Drug dealers are now adding Viagra to street heroin to create a toxicological cocktail that is incredibly dangerous for the heart.
Forensic testing in India discovered that sildenafil, the active ingredient in Viagra, is being used as a common filler in street heroin. This is not just a random additive, but a pharmacologically active substance that changes how the drug affects the body. Combining a potent opioid with a powerful cardiovascular drug creates unpredictable risks for users, including heart failure and severe blood pressure drops. This move beyond simple fillers like starch or sugar marks a dangerous shift in the illegal drug market. It makes the job of emergency responders much harder because they are no longer dealing with a single known substance.
Detection of Sildenafil as an Unusual Adulterant in Street Heroin (Smack): A Forensic Chemistry Case Study from Haryana
SSRN · 6730912
Chemical fingerprinting of illicit opioids has historically revealed adulteration with benign or mildly active substances like coffee, paracetamol, and quinine. However, the introduction of pharmacologically strong adulterants has caused a paradigm change in drug tampering approaches. In this study, the presence of sildenafil in a seized heroin ("smack") sample was confirmed using a dependable, sensitive analytical technique using gas chromatography–mass spectrometry (GC–MS). GC–MS made it simpl
