Reading up on the differences between lsd and nbomes should shed a lot of light on that problem. The duration is probably the biggest giveaway, which aligns with the timeline of the effects from each.
Since when did nbomes become prevalent anyway? I've had access to lsd since the early 2000's, and I'm positive I've never ran into an nbome. Some of my friends are a lot smarter and more knowledgeable than I am, and even they say that they could tell if a tab is legit lsd or not. Well, if test kits and experience combined are considered reliable factors, which I think they are.
I also need a new test kit myself. I refuse to take something which I'm not 99% sure of what it is. A cautious approach is needed when venturing into this territory.
But I'm done with lsd particularly. I'm also not too keen on continuing illicit use (even occasionally) past this year anyway.
It's been a blast though.
Oh, and lsd isn't going anywhere as long as there is a demand for it. Stupid nbomes though. They remind me of dirty pills being passed off as mdma. If everyone is mindful and takes precautions, people should be able to snuff out nbomes eventually.
Unless of course, people actually like that crap. -_-
