*Actually, i do not know what is amphetamine salts, and which of medicine including.

*After i post my first message, i did some search to learn how the things going on in US. ı I checked the top US states in a wide range, such as job opportunities, average income, health care quality, social life etc.

*After all, if i can get the visa, i want to live in Des Moines, IOWA.
