LSD and taste is a sometimes heated subject. Technically LSD is not supposed to taste like anything at all. However, sometimes the LSD will be in or on a material that has taste. I have had LSD blotters that ranged in taste from almost nothing to making me want to puke from how bitter and chemical it tasted. I had bitter LSD from mostly reputable sources, and this was years ago before anybody online had any clue about nbome drugs. The people selling the bitter acid, which was extremely popular in Europe, gave a few explanations for the taste. One explanation was that it was the ink used on the paper, I don't really buy this though because the US GDF blotter never had taste, even stuff that wasn't WoW. Another explanation was that they used non-chlorine based blotter paper to minimize degradation of product once put on the paper, this excuse makes sense to me because chlorine neutralizes LSD as soon as it comes in contact with it, but I have no idea if that paper has such a strong chemical taste to it or not. The effects I have gotten from bitter LSD certainly felt like they were induced by an ergoloid, although the effects were perceived by many as being slightly different enough that it could have been an analog of some sort. Some of the blotters were actually lab tested and confirmed to have analog ergoloids on them, although this was seen as highly controversial. So in summary, LSD should have no taste to it, but if a blotter has a taste to it it may not certainly rule out it being LSD. I think that if liquid has a taste to it then it is more likely to not be LSD though, unless the taste is minty or the taste of alcohol or whatever.
