MICHIGAN, (WOWO) — A legal fight is brewing in Michigan over a new 24% wholesale tax on marijuana.

The cannabis industry says lawmakers may have illegally altered the 2018 voter-approved law by skipping the required supermajority vote.

Supporters say the tax will fund roads, but critics warn it could cripple the legal market and push users back to the black market.

The Senate voted yesterday – and a lawsuit may be up next.
