First time I got high, it was sort of what this guy is describing. It was about 5 minutes after smoking, and it was like I blacked out, and then came to realization that I was fucking stoned. After I got used to it, me and all my friends did all the normal stoner shit, only it was funner b/c none of us had been smoking for a while, so it was all pretty new. I stayed high the entire day, and the next day I had a sudden flashback that lasted for a few hours. Over the next few weeks I would have short flashbacks, maybe like 30 mins at a time randomly.

That's the only time it was ever like that though...and I was 13 lol.
