Research has shown that acupuncture stimulates circulation and the release of endorphins and influences neurotransmitters, the autonomic nervous system, and electrical currents in the body – all of which directly affect how the brain and major organs function. In addition to general positive health effects, acupuncture is also well-known to assist those with chemical dependency. The NADA protocols use auricular (ear) points to help those suffering detoxification symptoms to relax, particularly when feeling most ill from withdrawal. The benefits of the NADA protocol include reductions in drug cravings and anxiety, better sleep, less need for pharmaceuticals, and greater willingness to see drug treatment through.
