Trust me. My wife and all rural villagers know how the yaba traffic works and exactly which people, entities, and institutions are involved. Meth is big business, big money, and a huge social problem. Most average (non-Meth users) aren't happy about the drug trade nor those involved either. It doesn't end because of the nature of the stakeholders making the money.
Bust the plebs for a couple of pills and the 'authorities' (I use that term loosely) are so busy busting nobodies that those actually involved in trafficking are able to skate.
