What is the difference?
Between pharmaceutical-grade fentanyl and illicit fentanyl?
Pharmaceutical-Grade
Pharmaceutical-grade fentanyl is a legitimate medication produced by pharmaceutical companies that have developed advanced technology to control the quality and maintain the proper dosages of the end products. Pharmaceutical-grade fentanyl is tightly regulated and is safe when administered by professionals as prescribed.
Deaths from overdosing on pharmaceutical-grade fentanyl are relatively uncommon and often involve misuse or tampering of medications.
Illicit Fentanyl
Illicit fentanyl is the black market version of the drug obtained or made by dealers and mixed into pills, other powders, blotter papers and liquids, etc. in “labs” with no quality controls. The risk of illicit fentanyl is two-fold. Illicit fentanyl, often made in Mexico, is not manufactured to the same quality standards as the pharmaceutical fentanyl commonly used for medicinal purposes. The potency of illicit fentanyl found in items sold in illegal markets can vary widely from maker to maker, or even from batch to batch, and the buyers don’t know the contents of what they are getting*. Fake pills are then being made, sometimes with inconsistent amounts of illicit fentanyl.
Fake pills are illegally made in garages, basements, and other clandestine settings by unqualified drug makers who do not ensure the quality or consistency of the dose. When batches of fake pills are mixed, each pill may contain a different amount of illicit fentanyl making the dose of each pill impossible to predict.
These products are not regulated and there is no way to ensure consumer safety. Because of this, use of illicit fentanyl is very dangerous. Illegally manufactured fentanyl is involved in the majority of U.S. drug deaths in recent years.
*One of the other negative aspects of poor quality control is that at times, the “illicit fentanyl” is not actual fentanyl. Within an illicit fentanyl supply, there may be unreacted precursor chemicals, byproducts that form due to poor heating or stirring, etc. Also, the amateur chemists can change the ingredients (precursors) of the recipe to form “fentanyl analogs.” Pharmaceutical grade fentanyl is manufactured under strict, government regulated quality control standards so that precursor chemicals or byproducts that are left over from the synthesis process are removed as the final fentanyl product is purified.
