^He is correct.
Assuming you already haven't gone ahead and tried it... BE CAREFUL WITH OPANA. It is an OC... And way, way more potent than you would ever think. I cringe so badly at all the stories I have read about kids being stupid/careless and not doing their research on Opana properly and just like crushing a pill or half a pill and sniffing it.... then almost dying.
First of all like ihatepipes said, definitely invest in a callus shaver pedicure tool that you can get at a CVS or any equivalent drugstore for like $5-6. Don't use a razor or use any 'normal' pill crushing techniques. You will immediately see why this extra little purchase is your best friend. Opana is not like other pills, and does not "split" or "chip" off well... it just crumbles. Also even though you can take a pretty high amount of Oxy, you still don't want to be breaking chunks off the pill (if you can manage to do that) like you would with an OC 80 or something and railing fat lines. The very sharp, small metal grader that comes with the foot/callus-ped tool is easily pulled right off the plastic tool itself, and then you can start grating away corners/sides of the Opana.
- Even though your tolerance is obviously pretty high, start small... smaller than you think. You can always take more. I have what sounds like about half the tolerance of yours... and when I had 40mg Opanas, I started with ridiculously small lines. Like so small that I couldn't imagine that they would get me high at all... since I was used to pretty much only blowing Oxy. But it did. It got me blasted.
- WAIT AT LEAST 15 MINUTES after blowing your first/each line of Opana. I emphasize this so much because here is where most kids fuck up and end up really, really miserably sick for like 4-12+ hours... or occasionally end up in the hospital. It is a quite intriguing drug in this way. After blowing your line softly (the oral BA is horrible around 10%), unlike almost all other substances you would insufflate, you really won't feel anything for at least 5 minutes, but in my experience more like 10 minutes. And it takes longer for the full effects to come in... I usually give it at least 20-25 mins between lines to be safe. It's super easy to be impatient and be like "what the fuck! This isn't even doing anything, shit is weak!" and blow another line, or two... then end up merked on the bathroom floor. I find that there is a much finer line with Opana between a really nice high and being too fucked up/getting sick, anyone else concur?
You would probably be good off of 1/4th of your 30mg pill considering your tolerance. Definitely no more. It's hard to judge how much you are doing, especially when you are grating it (the proper way to handle Opana). I personally just used the octagon shape and started with shaving off just one full little corner (mine were 40mg ER once again), and then from there quickly started being able to use my eyes to pretty accurately size my lines.
It is definitely more sedating than Oxycodone... and a fuck of a lot stronger. Actually probably the best value in the prescription opiate game hands down... if you consider how far one pill will take you and the comparably cheap cost. Some people really don't like it, but I think it's quite wonderful as long as you don't overdo it. That being said, I would take the equivalent amount in Oxy anyday over it though. I kept hearing how easy it was to get sick and that sketched me a lot... but I never did luckily. I only overdid it once: the last 40mg pill I had, was real comfortable with sizing my lines by then and just got cocky and decided to shave the rest of what was remaining..... ended up with quite a bit more powder than I had thought.. cut it into 2 lines, just did one at first... but then decided I might as well do the other, and blew it just as I was starting to feel the first. Wow, it was as if I smoked 20 fat blunts back to back of the strongest bud or something.... and this lasted for a while, uncomfortably.
- oh and yeah, what was said about it raising your tolerance very fast? Definitely true. I went through just 3 of the 40mg ones in a small but reasonable time period and then got ahold of some Oxys a day or two after my last Opana.My tolerance had almost doubled.
