| Fentanyl | Schedule II | Respiratory depression; Addiction in days | ~$20–$40 per counterfeit pill |
| Xylazine (Tranq) | Not a controlled drug — veterinary anesthetic, adulterant | Not an opioid — naloxone does NOT reverse it; it still kills breathing; Flesh-rotting wounds (tranq lesions) that lead to amputation | Sold as part of fentanyl/heroin bags |
