I saw an episode of The Trinity Broadcast Network (a Christian television program) where they made a report about satanic cults performing rituals over crack cocaine before it was distributed into our communities.  It is a known fact that the drug takes possession of the individual. 
     We are fighting a spiritual warfare.  Our fight is against the ruler of this world, the great dragon that was cast out, that old serpent called the Devil.  He who deceive the whole world.   Like the fire Jinn (or Gin)...these spirits are a powerful and dangerous force against man.  Malevolent spirits have bedeviled humankind through out history and the only way to fight them is with the full armor of God...
     HOW TO SPOT A DEMON:
     Demons love to hide, pretend they don't exist.  They are around us and try to influence us in negative ways.  Demons tempt us with pleasure....things that we think make us "feel" good.  We are tempted through our eyes.  Demons hide behind loneliness, fear, pride, manipulation, chaos, lies, deceit, unforgiveness and religion.  People who are always troublemakers, negative, disagreeable, and chaotic are associated with demonic spiritual activities. 
     You and your loved one is not only fighting crack but fighting also demonic spirits that host the individual once the drug takes possession.  It is a battle for the mind/body/soul...it is a battle for the 'FREE WILL' of the individual.  The fruit of the (holy) spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.
     REHABILITATION IS ABOUT BEING DISCIPLINED:
     The mind of the individual who lacks self-control is more apt to follow the schemes of the unseen forces than those who meditate and seek higher levels of consciousness.  The mind can only be occupied with one force at a time.  When we allow dark forces to enter our being it affects us spiritually and causes harm on many different levels of our minds/body/soul.
     In order for rehabilitation to work there has to be a renewing of the mind...a change in thought.  The individual has to take control of his own "WILL" power and make the changes.  I offer solutions in the book "White Magic~Black Tragic"...the diary of a mad crackhead... that helped in my recovery.
