A bipartisan group of 22 Washington state legislators introduced a bill to curb the potency of marijuana concentrates.

Citing concerns about the connection between cannabis and psychosis, the lawmakers want to slash the potency of cannabis products, limiting THC levels to no more than 10%.    The ban would be limited, because it  doesn’t cover products sold as “medical.”

House Bill 2546, would outlaw the vast majority of state-licensed vape cartridges, dabs, wax, extracts and other concentrates. These products account for nearly 40% of state-regulated marijuana sales in 2019. 

In Washington, as in Colorado, typical strains of raw cannabis flower average around 20% THC. However, this bill only applies to extracts, and it would still allow the high-potency raw marijuana.

Hamza Warsame, a Seattle teen, jumped 6 stories to his death after smoking pot for the first time.  An older friend purchased the high-potency marijuana at a legal pot shop.  Investigators on the case called the 16-year-old’s death an accident, not a crime.  

In 2016, Colorado citizens introduced a ballot to cap the THC at 16%.   The industry objected and used hundreds of thousands of dollars to buy off the petitioners of this sensible public safety suggestion. 

Alex Berenson’s concerns about marijuana and psychosis

A year ago, writer Alex Berenson published Tell Your Children the Truth about Marijuana, Mental Illness and Violence.   The book will become available in paperback on February 18, 2020.

USA Today has published a provocative series on the links between marijuana and psychosis, as well as the problems related to vaping THC.   Although Washington did not ban vaping products, this bill would affect marijuana vapes.
