I'm realizing this too. I think our little world has been protected by obscurity and just how difficult it is to explain to people what these compounds actually are and how the whole thing works. It's really hard to talk about. The occasional times when conversation veers to where it would be appropriate to bring the whole psychedelic RC world up, I usually bite my tongue because it just turns into some awkward monologue on chemistry, shulgin, grey markets, and so on. I think 90% of the time the other person just thinks I'm some kind of lunatic for taking drugs from the internet.
There are very few people I've been able to share this with, it's just too hard to bring up. It seems like most people who take psychedelics could care less about some novel LSD variant and they just want "the real thing", and then people who are more curious or scientific might be very hesitant to consume some weird chemical from the internet.
I suspect we're simply a rare breed personality wise. I'd be curious about other people's experience with this.
