Re: Sounds like it could be
"The article made no mention of drug driving, which I gather is increasingly common."
The laws are written as "driving while intoxicated" so it can be cough medicine, a prescription drug or anything else. In the US there is also "driving while impaired" which is a lower standard and can include fatigue. It's all a problem and just detecting alcohol is going to be an expensive bit of kit that has to be maintained and likely tested/calibrated from time to time at a cost.
