    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.

    Exploring a Not Very Known Opioid neutral exp #115489

    At the time I had experience with a lot of substances everything from weed to benzos, opiates, LSD, shrooms, 2C-B, ketamine, other pharmaceuticals, etc. Sometime the end of 2020 I bought some etazene (etodesnitazene) of the dark web. When I got it, I sent it a lab testing and got my results and it was etazene.
