The 4th part of the Narconon Rehabilitation Program is the Communication and Perception Course. Typically when using drugs, an individual can become very introverted, and will sometimes choose to not communicate any problems which are occuring with them. This can cause a drug addict to feel more shame and guilt about who they are, and the way they feel. This in-depth course of the Narconon program will initially focus on the students getting back into communication with others and the environment around them. This will be followed by special exercises to help the student to take attention off themselves, and putting more focus on their present time environment.
