Mexican drug lab

MEXICO CITY – Mexican marines on Friday said they had discovered an underground drug lab in the mountains outside the capital of Sinaloa state where they destroyed 50 tons of methamphetamine.
Marines found the lab after intelligence reports indicated that tons of drugs were being produced in the area of Alcoyonqui municipality, about 12 miles outside the state capital of Culiacan, the ministry of the navy said in a statement.

As of Aug 2018, but the purity and quantity has since increased. And the question unanswered, if they make it in Mexico then why ship out of Long Beach?
