Drug use, including alcohol and tobacco, by teens is a natural part of growing up. Individuals are thirsting for a means of identifying self. Evolution mandates this search not simply for the sake of being able to say "I am this or that", but to maintain the discovery process inherent in youth. Discovery (learning) is intrinsically a growth process and as such is required for the health of all individuals. Discovery increases the negative entropy of an person. The current level of man's average psychological development, as reflected in our society, does not yet provide the path for becoming a "thermodynamically sound" adult. a path of ongoing self development and growth. Whether one continues to use potentially beneficial drugs (psychedelics) in a socially and personally beneficial way, is up to the individual."Just say no" must be replaced by "Just say Know".
