Ahamed A, Kullmann KC, Frasso R, Goldstein JN. Analysis of Unregulated Sale of Lifesaving Prescription Drugs Online in the United States. JAMA Intern Med. 2020;180(4):607–609. doi:10.1001/jamainternmed.2019.7514
Reports in the lay press suggest that patients who cannot afford prescription medications seek out discounted products in online marketplaces such as Craigslist.1 The unregulated sale and purchase of prescription medication is prohibited by law and Craigslist policy.2-4 We sought to quantify and characterize advertisements on Craigslist in the United States for 3 potentially lifesaving medications: insulin, albuterol, and epinephrine (EpiPen).
We undertook a mixed-methods, cross-sectional analysis of Craigslist advertisements in the United States. One research assistant (A.A.) individually entered the search terms “insulin,” “albuterol,” and “Epipen” in the Craigslist search engine for each city in each state listed on the Craigslist site. The search was completed in 12 days (June 12, 2019 to June 24, 2019). A 20% sample of collected data was verified by a second researcher (J.N.G.).
Advertisements were categorized by drug type. The price per unit was calculated as the total price divided by the total number of units for sale (ie, $100 for 10 vials of insulin = $10/unit). Mean advertised prices on Craigslist were calculated for all categories of drugs. The difference between the retail price (listed on Drugs.com) and the advertised Craigslist price was calculated. All information was recorded into a REDCap database and all analyses were performed using Excel and SPSS statistical software (version 20, IBM Corp). Content analysis was performed to identify dominant themes of the advertisement text using the approach described by Guest, MacQueen, and Namey.5 One member of the research team (K.C.K.) coded the entire database and a 30% sample was double coded by a second researcher (R.F.). Discrepancies were resolved by consensus. Intercoder reliability was calculated with NVivo statistical software (version 12, QRS International). This study was deemed exempt by the ChristianaCare institutional review board because all data used were in the public domain.
During the study period, all 50 US states were searched, and 432 advertisements for insulin and albuterol were found representing 240 cities in 31 states. No advertisements were identified for EpiPens. We identified 105 (24.3%) advertisements for albuterol and 327 (75.7%) advertisements for insulin. Analog insulin was the most commonly advertised product, with 311 posts (71.9%). Of the analog insulins for sale, the most common were Lantus (n = 91, 27.8%), Humalog (n = 90, 27.5%), and Novolog (n = 70, 21.4%). When compared with the retail price listed on Drugs.com, the Craigslist price for an albuterol inhaler was, on average, $18.77 more expensive than retail, whereas the price per vial of analog and human synthetic insulin were $372.30 and $123.19 less expensive, respectively (Table 1). Content analysis of the text of advertisements revealed 3 dominant themes: (1) motivation of sellers, (2) quality and safety of the products, and (3) sales and shipping details. Sellers were frequently motivated by altruism and aversion to wasting medication. The content of many advertisements raised safety concerns about the quality and safety of the medications being sold (Table 2).
In this cross-sectional analysis we found that analog insulins were the most commonly advertised prescription drugs and were being offered at a fraction of their retail price on Craigslist. Unregulated resale of prescription medications is illegal6 and in the case of insulin, may be dangerous because improper storage can lead to loss of potency or contamination of the product. Although we were unable to obtain the exact details of Craigslist’s regulatory mechanisms, the site does allow users to report or “flag” inappropriate or illegal posts, which are subsequently considered for removal by site administrators. Our findings may not be representative of all advertisements on Craigslist at all times and there is no way to verify whether advertisements resulted in sales of prescription medications. However, this study provides evidence that patients are seeking and likely finding medication, in particular analog insulin, in unregulated and unmonitored online marketplaces.
