What are Novel Psychoactive Substances?

March 11, 2025

Since OARS opened in 2015, we’ve worked mostly with patients who have an opioid use disorder. Through our experience we’ve have learned that many of our patients develop a co-dependence to other substance use disorders as well.

Novel Psychoactive Substances (NPS) are a diverse group of chemicals derived from naturally occurring plants that possess psychoactive properties and synthetic substances (man-made, modified chemicals) that are created to mimic the psychoactive effects of federally scheduled, illegal, or illicit drugs. These chemicals vary significantly in both potency and toxicity, have not been studied, and unsafe because the scientific and medical societies do not know much about them, and are re highly addictive and significantly psychologically or physiologically dangerous.

Clandestine manufacturers of the synthetic substances develop them as “new” drugs to replace those that are illegal or banned. New chemical structures of these drugs are constantly changing to try to stay ahead of the law. With each new chemical structure comes a new drug that is unstudied and unregulated with potency and toxicity characteristics that are unclear to the maker and the user. These chemicals do not come with a package inserts or recommended dosages and they tend to change in character from batch to batch produced.
