke shops, convenience and liquor stores, etc.
