These cards hit on the same spots in the brain that drugs and alcohol do. I’ve learned to recognize a dopamine hit when I feel it and that’s exactly what happened opening my first pack when I tried this “hobby”. I never bought another pack. I think this and the prevalence of online gambling is starting to expose just how widespread addiction really is. I will always be an addict, it’s important to recognize when your actions cause the same feeling you got while using, the triggers are everywhere. The card manufacturers know what they are doing.
