Drug info - Speed first timer

[Pickpoke]

Ok so swim has been reading about speed, but isn't sure of what it actually is..swim is thinking its similar to coke (which swim has never done) and also similar to Adderall (which swim has done in doses of 90mg in the past). Swim doesn't like Adderall though because it makes him shaky (more often than not) and sometimes gives him red patches on his skin which is icky lol. Swim does not want to try coke because he heard that its one of the most addicting and expensive drugs around, and only last for a short period. Swim started looking into speed, because he feels he needs that extra boost for work because he usually feels worn out. Swim has done OC to get the boost before, but finds himself nodding later in his shift..Swim has never heard any of his friends talk about it, so he isn't to sure about the avalibitly of speed in his area. What swim wants to know is the duration of speed, how addicting it really is, how bad the crash is if any, and the popularity of it in the United States. Thanks!
