Even so, poly-drug use, or detection of numerous drugs in biological specimens from one donor, is usually encountered. Trying to determine the consequences of a single substance to the cumulative effect of drug mixtures is extremely hard, despite what focus(s) could be measured. Furthermore, the put together usage of multiple NSO is usually claimed, including a single situation from Quebec that documented 17 various NSOs, which includes U-47700, U-47931E, N
