Addiction is a reliance upon a substance, hence it's also termed substance abuse.
Most people are addicted to something, for example coffee, tea, smoking, chilli. Addiction is only problem when the substance a person is abusing is strong enough to damage their health, for example cocaine, crack, heroin, etc.
There is a growing addiction to opiate based pain killers as they are a mild form of heroin. Unfortunately, people then go onto taking heroin which has disastrous effects upon their lives. This new addiction has been created by big-pharma.
Acupuncture for addition
Acupuncture has been used to help addicts since the 1970's when it was first used to treat opium addicts in China.
Early researchers found that electric stimulation of the lung point on the ear helped to reduce cravings for illegal drugs.
Years later, a doctor in New York, USA developed the NADA protocol which uses 5 points on the year to treat addiction. This new protocol became very popular and was used in drug rehab clinics and prisons. However, it's a standard protocol that doesn't include electrical stimulation of the lung point.
I'm an expert in drug addiction and acupuncture. I've had two papers published on the use of acupuncture to treat drug addiction. One was a critique of research that used ear acupuncture to treat cocaine/crack addiction and the other was an academic paper explaining drug addiction within Chinese medicine theory.
Today, I still treat drug addiction within my clinic with a good success rate. I also look at the deeper, emotional issues of drug addiction that are often the root causes of why people abuse drugs.
