Oh haha my bad.. I mean as a pretty 'seasoned' heroin user, I would have to agree that anything short of IVing doesn't really provide anything 'mind-blowing', especially if you have any sort of opiate tolerance to begin with. I had snorted heroin for a year or so, after doing oxy for a long while, and yeah it was cool, but nothing amazing.. Had to sniff way too much to even get a nod going. But then after a series of severely negative events happening I started IVing and the first time I shot a couple bags of good NJ heroin, it was all over.. So good job on staying away from the needle. Before I started IVing I was able to keep things under control.. Then as soon as I start shooting literally everything went to a rock bottom I never thought possible, within less than 2 months time.
I have no experience with tar, though, and since you have a decent tolerance in the first place I feel your options are fairly limited.. Your only option really is just to continue plugging, and try titrating the dosage up until you can get something worthwhile out of it. But if you are used to high doses of oxy, then you're probably better off just slangin' that shit and going back to your beloved OC's.
