Abstract

A sharp rise in illicit online pharmacies (IOPs) over the last decade poses significant threats to public health and safety because the unregulated medicines sold are often of inferior quality with no active ingredients or contain harmful chemicals. American consumers provide a major market for online pharmacies, of which 95% operate with flagrant disregard for the law [1, 2]. This article is based on research conducted by the authors analyzing hundreds of online pharmacies, with particular attention to the payment methods used by IOPs, a problem not previously examined in depth in other studies of online pharmacies. The research concluded that the predominant payment method was cryptocurrency, followed by credit cards and third-party payment processors. Use of cryptocurrency on a significant scale is often indicative of financial crime. We observed significant growth of illicit activity during the pandemic and IOPs followed the same trend as customers turned increasingly to online platforms for all forms of purchases. Unfortunately, the problem of dangerous and substandard medicines sold through IOPs continues on a massive scale in the post-pandemic era. New and dangerous products have joined the offerings initially studied, including counterfeit oncology drugs, weight loss drugs, and other newly developed medicines added to the profiles of IOPs. Therefore, IOPs are an increasingly pervasive form of illicit trade undermining human, national, and international security as well as intellectual property rights, and are often facilitated by an unaware and sometimes complicit financial community.
