That is an interesting point! But in failed states (where de facto nothing is "illegal" as there is no rule of law), life is hardly peaceful. The source of the strife may be drugs in this case, but it's just because that's what pays well enough to approximate a lack of a strong state enforcing rule of law, even in a Western country like Mexico.
