In 1857, with ill-advised opioid usage reaching alarming levels, a parliamentary bill was put forward which classified opium and its derivatives as poisons. This was intended to severely restrict the sale of such compounds, but it failed to pass through parliament, after being subject to intensive lobbying by trading chemists. It was also widely criticised as an impractical solution from an overall perspective. A much-diluted version of the original proposed bill was finally implemented as the
Pharmacy Act 1868 (
31 & 32 Vict. c. 121) which limited the sale of opium derivatives to registered chemists and legally qualified apothecaries. It explicitly excused patent medicines (and thus Godfrey's Cordial) from its purview. Usage of Godfrey's Cordial gradually declined post-1890 as several court rulings held that the act applied equally to patent medicines and the British Medical Association subsequently published lists of safe home remedies, in a bid to increase public health awareness, which mentioned
calomel and sugar-based derivatives as substitute sedative agents. Finally, the Pharmacy Act 1908, which classified it as a Schedule-I poison, followed by the
Dangerous Drugs Act 1920 (
10 & 11 Geo. 5. c. 46) which mandated a medical prescription, heavily restricted the availability and usage of any such opioid-based drug. ==References==
