If a dependent user reduces or stops use of the drug abruptly, they may experience severe symptoms of withdrawal. These symptoms, which can begin as early as a few hours after the last drug administration, include restlessness, muscle and bone pain, insomnia, diarrhea and vomiting, cold flashes with goose bumps (“cold turkey”), kicking movements (“kicking the habit”), and other symptoms. Users also experience severe craving for the drug during withdrawal, precipitating continued abuse and/or relapse. Cocaine is produced from coca leaves. These leaves are stripped from the plant and crushed, chopped, and/or pounded and mixed with a solution of alcohol, gasoline, kerosene, or some other solvent that will separate the cocaine from the leaves. The behavioral impact of habitual heroin use is generally devastating. Most habitual users are incapable of concentration, learning, or clear thought. Rarely are they able to hold a job. They are apathetic, indifferent to consequences, and unable to sustain personal relationships. For many, the inability to honestly earn enough to meet their drug needs leads to crime. For the overwhelming majority, compulsive use prompts behavior that is self-destructive and irresponsible, often antisocial, and characteristically indifferent to the injury, pain, or loss it causes others. The various physical effects of methamphetamine include, increased energy, change in libido, increased sweating, decrease in appetite (anorexia), insomnia, dilated pupils, tightened jaw muscles (trismus), teeth grinding (bruxism), itching, nausea, vomiting, diarrhea, shortness of breath, involuntary body movements (twitches, grimacing, lip smacking, etc), increased heart rate, increased blood pressure, vasoconstriction, dry mouth, and a difficulty in urination. Serious physical effects include, possibly fatal lung and kidney disorders, possible brain damage, lowered resistance to illnesses, liver damage, heart attack, and stroke. |
