Most pills sold on the dark web are not genuine pharmaceuticals. Law enforcement has caught countless vendors making their own tablets with pill presses, stamping them with real drug logos, and selling them as Xanax, oxycodone, or Adderall. Some are made with raw ingredients shipped from overseas; others are mixed in makeshift labs with no quality control.
The danger is what’s inside: pills advertised as painkillers often contain fentanyl, and fake Adderall tablets have been found packed with meth. Even if a pill looks real, its contents may be wrong, too strong, or contaminated. A single counterfeit dose can be deadly.
