There's a sea change coming for the $1 billion marijuana-based industry you've never heard of - here are some of the most popular products

In states where cannabis has been legalized, marijuana-derived CBD products include everything from gummies and vape pens to flower with a high CBD-to-THC ratio.

Because recent evidence has suggested that CBD is a key compound in marijuana linked with many of its therapeutic benefits, there's a sudden surge in interest to make products with a higher ratio of CBD compared to THC, its main psychoactive component.

That's a sharp departure from a trend that's been ongoing for the past few decades, where growers have been increasingly cultivating weed that's higher in THC and lower in CBD.

Water, teas, and even kombucha strains made with CBD are popping up in grocery stores around the country.

Berkeley, California-based retailer Berkeley Bowl recently began selling a juice drink called Vybes which contains 15 milligrams of hemp-derived CBD as well as a type of kombucha called Cannabliss by GT that is made with CBD. Both drinks are advertised as having calming and soothing qualities, but any alleged health benefits have not yet been borne out by scientific research.

Regardless, another company in Denver called Phoenix Tears recently signed an agreement with MarketHub Retail Services, a distributor that works with 7-Eleven franchisees, to get its hemp-derived CBD products in up to 4,500 stores by the end of this year.

"This agreement confirms our belief that CBD's status as a mainstream wellness option has arrived," Phoenix Tears founder Janet Rosendahl-Sweeney said in a recent statement.

Brewing companies are capitalizing on the nascent CBD boom, too. California-based Lagunitas is debuting two non-alcoholic cannabis drinks on July 30; one with 5 mg CBD and THC and another with 10 mg of THC only.

The canned drinks are called Hi-Fi Hops and will be made in collaboration with vape cartridge company CannaCraft. They'll sell for $8 each throughout California and be calorie-free.

It turns out that dozens of pet treat manufacturers make hemp-derived CBD treats for four-legged friends that can be purchased in stores and online.

These treats contain zero THC, the psychoactive component of cannabis that animals can be highly sensitive to (and even die from), so be sure to verify that the treat you're giving your pet is CBD-only.

Colorado-based coffee company Strava Craft Coffee began selling coffee made with CBD oil last year.

"These specialty-grade coffees are craft roasted in Denver, Colorado, and precision infused with CBD-Rich Hemp Oil to bring balance and natural plant wellness to every cup; including powerful antioxidants and neuroprotectants," Strava wrote in a press release.

But for now, purchasing products made with CBD is somewhat of a gamble. Based on the current research, it's premature to claim that the ingredient would have any measurable health benefits for most people. That said, it's clearly a lucrative — and blossoming — industry.
