Is it normal to feel like i did?

Okay so yesterday I went with a friend to smoke some weed. I've done it before probably about 20 times. But in those times I've done it frequently. But I stopped and yesterday was the first time in about a year. So I took probably about five hits of a bowl (I've only ever smoked out of a bowl). Then about five minutes later I was just getting less and less conscious. I felt VERY tired and lethargic. My vision wasn't really blurred but it wasn't perfect. I remember only being able to focus on one thing and I couldn't pull myself from that object. I tried standing up and leaned against a pillar and remember slowly starting to go out of it. So I went and sat in a couch and passed out for like two minutes, if that, drank some water and thought I was okay. But then I started to fall back into the "spell" if you will, and my friend took me home. Well I don't remember anything about leaving until I had to vomit on the way home. I felt better, only for five minutes maybe then I fell right back into it. She kept trying to get me to talk and respond but I didn't have the energy. I puked one more time and I got home and went right to bed. I literally don't recall hardly anything except for what I just said. And even that is a blur. I still don't feel back to 100%. I don't think it was laced because everyone else was fine. And I know I've smoked more than that before because I only took about five, smaller, hits last night. So I'm just scared and it makes me want to never smoke weed again. Help!
