It wasn't very long ago that vaping-induced lung injuries from cannabis products containing THC made headline after headline, even if they were ultimately short-lived after the discovery that many of those issues were due to black market products. Among the many concerns arising from "Vape Gate" was the possibility of persisting impacts on product liability insurance for cannabis companies.

"Bottom line, there is still some apprehension on writing vape or vape-related risks, but insurers are optimistically cautious," remarked Jay Virdi, Hub International's chief sales officer for cannabis insurance and risk services in the U.S. and Canada, at the time. "It is going to take cooperation between the cannabis industry and regulators to get their confidence back."

What other liability issues have arisen in the cannabis space since Vape Gate? Virdi and other experts will tackle that question in our Twitter chat, "Emerging Risks in Cannabis," which will take place — perhaps unsurprisingly — on April 20 at 11 AM EST.
