Los Angeles Times: Mayors in two Massachusetts cities want to ban Lazy Cakes, brownies laced with the sleep-inducing hormone melatonin, because the psychedelic packaging with a cartoon brownie may be enticing to children, according to news reports. Lazy Cakes, sold at some convenience stores and online, are touted on their website as "a delicious, chocolate alternative to medication and harmful narcotics to help you safely relax and fall asleep."
