Have any of you tried this?

Bought these in NYC Midtown last night at some store I don't remember but had a huge pot leaf outside. I had a whole one and didn't feel anything. Am I missing something here? Are these just CBD with a tiny bit of thc? I'm new to using thc so advice is helpful, but please be nice. I was hoping to feel something more noticeable, but maybe I need to try a different dosage or product? Any tips on what to look for or how to use them properly would be great! Thanks in advance for your help!
