How do I tell if my Weed has been laced?

I smoke weed often. And I was thinking back to the second time I got high. It was about 7 months ago. I don't know what happened it was just... amazing. But I've never experienced a high quite like that before. Now I'm pretty sure it was laced with something but I don't know. How can I tell for sure? It was a really weird experience. Everytime I closed my eyes I would see lines zipping along changing colors and they would make weird figures like cats and dancing imps. I tried to sleep it off but I was restless. I ate a ton of food, a lot more than I normally eat when I'm high. I would run around my house doing strange things; straightening my hair, changing my clothes multiple times; running up and down the stairs; spinning around; etc. Do you think my weed was laced? How would I know and how can I tell if my weed is laced in the future?
