Fentanyl can be deadly in too high a concentration, or if you’re not opioid tolerant, before using. Just so you know, if you have not been on at least 30 mg of oxy or 60 mg of morphine, per day, first, applying that fentanyl patch could kill you. (Naturally, in a hospital setting it can be safely administered).
Thanks, I knew there was a reason I didn’t use it.
