Cigarette addiction has long been known to be a difficult problem to solve.  People approach the problem from a biological point of view, or biochemistry, or psychological.  The problem, however, does not require a college degree to solve.  

Addictions such as to tobacco, or to illegal drugs, or to alcohol, or to gambling occur when, by engaging in such behavior, a very undesirable change occurs in the person doing so.  

Unfortunately, some do not believe in God.  That will severely limit their understanding.  He exists whether they believe in him or not.  Satan is a spirit being originally created by God as a good angel, Lucifer.  But he was lifted up in pride and wanted to be worshipped.  When he rebelled against God, some of the angels followed him.

Spirit beings exist in a different dimension.  They don't have flesh and blood bodies like humans, so they are normally not visible.

These fallen angels are called demons, or devils.  Demons are not general practitioners, that is, the demon that tempts someone to rob a bank is not the same demon that tempts people to commit adultery.  There are demons of addictions: tobacco, drugs, sex, gambling, etc.

Pastor Win Worley, of Highland, IN, listed some eleven hundred different demons, and wrote books on the casting out of demons.      

The main textbook on this subject is the Bible, especially, the New Testament.

When a person becomes addicted to tobacco, a demon of addiction gets into that person.  Now what to do to get rid of that demon?  The demon will automatically go out when the host human dies.

Otherwise, to get the demon to go, a Christian must cast the demon out.  Non-Christians will be unsuccessful in casting out demons, and may endanger themselves, as with the seven sons of Sceva in the book of Acts, who got beaten  up for trying to do so without proper authority.  

Christians have been given the authority to cast out demons in Luke 10:19, and also in Mark chapter 16.  But many of the Christians have not been taught to do so.  

An authority on the subject was Dr. Lester Sumrall, of LESEA Broadcasting, who wrote on this subject.  One important book by Dr. Sumrall is "Demons, the Answer Book."  

Dr. Sumrall did a famous exorcism in the Philippines decades ago that was a national news item there from a woman bitten by demons.  The fang marks were visible in her arm.  The teeth marks were clearly not from human teeth.

Another expert on the subject is Rev. Kenneth E. Hagin whose books are available at Rhema.org

Hagin cured a woman of cancer by casting out a demon from her.  She was at the point of death, and was so weak, she had to be carried into the meeting in a bed.  After he cast out the demon, she lived decades longer.

Another authority on casting out of demons is Dr. Norvel Hayes of Cleveland, TN, (www.nhm.cc)

Winnie Roosendahl was proprietor of a motel in Washington State, and cast demons out of her husband.  She told of a Brother Willie who specialized in casting out demons of cigarette addiction from people.

Some people would say they don't believe in something they can't see.  But without seeing them, we believe in atoms, don't we?  If there were no atoms, how then do we have atom bombs?
