Melatonin-laced brownies are raising eyebrows.
If you're looking for an instant jolt of energy there are countless ways to boost your caffeine level these days, but as Isaac Newton famously observed, what goes up, must also come down.
Enter the Lazy Cake, a so-called "relaxation" brownie sold in at least two dozen states.
Its purple packaging may conjure hazy impressions of a more illicit brownie, but there's no marijuana here.
The Lazy Cake contains melatonin, a common sleep aid sold over the counter.
"It helps us calm down and lower our core temperature and prepares us for sleep," explains Dr. David Zich.
Too much melatonin can have a powerful effect, sending the user into a deep sleep.
Supplements have been known to prompt thousands of calls to poison control centers, with many cases involving kids.
Arkansas has banned lazy cakes and one town in Massachusetts is working to do the same.
Its mayor says even though the package clearly says lazy cakes are for adult use only "its psychedelic packaging and cartoon character known as Lazy Larry indicates otherwise".
The makers of Lazy Cakes say they encourage store owners to place them in areas with other dietary supplements intended for adults.
One Lazy Cake contains double the usual recommended dose for an adult.
The serving size is half a brownie.
Lazy Cakes aren't the only melatonin brownies on the market.
Kush Cakes and Lulla Pies are also sold nationwide.
