PRESTON — A Minnesota hemp farmer is facing charges after authorities claimed his products had more than the legal limit of the compound that makes users high.

Court documents say products from Luis Hummel’s 5th Sun Gardens hemp farm in Lanesboro were sent to a lab for tests and found to have THC levels above 3%. The level for commercial hemp cannot exceed 0.3%.

Hummel has been charged with selling drugs and drug possession in Fillmore County. The charges come after Hummel sued state officials who revoked his growing license and ordered him to destroy his multimillion dollar crop because of its THC levels. Unlike marijuana, industrial hemp only has tiny amounts of THC.

Hummel’s attorney, Jason Tarasek, said it was a processing mistake that his client was trying to correct and the product tested wasn’t in the marketplace.
