| Nida.nih.gov http://www.nida.nih.gov/PODAT/PODAT4.html#FAQ2 Nearly all addicted individuals believe in the beginning that they can stop using drugs on their own, and most try to stop without treatment. However, most of these attempts result in failure to achieve long-term abstinence. Research has shown that long-term drug use results in significant changes in brain function that persist long after the individual stops using drugs. | |
| HelpGuide.org http://www.helpguide.org/mental/drug_substance_abuse_addiction_signs_effects_treatment.htm The path to drug addiction begins with the act of taking drugs. Over time, a person's ability to choose not to take drugs is compromised. This in large part is a result of the effects of prolonged drug use on brain functioning, and thus on behavior. Addiction, therefore, is characterized by compulsive, drug craving, seeking, and use that persists even in the face of negative consequences. | |
