Meth has always beem a popular party drug, and has always entered the country in wild vectors like this. I think what has changed is the DEA is no longer cracking down on illegal marijuana imports aince half the states now have legalized growth in some capacity or another. No sense in shipping pot to Wisconsin or Indiana when every state they border has a dispenseries directly across the state line. The DEA has to show that they are doing something, so they are cracking down on meth now
