What is the difference between methamphetamines and amphetamines?
Both amphetamines and methamphetamines resemble naturally occurring substances, but have different chemical structures. Methamphetamines stimulate the Central Nervous System and produce feelings of focus and euphoria in the user. Because they have gotten a reputation for enhancing focus and performance, these substances have historically been abused by athletes, students, truck drivers, and others in fields that demand extended or intense periods of focus or performance.

What are signs that a person has recently used meth? • Sleepless Periods: Because the high from meth can last as long as 15 hours in some cases, meth users may go many days without sleep. On the other hand, when they come down from their high, they may sleep for 24 hours straight. • Weight Loss: Some users are initially attracted to methamphetamines because of their reported ability to help with weight loss.
