Really research your paper because "experts" will put in the picture you that 100% of all inhabitants who try it become addicted. That is not true -if a person tries it once or twice and decide not to do more they can. Its when a person keep on doing it that it becomes an addiction.
Your surrounded by the wrong place to ask that question. Turn around and be in motion back to Health.
