Saturday is a high-ranking made-up holiday.

It's 4/20, aka Weed Day or Pot Day, and that means specials for cannabis fans across the country, regardless of whether they can legally buy pot in their state or not.

This year, more major restaurant chains are getting in the holiday mood including Pizza Hut, which has a sweet brownie deal, and Boston Market with its buy-one-get-one free Pot Pie deal.

Plus, Carl’s Jr. says it is the first chain to test a CBD-burger at one Denver location only on Saturday.

CBD, a hemp-derived cannabidiol, is a nonpsychoactive ingredient in cannabis that is becoming increasingly mainstream.

Cannabis-based products got a major boost in December when President Donald Trump signed off on an $867 billion Farm Bill that gave a green light for hemp to be cultivated on a large scale.

Walgreens, CVS and Rite Aid have announced that they are introducing CBD topical products in some locations.

Unlike marijuana, another cannabis species, hemp has almost none of the psychoactive compounds that cause a user to get high. Now that it's no longer labeled a controlled substance, more businesses have the opportunity to create hemp-based products, from tinctures to lotions.

Here are some of munchie deals, not drug deals, though you might find a discounted buzz Saturday:
