Massachusetts marijuana lab sues rivals over 'fraudulent' practices

A Massachusetts marijuana testing lab has filed a lawsuit accusing eight competitors of “fraudulent” practices of inflating THC potency and manipulating safety results to allow potentially tainted products into the market.

The complaint, filed Jan. 30 by MCR Labs in Suffolk County Superior Court, follows years of allegations in the industry that labs are deliberately falsifying data to please clients and that state cannabis regulators have been unable to rectify the problem.
