“...use marijuana socially with no ill effects, morally, financially, legally...”
What about the idea that willfully violating the law in this way leads people to believe that it is OK to ignore the law? What about the fact that the marijuana supply line is a violent lawless murdering entity which takes over more of America each year? You choose to ignore these ill effects? Or do you believe that they are OK?
That is a result of bad law. Examples: The byzantine and exploitative tax code (full of loopholes for favored special interests, thus transferring their share of the load onto everyone else) encourages tax cheating. The practice of using traffic enforcement for revenue rather than safety breeds contempt to speed limits even when they are set based on legitimate engineering criteria.
What about the fact that the marijuana supply line is a violent lawless murdering entity which takes over more of America each year?
That is a result of prohibition, as demonstrated by the before-and-after experiment with alcohol prohibition.
The Federal Government will no longer interfere with the laws of the individual states. There is no violation of the law.
