In litigation
The case has been filed and is being fought in court. There is no settlement, no claim form and no payout yet; many class actions are dismissed or never certified.

- December 16, 2024Case filed
What happened
A proposed class action against distributors of closed cannabis oil vaporizer systems and components. The case appears to allege antitrust violations that affected indirect purchasers of those products. These are allegations in a newly filed case, not proven facts and not yet a settlement.
Do you qualify?
No settlement exists yet, so there is nothing to file and no class definition to check. If the case settles, the settlement will define exactly who qualifies — watch this case and we'll let you know.
How to file
There is no claim to file yet. If this case reaches a settlement, a claim process will open — usually with an official settlement website and a filing deadline.
