Media outlets like High Times and Reason magazines are picking up on something I've been noticing: that the trucker shortage and all the supply chain problems it is causing happened just after the US instituted a National Clearinghouse on drug testing results for drivers, forcing thousands of drivers out of the profession due to off-the-job marijuana use. As the situation is affecting the baby formula supplies, the Biden administration's answer is to exempt drivers from safety requirements over how long they can drive or how much they must rest before getting on the road.
