Hemp and Hemp-CBD in California is wild right now.

As readers of this blog know, California is on its way to developing robust laws governing the sale (and all other aspects) of cannabis and cannabis products. So, it’s somewhat surprising that California’s laws concerning the sale of industrial hemp and hemp-derived cannabidiol (“hemp-CBD”), to the extent they even exist, are all over the map. And in some cases, selling industrial hemp or hemp-CBD is apparently unlawful, in spite of the fact that it may contain just trace amounts of THC found in California-legal cannabis products and despite the fact that that hemp-CBD is coming from Farm Bill-sanctioned sources.

Our California cannabis lawyers often get asked what the requirements are for selling industrial hemp or hemp-CBD in California. This post tries to explain California’s convoluted regulation of industrial hemp and hemp-CBD.
