^ You are exactly right - buprenorphine has a higher receptor affinity than naloxone, so naloxone doesn't get a look-in. For anyone who wants to read more, the
Suboxone megathread (in OD directory) has lots of useful information on Suboxone.
The reason this myth is so common is that it is perpetuated by healthcare professionals, drug workers and drug companies, and at first glance it does seem to make sense, if you were unaware of bupe's high receptor affinity. The theory they use is that naloxone has a poor oral/sublingual bioavailability, so is not active if the Suboxone is taken correctly, but is active when administered IV (and obviously has a 100% bioavailability via that ROA) which would prevent people getting high from shooting their meds. Unfortunately it is completely useless for anything except making drug companies money
Alprazolam, if you like the feeling of being opiated then you may find methadone maintenance more suited to you - methadone isn't as recreational as a lot of other opioids but you tend to be able to feel it more than Suboxone when you're on maintenance therapy - some users prefer feeling like they are a little intoxicated, even though it isn't the same as a more recreational opioid high, where as others find it too heavy/sedating and prefer buprenorphine (Suboxone/Subutex) which - although it can be recreational - tends to feel more "clear headed" when used as maintenance. Horses for courses though; see what suits you.. a downside of going on MMT if you still love using opioids is that methadone doesn't have such an effective blockade effect, so there may be less deterrent to using on top of your script.
It sounds like you're not really committed to maintenance therapy right now though.. if that is the case, perhaps MMT isn't for you, as methadone can be difficult to come off and I wouldn't really recommend embarking on a maintenance script unless I was serious about wanting to get clean, or if I was coming to harm using other opioids and needed some stability. Have you thought about drugs counselling? I know it's none of my business and I'm really not trying to interfere, but if you do want to make a serious attempt at getting clean then I'd really recommend looking into that.. have a look in "Other Drugs" and "The Dark Side" forums too for more advice on this. Good luck!
