Authorities are reporting an alarming increase in the number of methamphetamine seizures at border ports of entry.

In Arizona, U.S. Customs and Border Protection officers seized over 3,240 pounds of meth between October and May, already surpassing the amount seized in all of the last fiscal year. The federal government's fiscal year begins Oct. 1.

Southern California ports have also seen a spike in both meth and heroin at the border. Heroin seizures have more than tripled since 2009.

Officials say Mexican drug cartels have proliferated in the meth market after the U.S. cracked down on over-the-counter medications used to make the drug. There were fewer meth labs in 2014 than in previous years, according to the DEA.

Drug smugglers use creative ways to get meth into the U.S., such as liquefying it to avoid detection.
