You really do need to take advice on being more responsible. I am against insufflation of RC's. I am a natural/organic person when it comes to psychedelics, and just the fact of ingesting powder takes 1% of my experience from me. Don't get me wrong, I have nothing against RC's, and I want to continue using them, but I just really like consuming organic psychedelics. Anyhow, with that said, insufflating it would be horrible for me. The 2C's work fine orally, so why do it any other way? The only RC's I would consider using otherwise are DMT and 5-MeO-DMT, which I would smoke or use IM, though I would much rather use Ayahuasca, and DPT which I would use IM. All others that I can think of that I've ever had an interest in work fine orally. How do you know that you got around 15mgs? 2C-E powder is beyond fluffy. I have measured what I thought were around two 20mg piles, and one turned out to be 16mgs, and the other 33mgs. I have also tried eye balling other chemicals before weighing them and have had many other wide range results. I'm not going to come down on you or anyone else though. I have made mistakes with other drugs in the past, but I just try to look out for people now because of that.
I have been talking about 2C-E alot lately. I really want to have a 20mg trip this summer. My 16mg trip had me in a fairy tale. However, I have been taking a break. My last trip was with 25mgs of Iprocin, and that was awesome. I am going to have a mushroom trip soon, and a morning glory seed trip soon, and then I should resume my experimentation with RC's.
