    ☠ Nitazene-class opioids are extremely potent, often exceeding fentanyl in strength. Even trace amounts can be fatal. Naloxone should always be on hand.
    ⚠ Opioids carry significant risk of respiratory depression, physical dependence, and fatal overdose. Never combine with other depressants.
