Attention Pisces of the D.C. area: Astro Doughnuts & Fried Chicken is adding an extremely chill element to its birthday cake doughnut just in time for your big day. Starting today, two of the chain’s locations will add CBD oil to Astro’s signature cake doughnut.

Astro—which previously brought us doughnuts adorned with mustaches, dusted with Old Bay, and stuffed with gravy-slathered fried chicken—normally fills its birthday cake doughnut with a vanilla buttercream and tops it with vanilla glaze and sprinkles. For the next two weeks, the special version of the chocolate cake doughnut comes with a CBD-infused chocolate buttercream. The vanilla option—sans-CBD—will still be available.

CBD, aka cannabidiol, is a component of the marijuana plant that lacks THC (tetrahydrocannabinol), which is the part that contains psychoactive properties. Now found in products as diverse as bath bombs, gummy candy, and lotions, CBD is used to treat anxiety, pain, and other ailments. The medical jury, as it were, is still out on how effective CBD truly is as a treatment.

At $4.50, Astro’s CBD doughnut will be available for walk-in orders only (so no getting a dozen CBD doughnuts catered to your office meeting) at just two locations: G Street NW in D.C. and Falls Church. The doughnut is on offer through March 14, but a representative says it could be extended if the snack proves popular.

Of course, this is far from the first way to incorporate CBD into your breakfast: A handful of cafes in the area offer coffee infused with CBD. Gregorys Coffee allows you to add CBD oil to any drink on the menu.
