Two men were arrested early Monday in Fullerton after authorities pulled over a U-Haul truck they said was being used as a clandestine lab for THC oil production, according to police.
California Highway Patrol officers noticed a thick brown liquid leaking from the back of the truck while it was being driven on the westbound 91 Freeway near Brookhurst Road at 1:15 a.m. They stopped the vehicle off the freeway and smelled a strong chemical odor, police said.
When officers looked inside the truck, they found what they initially thought was a mobile methamphetamine lab. A hazmat crew tested the substance and determined it contained THC oil. Tetrahydrocannabinol is the primary psychoactive ingredient in marijuana.
