Suspect "thc" liquid uk

So I got some THC ejuice from a reputable source with good reviews. And the thing is I don't think it's weed. There is no trace of the taste of weed and the high is very intense, like incredibly intense. Not necessarily in a good way, I have smoked more than my fair share and I have never had anything like it. The high lasts around 30-50 minutes after hitting instantly with no buildup and after effects last like 10 minutes. I have also noticed everyone I have given it to fiends it like crazy. Like I have never known my close friends smash through juice like this and I am worried. But u feel like I could be overreacting to an intense high?

The juice is in a 10ml bottle with the same thickness as nicotine ejuice (not thick like other thc juice I've had) also after a cartridge leak I discovered a black residue left on the side of the tank

If it’s fiendish like you said, it’s most likely a noid. That’s the first thing I noticed when I started smoking noids. Like super addicting. If I were you, I’d trash that shit. Nothing good comes of it.
