I'm pretty sure a lot of folks looked, I did (unsuccessfully). Does it have anything else printed on it like VG/PG percentage? That might help you find something similar or fairly close, blueberry is a common flavor, not one I'm fond of, but you should be able to find another blueberry you like, if you like this one.
I didn't see anything on the pic to indicate that it was poisonous or laced with something. I guess it comes down to whether you trust the person that gave it to you? I mean, for all you know at this point it could be DIY e-liquid (some folks print out some pretty nice labels.)
If you are unsure, find another blueberry from a company you know and start with that. I'm highly doubtful that your friend would give you something horrible or dangerous, but you know that person, not me.
When in doubt, I usually say don't vape it if you are unsure. Why not go to a B&M that does their own e-liquids and taste test some stuff and go from there, if you are unsure. E-liquid doesn't have to be ungodly expensive, even less so if you wind up moving on to DIY e-liquids. It's not the end of the world if you can't vape it, unless you are in a country where getting e-liquid is difficult/dangerous/illegal etc.
Best of luck,
