Marijuana businesses are suing Michigan over a new 24% wholesale tax on marijuana set to start Jan. 1st. The Michigan Cannabis Industry Association says lawmakers didn’t have enough votes to pass the tax under state law and want a judge to block it. The tax, part of Gov. Whitmer’s $2 billion road repair plan, could raise $420 million for local roads but may force dispensaries to cut jobs. State leaders insist the tax is legal, while industry reps warn it could hurt an already struggling market.
