I just had a look at one of the statistics in the Medical Bureau of Road Safety annual report for 2020. It states that in 30% of the 4,489 tests it did people had more than one drug in their systems. Some 2,241 tests were positive for one drug but 1,409, over 30%, were positive for two drugs in their systems. I presume that is outside of alcohol.
