Have you not gone to seek medical attention?
There is really nothing to shed light on other than you should never smoke the stuff again related to the adverse reaction you had.
Please seek medical attention about this.
On the contrary, there is something out there that is being sold legally that is being CALLED a safer alternative and is being sold as a legal marijuana substitute. It is a bad idea to even promote the artificial stuff as a safer alternative. Usually, the motive behind such promotions is about the seller making money and not about the safety of the people buying the product. That's generally true of the illicit drug trade, too, so you get the idea.
And, yes, you are correct that it is NOT true marijuana. It is absolutely NOT marijuana. But, it is something sold as a legal substitute.
There is no such thing as fake weed. Weed is weed it's grown n smoked in its natural form. Whatever u had taken possibly cud have some type of ingredient that made u expirence what u had gone through. Have u gone to ur PCP?
I saw a documentary that said that the fake stuff is far worse than the real stuff. You did well to get off the real stuff, and I don't think your body is going to accept the real stuff after having such a major seizure. So, for your own good, don't touch any of it ever again.
Did you have a seizure after the one you just mentioned, or is that the only one? Hopefully, it's the only one and you won't ever try that stuff again.
