There is a book by Roy Eskapa titled"The Cure for Alcoholism: The medically proven way to eliminate alcohol addiction". There have been advances in medicine to help eliminate cravings and block effects of some addicting drugs including alcohol. But anyone that says they have the "cure" for addiction are way off base. The title of this book is selling instant gratification to sell books. If an addict uses a drug to block the effects of addicting drugs that will deter an addict from using that particular drug, but that does not arrest the underlying factors that come together to give an addict an unquiet mind. The addict also has to cooperate and take the medicine faithfully to block the effects of the drug they are addicted to. I have pointed out all along that mostly physiological factors determine if a person will become an addict and also determine what drug will become addicting to the addict. But the unquiet mind which is the underlying factor of all addiction needs to be treated to suspend the addiction. That's right. The addiction can only be suspended not cured. All environmental, psychological and physiological factors that make up an addict must be addressed. By using Naltrexone and other drugs to block an addictive drugs effects, the addict will still gravitate to another drug or behavior. If the underlying factors are not addressed then the addict cannot manage a daily sobriety. Any pills that aid in helping an addict get clean are just that, an aid to helping ease the symptoms of withdrawal and the cravings.
