In a new era where where deregulation of marijuana is a reality in many states, an opioid epidemic is hollowing out blue-collar America, and drivers are feeling more pressure than ever to stay productive, alert and safe, the trucking industry is having to take the drug issue head-on.
From the Pages of Heavy Duty Trucking Magazine:
Part 1: Truckers, Drugs and Safety
Amid national trends such as the rapid rise of marijuana legalization and a continuing opioid abuse crisis, trucking faces some disturbing trends of its own.
Part 2: 18-Wheelers and Weed
The stigma around recreational marijuana usage is increasingly fading away and it is even being touted for its medicinal uses. How will a safety-focused trucking industry deal with this new cultural norm?
Part 3: Digging Into Truck Driver Drug Use
A recent study found a higher rate of drug use by prospective drivers than was previously believed to be the case.
Part 4: Is There a Better Way to Drug Test?
DOT-required urine testing has known shortcomings, but in an industry faced with difficulty finding and keeping qualified drivers, some worry that stricter drug-testing protocols will only make the situation worse.
