A "bad taster" is a synthetic form of acid sold in blotter form. This includes research chemicals such as 2c-i, 25-i, 2c-t-2, 2c-b, 4-doc-dmt, etc. These research chemicals will harm the brain much more than "true lucy" will, or in other terms, LSD. It is a similar experience, but from my personal experience, it's just not the same. If you want to save a few brain cells, spit out the tab if you happen to get a Bad Taster.
Me: "Yo Trevor, I picked up some tabs! Lets fucking fry dude."
Trevor: "Bruh, these are bad tasters!"
*silence*
Both of us: "Fuck it!"
