They actually do that Ren, actiq, its called, a delivery system for fentanyl, the Mu-opioidergic agonist, never had one in that form, but they are exactly what they sound like. Fentanyl-impregnaged lollies. Smack candy. Never actually had one myself, but I wouldn't bother more than once, for the novelty factor, probably having had it transdermally and via IV. I've not liked any of the fentanyl family much, bar maybe alfentanil and lofentanil. They tried putting me on the regular vanilla edition (as in bog standard fent rather than flavour, afaik they only come in one flavour)
https://en.wikipedia.org/wiki/Fentanyl#LozengesI'd probably taste it once and any spares or the remainder I'd keep as a collectors piece type item, or reserve it for emergency. Because despite being around 100x the potency of morphine on a weight basis, fentanyl blows ass. And thats not just my opinion, plenty of people seem to think the same. Oral, up the arse, IV, IM/SC (that is to say, a missed shot, not quite sure which route, probably some of both), transdermally, it really sucked. Same went for sufentanil and remifentanil (especially the last, as its meant for IV infusion, and to wear off minutes after administration, primarily for surgical anaesthesia, its the ultimate prick-tease unless (and never tried, in exogenously sourced form) beta-endorphin or other opioidergic peptides which last seconds to minutes also generally before being cleaved a new arse via enkephalinases and similar enzymes. But think about the duration of a male orgasm then gone)
Fentanyl doesn't have much going for it other than surgical anaesthesia or refractory non-neuropathic pain. In the recreational sense, its THE shittiest opioid I've ever tasted bar remifentanil, the entire family suck really, at least, out of fentanyl,remifentanil, sufentanil, alfentanil and lofentanil. The last two were the only ones I'd really enjoy repeating, and the last I probably wouldn't, as its extremely potent, and too likely to end me, or more likely, kill those handling my dead body or entering the area it was dosed in if it were indoors.
Short acting family of opioids with an atypical binding mode compared to most MOR agonist opioids, and functionally selective compounds such as herkinorin and IBNTXA (iodobenzyl or iodobenzoylnaltrexamide, forget if its benzyl or benzoyl, but its a biased agonist that results in very little recruitment of beta-arrestin, like herkinorin, a semisynthetic derivative of one of the salvinorins, salvinorin-B IIRC, derived from the diviner's sage, Salvia divinorum, a potent and outright weird fucker of a hallucinogen, acting rather than most such compounds do on serotonin 5HT2a or NMDA type glutamate antagonism, on the kappa-type opioid receptor as a potent and selective agonist, most unusual in that its a terpenoid and utterly devoid of nitrogen, unlike almost the entirety of the rest of opioidergics for either MOR, KOR or DOR, and presumably zeta and epsilon. and whatever the hell the lambda binding site is (this is...difficult to find out, it seems due to the receptor protein converting from a high-affinity to a low affinity state upon processing of brain material, but given the nature of opioid receptors, endogenous ligand is probably a peptide, and zeta is...just odd. A growth factor type receptor that has some sequence homology to other opioid receptors, and otherwise jack shit in common with anything either a layman or a neuroscientist would think of as opioid-like, mu- delta- kappa- or ORL1/nociceptin etc.
As for fentanyl itself, its short acting, highly potent and induces a whopper of a tolerance very quickly, plus extremely provocative of tachyphylaxis (short-duration high intensity transient tolerance upon relatively little exposure to the drug or its relatives, in addition to its classic opioid tolerance) and its cold, euphoria-devoid, and but for extremely refractory pain, morphine beats the shit out of it any day. Yet too many clandestine chemists are aiming to synth the stuff, despite its danger. And its ending up in street H as well, one more reason why bar a few times, I don't touch the stuff from the street. Got what I'm pretty sure was either fentanyl or its relatives of some kind-doped H a couple of times. And whilst I could generally speaking use several street-serving wraps intravenously, if I cared to do so, this particular stuff, SMOKED, a single bag, dosed a few specks at a time, lasted over a week. In fact, that was before even refilling my pipe more than a couple of times. Scared the piss out of me to be quite honest, and if I didn't have a tolerance to opioids of the MOR agonist type as a chronic pain patient, IMO I'd have been killed, at least, if it wasn't for my awareness of fentanyl and similar ultra-potent opioids. Its telling, that since it arrived on the local area, every contact, user and dealer, within two weeks, disappeared utterly. Uncontactable forever more. Dead, I think. If I'm not mistaken, then that stuff wiped out the lot of them within two weeks. Of those I know to have handled it, I'm the only one left alive for certain. The stuff had H in it, I could taste it in the vapour, and I'd know the taste of H and opium anytime. But in quantities so small that even pharm-grade or analytical standard-grade pure diamorphine, or home-cooked diamorphine starting with pharm grade morphine and acetic anhydride or acetyl halides, wouldn't have been feelable whatsoever, this stuff knocked me out cold several times. And to do that it takes around a half to one gram of IV morphine sulfate. Whereas this...shit...strong shit, but shit still, despite it being so shockingly potent, a dose sufficient to provoke a total KO was, by eye, around the size of the pyrotechnic composition on the end of a single match stick, if scraped off, and whilst I don't go in much for H, dipropionylmorphine, in pure form, uncut, and to the latter can be vouched for with utter, complete certainty, having witnessed every moment from morphine sulfate, synthesis and administration without it ever having left my sight, and which is around 7-8x to 10x the potency of pure diamorphine, wouldn't do much in the doses taken to such dramatic effect. Stuff is a plague for street users IMO. Better plague than The Plague, (as in the Black Death) granted, but still a plague.
