Speed is a slang word that most often refers to methamphetamine, although it is also a loose term for any illegal stimulant sold on the street. Speed has the effect of increasing energy and alertness. Many people feel very powerful and euphoric when they use it, and may appear happy and overly talkative. Side effects can be dry mouth, picking at imaginary bugs or lint, irritability, diarrhea, blurred vision, dizziness, twitching, insomnia, tremors, dry skin, pallor and hypertension.
