Marijuana, psychedelics get a second look from Big Pharma

Details: CNBC reports that Walgreen's will sell cannabis-oil products, including creams, patches and sprays, in some 1,600 stores across 6 states. CVS embraced CBD drugs earlier this month.

For psychedelics, the FDA's approval of a "ketamine-like" drug to treat severe depression has already provided one popularity boost, CNBC's Christina Farr writes.

• On the heels of that decision, ATAI, a German company specializing in "formerly stigmatized compounds," raised $40 million, for a valuation of $240 million.
• "Biotech investors believe that psychedelic medicine will experience a revival in the wake of recent research studies as well as some early signals of support from regulators," Farr reports.

Between the lines: CBD and psychedelic medicine are very different. Cannabis oil doesn't produce a high like smoking marijuana does. Psychedelic drugs do still have profound effects on the brain, which is why they're so tightly regulated and scarcely used.

• If there's a constant here, though, it's a willingness to look at, as ATAI puts it, "formerly stigmatized medicines."
• The opioid epidemic has opened up new approaches to pain therapy; treatment-resistant depression demanded something; the criminal justice system is reevaluating drugs, too; and regulators are willing to give these products a shot.
