Profile, effects and toxicity of novel psychoactive substances: A systematic review of quantitative studies

Abstract

Objective: To investigate the profile, effects and toxicity of novel psychoactive substances (NPS).

Methods: A systematic literature review was conducted between May 2015 and February 2016 and included 19 databases. Search terms included: ‘novel psychoactive substance(s)’, ‘effect(s)’ and ‘toxicity’ and their synonyms. Studies included were those from any country, in any language and between January 2007 and April 2015. Studies published before 2007 and those regarding the synthesis of NPS were excluded. Data was extracted by evaluating the titles, abstract and full text respectively. Consequently, the extraction yielded 20 studies.

Results: A total of 43 NPS derivatives of eight main pharmacological classes were identified. NPS were mostly used among young adults and adults within the age range of 16-64 years old. Cathinones and synthetic cannabinoids were the most prevalent amongst the aforementioned classes. The main desired effects of NPS use were empathy and increased ability to socialise. Reported toxicity associated with the use of NPS included cardiovascular, neurological and psychoactive adverse reactions.

Conclusions: Despite the unique subjective effects associated with the use of NPS, harmful effects could be severe and/or lethal. Therefore, there is a need to develop research in the area of NPS and promote awareness among healthcare professionals.
