why do i feel laggy when i smoke?

I smoked some weed with my buddy's, it was a cart, and about 20 minutes after i smoked the weed, i felt like my body was lagging. If i touched something i felt like a second after i actually did. This feeling lasted around 5ish days. Every now and then i feel this same exact feeling and i start to panic a bit. I didn't feel hungry or giggly like everyone else does. I went to Chicago for a trip and I got a disposable because i wanted to try it again and the same exact thing happened and it lasted 3 days. any other people have a similar experience? I want to smoke again to see if i get giggly and all of that, but i'm scared this "lagging" will happen for multiple days at a time again. I really want to enjoy it. Someone help!
