Products exceeding these limits or containing detectable THC in food/beverages face restrictions under CDPH regulations.

Is THCA legal in Nebraska? Under the 2018 Farm Bill, hemp-derived products are federally legal if they contain no more than 0.3% delta 9 THC on a dry weight basis. Because THCA is the non-psychoactive precursor to THC in raw cannabis, it can be sold as hemp when it meets this federal threshold.

Consumers should review current Nebraska regulations and confirm that any THCA product is lab tested and compliant with federal and state requirements before purchasing.
