Marijuana opponents, frustrated by the growing number of legalization victories across the U.S., are increasingly trying to rein in the industry by proposing state-level caps on THC potency.
The push involves at least six bills introduced in four state legislatures: Florida, Massachusetts, Montana and Washington.
A bill was derailed in Colorado before it could be introduced because it triggered a backlash.
Industry insiders suggest such moves could mean a return to prohibition, since many of the proposals would cap THC beneath what’s currently available in many state-legal markets.
Banning those products, industry proponents warn, would create a new illicit market for higher-potency cannabis and spawn more underground competition for legal marijuana companies.
That, in turn, could restart the war on drugs.
