The anti-marijuana legalization committee headed by Gov. Charlie Baker, Mayor Martin J. Walsh and House Speaker Robert DeLeo today will publicly urge backers of the legalization measure to come clean about the high potency of the drugs the measure would legalize – and acknowledge that the marijuana industry depends on these high-octane pot products to make a profit.

The Campaign for a Safe and Healthy Massachusetts cites claims in a legal challenge — currently pending before the state’s highest court — alleging that the marijuana legalization ballot measure is based on misleading information about the potency of the drugs it would legalize. They include edibles such as pot cupcakes and candy and other highly concentrated forms of marijuana that some opponents call “cannabis crack” due to high amounts of the THC, chemical responsible for the weed’s high.

“People deserve to know that this ballot question would allow the industry to market and sell a drug that is much more potent than what existed even a generation ago,” the committee said in a statement to the Herald. “It will also unlock the door for the sale of dangerous edible products that are a risk for accidental use by children.”

The committee is not a part of that legal challenge, but it has echoed the concerns cited by challengers in their lawsuit.

While marijuana cigarettes from the 1970s had single-digit percentage levels of THC, most today have a content of 13 percent or higher, the suit states. Other products, the lawsuit claims, can have THC levels as high as 90 percent.

The committee also cited a statement this week by the head of Colorado’s marijuana trade association in Marijuana Business Daily that outlawing products with THC levels of 16 percent or higher “literally would gut” the industry.

“People deserve to know what they are voting on, and the marijuana industry should acknowledge what it openly admits in Colorado – that its profits depend on high potency products,” the committee said today.

The Supreme Judicial Court is set to her arguments on the legal challenge on June 5.
