the lollipops are for children actually... cancer breakthrough pain treatment in children, hence the lollipop format for 'fun' so kids dont feel scared. I dunno, I saw a photo of a kid sucking one, so I assumed thats what Actiq was mainly for, and duragesic and IV fent were more for the grownups. Ive had IV fentanyl, and found it enjoyable... although my O2 saturation lvls were constantly dropping to unsafe lvls (had monitoring) and I needed to be reminded to breath deeply, it was still euphoric, I had no nauseau develop neither. Also, that shit is the real deal when it comes to killin pain. Couldnt feel nuttin despite cups of blood blowin out my mouth. My intense respiratory depression was more or less due to the fact I was given a much larger than recreational dosage, for a prolonged period of time through an IV plug.
