LANSING (AP) — A Michigan judge temporarily blocked the state’s weeks-old ban on flavored e-cigarettes Tuesday, saying it may force adults to return to smoking more harmful tobacco products and has irreparably hurt vaping businesses.

Court of Claims Judge Cynthia Stephens put the prohibition on hold until “further order of this court.” The preliminary injunction will be appealed by Gov. Gretchen Whitmer, who ordered the creation of the emergency rules in a bid to combat the epidemic of teen vaping.

The judge said two businesses that sued showed a likelihood of prevailing on the merits of their contention that the rules are procedurally invalid, because state officials did not justify short-cutting the normal rule-making process.

“Thus, and at this stage of the litigation, defendants have undercut their own assertions of an emergency by the fact that they demurred on taking action for nearly a year, and in the case of some information even longer than that, after they were in possession of the information cited in support of the emergency declaration,” Stephens wrote.

She also said improved health outcomes for adults who switch to vaping products from combustible tobacco “could, and likely would, be lost under the emergency rules.”

Several states have banned the sale of flavored vaping products amid a rising number of vaping-related lung illnesses and an epidemic of teen e-cigarette use. As of last week, vaping-related illnesses in the U.S. had reached about 1,300 cases in 49 states and one U.S. territory, including at least 26 deaths.

Most who got sick said they vaped products containing THC, the marijuana ingredient that causes a high, but some said they vaped only nicotine.

The Michigan lawsuits, which were consolidated, were filed by Houghton-based 906 Vapor and A Clean Cigarette, which has 15 locations across the state.

“We are pleased today that the court saw the ban of flavored vaping products for what it truly is: an overreach of government into the lives of adults,” said Andrea Bitely, spokeswoman for the Defend MI Rights Coalition, a vaping industry group. “We are ready to work through the normal legislative process to arrive at a balanced solution that protects the rights of adults to use vaping products as an alternative to combustible cigarettes and at the same time get these products out of the children’s hands.”
