Abstract: BACKGROUND- New psychoactive substances are very diverse; hundreds exist today. Several schemes exist to categorise them; NPS can be classified into Cannabinoids and Cannabimimetics (1), Phenethylamines (2), Cathinones (3), Tryptamines (4), Piperazines (5), Pipradrol derivatives (6), and miscellaneous substances (7)MATERIALS & METHODS- Observational analyses via multiple internet snapshots will be carried out on the surface web and the deep web. The analyses will be hierarchical and integrative to infer the most popular categories of NPS based on the attentiveness (interest) of web users.RESULTS- Analysis of Google Trends from 2012 to the end of 2016, shows that interest in cannabinoids was the highest (98%), while all other chemical categories of NPS summed up to a tiny fragment (2%). The trends were highly oscillating over the years and shooting up during holiday seasons. Geo-mapping and localisation of the Middle East were not possible (not allowed) via Google Trends, while trends were attributed to four major leading countries of the developed world; US (35%), UK (17%), Canada (26%), and Australia (22%). Cannabinoids and stimulants were also found to be the most popular on the darknet.CONCLUSION- A novel method is proposed in this study; it has been carried out to provide an updated extrapolation on the most favoured chemical categories of NPS. This method is based on a combinatory examination at multiple levels of the surface web and the deep web. Furthermore, this method when potentially combined with data mining tools should provide unprecedented real-time analyses of high quality.
