Forget THC! Cannabidiol (CBD) Is the Marijuana Industry's Moneymaker

Ready or not, legal marijuana is taking North America by storm. Even though the U.S. federal government has held firm on marijuana as a Schedule I drug (i.e., entirely illegal, prone to abuse, and not recognized as having any medical benefits), we've nevertheless witnessed 32 states legalize medical weed in some capacity. To our south, Mexico legalized medical pot in the summer of 2017 and is now strongly considering legalizing adult-use weed. And to our north, on Oct. 17, Canada became the first industrialized country in the world to give the green light to recreational cannabis.

According to investment firm Cowen Group, which has been one of the most optimistic Wall Street firms on the outlook for global cannabis, the industry could hit $75 billion in annual sales by 2030. This pie-in-the-sky sales figure is a big reason behind the lofty valuations of most marijuana stocks.

But what investors may not realize is that not all cannabis is created equally. Just as no two marijuana stocks are the same, neither are the prospects for different cannabis products. Whereas the world is eyeing sales of dried cannabis flower that's rich with tetrahydrocannabinol (THC), the cannabinoid responsible for getting a user "high," I believe it's the other important cannabinoid known as cannabidiol (CBD) that'll ultimately be the big moneymaker for pot stocks.

CBD is where the big money is

Cannabidiol, like THC, comes from the cannabis plant (although CBD can also be found in abundance via hemp). However, CBD doesn't get a user high. Rather, it's best known for its perceived medical benefits.

For example, GW Pharmaceuticals (NASDAQ: GWPH) earlier this year became the first drug developer to have the U.S. Food and Drug Administration approve a cannabis-derived therapy. Epidiolex, as it's known, is an oral CBD-based medicine that's designed to treat two rare forms of childhood-onset epilepsy. In clinical trials, GW Pharmaceuticals' lead drug wound up significantly reducing seizure frequency from baseline relative to a placebo. Eventual sales of GW Pharmaceuticals' top drug may top $500 million annually, but that will, of course, depend on insurer coverage and the willingness of physicians to prescribe Epidiolex.

The thing is, CBD isn't just limited to cannabinoid-based drugmakers. Marijuana growers can incorporate CBD into oils, capsules, pills, vapes, infused beverages, edibles, and pretty much any alternative form of consumption you can think of. It's worth noting, though, that with the exception of oils, alternative forms of consumption are currently illegal in Canada. However, Parliament is widely expected to discuss and approve new consumption options by next summer.
