So yesterday I smoked some weed, not very much, and this was only like the 4th time I've ever done it. Shortly after, I started having some trouble catching my breath, and my heart started beating kinda irregularly. By that I mean it would beat really fast when I wasn't even moving, and then suddenly start beating slow. Also, I can feel my heart beating really well without feeling my pulse. I sometimes get anxiety attacks so is it possible I'm blowing this a bit out of proportion? I'm just worried because I'm still having trouble breathing and I smoked yesterday. Oh by the way, I did it out of a tin foil pipe that I made - stupid, I know. But I don't think doing it once out of that kind of pipe would do that much harm right? Because I know lots of people who have smoked using tin foil and they're all fine. And another thing, I smoked this same weed like 3 days ago out of my friend's glass pipe and didn't have any breathing or heart problems.

Any help is appreciated, thanks.

So I'm 5'10 at 15 years old and I'm worried I won't grow anymore in height. My older brother is 6'3 and my dad is 6'2 so I really hope I can grow more. Apparently I'm supposed to be 6'1 at full height but it seems like I haven't been growing much in the past year. What do you think, is it likely that I'll grow any taller?
