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.

Trucking Under the Influence is an investigative series by Heavy Duty Trucking examining the impact of illegal drug use by drivers amid current trends of marijuana legalization, opioid addiction, a rise in cocaine use, and changes in driver drug-testing regulations and technology.
