High-Intensity methamphetamine abuse
The high-intensity abusers are the meth addicts, frequently called speed freaks. Their whole existence focuses on avoiding the crash, and they seek that elusive, perfect rush–the rush they had when they originally started smoking or injecting methamphetamine.
With high-intensity abuse, each successive rush becomes less euphoric, and it takes more methamphetamine to achieve a high. Each high is not quite as high as the prior one. During each following binge, the abuser needs more methamphetamine, more frequently, to get a high that is not as good as the high he wants or remembers.
Tweaking for the high-intensity abuser is still the most hazardous time for confrontation. Tweakers are very unpredictable and short-tempered. The crash is frequently spoken of in terms of I never sleep, or I sleep with one eye open. In a try to appear normal, maybe because of an appointment with a doctor, lawyer, or court official, high-intensity abusers will make themselves take short naps; otherwise, they see no need to come down from the high.
