I've been surfing a bit, but alas I couldn't find the info I wanted to know, so I thought I'd post a thread here and see what comes out of it. Help highly appreciated. Last night I've used speed (Amphetamine) for the first time and after snorting quite a bit (alot of small lines), I suddenly felt my heart beating in my throat and I experienced a slight opressive feeling. Sometimes (I think it happened about 7 times in total) it felt as if my heart was beating two times in a row, andafter that holding a small pause, and then continuing its' normal (very fast and very hard) beating. Like this: boom, boom, boom, boom-boom, ... ... , boom, boom, boom. The feeling can be felt in my throat mainly and it wasn't that I was scared that I wouldn't survive it, but I'm just curious as to how bad this is, and what it is, exactly, and if anyone ever experienced something simular (?). In general, I'm just very curious how bad Amphetamine is for your health, because I can't really find any articles about it. Alot about XTC, yeah, but none about amphetamines => Arg. All I know is that it withdraws lime, and that, if you overdose, you can get a heart attack or something of the likes. Well I'm not specifically interested in how much % there is that it will kill me, I just want to know really if it's safe to use it once a week or so, maybe twice.. I hope someone can answer my questions. Thanks in advance.
