Drugs do not lead to crime. Desperation and opportunity, the need to survive, with a lack of morality, all directly lead to crime. Drugs do not make people commit crimes. Emotions, those mental states, do however. What we need, as a country, society, and human race is to recognize the importance of treatment of the mind above all else. Reduce suffering. Sure, there will always be a degree of sadness in life, we should as an intelligent species, strive to end mental and physical suffering.
