It is unlikely that a perfect drug candidate will emerge from these early screening runs. One of the first steps is to screen for compounds that are unlikely to be developed into drugs; for example compounds that are hits in almost every assay, classified by medicinal chemists as "pan-assay interference compounds", are removed at this stage, if ...
Pliny the Elder, who lived from 23–79 CE, first gave a name to what we now call pills, calling them pilula. [2] Pliny also wrote Naturalis Historia a collection of 38 books and the first pharmacopoea.

Drug checking or pill testing is a way to reduce the harm from drug consumption by allowing users to find out the content and purity of substances that they intend to consume. This enables users to make safer choices: to avoid more dangerous substances, to use smaller quantities, and to avoid dangerous combinations.
The SBIRT model was developed by the Institute of Medicine as a result of a recommendation that encouraged community-based screening for health risk behaviours, including substance use. Unhealthy and unsafe alcohol and drug use are major preventable public health problems resulting in 3 million deaths every year worldwide, as reported by WHO. [3]
The above photo shows the positive results of the number 2 Marquis reagent presumptive drug test when used with a sample of opium. It is the primary presumptive test used in Ecstasy reagent testing kits. It can also be used to test for such substances as opiates (e.g. codeine, heroin), and phenethylamines (e.g. 2C-B, mescaline).
In the 15th century, the printing press spread medicinal textbooks and formularies; the Antidotarium was the first printed drug formulary.
