I have been on subs for years and I love the buzz I get from them. I guess I am not the average person when it comes to bupe because I will do 2mg shots of tex iv'ed and get rocked almost every time especially the first shot of the day! If I hit a new vein I haven't really used before I seem to get even higher. It comes on strong and I start just lightly nodding, then I just sit and stare at the ceiling for like 20 mins zoning out, and then comes the energy boost. It is a very weird feeling but it gets me high for sure. it might be because I take kpins everyday along with it? I prescribed to both. And I get a different high from every ROA. From strongest to weakest for me in this order. IV>Plugging>Sniffing>Sub'l. These days I honestly prefer to not blow all my money on dope and other opis and just do my subs. I truly love them. That's just my opinion though.
