Latest recalls

California cannabis recalls

CHSA monitors recall notices from California’s Department of Cannabis Control (DCC) and links each one to the official notice. Recalls from other states are not covered yet.

How recalls work

Mandatory recall
Ordered by DCC when a product is an immediate and serious threat to life or health.5
Voluntary recall
Started by the licensed business itself. DCC posts both kinds.

Have a product at home? Compare the batch or lot ID on the package with the one in the notice. If it matches, stop using it and follow the notice’s instructions.

We read new studies and explain what they found, how strong the evidence is, and what it means for you.
