My lady friend has methamphetamine abuse. She was too embarassed to tell me any more. Can you explain it to me please?

CAGE. Give your lady friend the cage test. C= tried to cut back. A= anoyed when confronted by loved ones. G= guilt feeelings about use. E= must take eye opener first thing at waking up. She already scored 2 out of 4. She has abuse problems.
See abuse. Abuse simply implies the continued use of a substance despite harmful effects. It falls shrot of dependence which implies physical withdrawal or severe obssessions/loss of control over usin a substance. Many non-professionals may mix up these concepts however.
