Weitz & Luxenberg has filed class action lawsuits against multiple manufacturers of cannabis products. We have filed these suits on behalf of clients in states across the country who were harmed by the fraudulent and deceptive marketing strategies employed by these companies.
You may be eligible to join one of our lawsuits if you purchased a cannabis product from these suppliers in the last two years and you relied on false representations that recreational cannabis products have medicinal properties.
Our class action suits were filed on May 4, 2026. Defendants in these class action lawsuits include Cresco Labs Inc., Green Thumb Industries Inc., Verano Holdings Corp., Verano Holdings, LLC, and Curaleaf Holdings, Inc. The lawsuits were filed in three different courts: the United States District Court, District of Connecticut; the United States District Court, the Northern District of Illinois; and the Circuit Court of Madison County, State of Illinois.
If you or a loved one suffered serious mental or physical health complications after using cannabis products, you may have a legal claim.

“At the crux of it, our claim is about consumer protection. These manufacturers make representations about health benefits that are unfounded while failing to warn about health risks,” explains W&L partner James Bilsborrow.
“The defendants boast that their products help with anxiety, sleep, and other health problems. Many of these supposed benefits are unfounded. At the same time, these manufacturers provide no warnings about the very real potential for serious mental health harms. Cannabis-induced psychosis is just one significant danger,” Mr. Bilsborrow adds.
In general, the class action claims are for consumer fraud. The suppliers’ actions led to economic harms because they sold products that simply don’t have the qualities the manufacturers represented. Separate charges named in our suits include fraud, racketeering, negligence, strict liability, failure to adequately warn, breech of express warranty, and unjust enrichment.
Deceptive Marketing Tricked People
These companies didn’t just lie on their product packaging. They promoted their products far and wide on websites, social media, and blog posts. They instructed their employees to misrepresent the benefits of their cannabis products. Employees at dispensaries were also expected to tout the healthful qualities of their cannabis products to customers through personal interactions.
False and misleading statements came in the form of in-store conversations with so called “budtenders,” telephone conversations, and online chat features on the suppliers’ websites. According to the companies we are suing, cannabis products could alleviate everything from depression to glaucoma, epileptic seizures, and pain.
These companies not only sold the cannabis products, they actually strategically created the cannabis market. Their only goal was to increase sales.
Consumers who purchased cannabis products marketed with misleading health claims may have legal options. Contact Weitz & Luxenberg to learn whether you may qualify to join ongoing litigation.
Get a Free Case ReviewCannabis Products Can Be Dangerous
The cannabis products sold by the defendants have one main thing in common: tetrahydrocannabinol, or THC. At high concentrations, this chemical is highly dangerous.
These companies knew, or should have known, their recreational cannabis products were not approved by the U.S. Food and Drug Administration as a treatment for any single medical disorder. Also, no reputable, credible, scientific research has shown that recreational, high-THC cannabis is safe and effective for treating anything.
In fact, the exact opposite is true. Medical research has shown that using cannabis can cause or make certain mental health conditions much worse. People who use cannabis can develop psychosis, schizophrenia, depression, bipolar disorder, suicidal ideation, anxiety, and panic.
In addition, people who use cannabis can develop other serious health problems, including heart attacks, stroke, cannabis hyperemesis syndrome, and cannabis use disorder. Cannabis can also be risky during pregnancy and endanger the developing fetus.
