After a person stops using meth, the physical and psychological symptoms of withdrawal can occur. Chronic users who frequently take the drug over an extended period of time are most likely to experience withdrawal symptoms.
The withdrawal symptoms of meth are traumatic and painful, and can cause the user to take more of the drug in hopes of counteracting the withdrawal process. However, doing this may lead to a downward spiral of repeated meth use, which can develop into a full-blown addiction. By the time many users realize they have a problem and try to quit, they find that the withdrawal effects have become too powerful to overcome on their own.
