Blacked out smoking weed

[granny50]

Has this happened to anyone? I took a hit of some KB and then felt really really wierd. My friend told me we had to go and I told him I couldn't move. He told me to stop being a pussy and I followed feeling very weak. I walked outside, stumbled across steps and then was leaning against the wall. The next thing I know Im being carried to the couch and found out later that I passed out and almost killed myself, if it weren't for a guy who caught me before my head hit the concrete steps.
Has this happened to anyone else?
