The interstate highway system is heavily used by business interests, shipping goods around the nation. But drug traffickers also utilize the highways to move their goods. The Illinois State Police continually monitors the interstates in search of those transporting the illegal products. Illinois State Police Trooper Heath Bryan says they are seeing a lot more methamphetamine.
He says the increase in meth is likely due to the law of supply and demand - heroin is popular right now, so it's drawing a higher price. That means meth is cheaper, and is starting to gain momentum again.
