Do you agree that they should be changed, as the law banning alcohol was changed?
Yes, I strongly agree the laws should be changed. I've reasons for my position.
Our present national policy was lunched as a "War on Drugs". I've never seen it as a war because our national leadership, over a span of thirty years has never fought it as a war. If they did, and being most of the "illegal" drugs originate from outside our nation, they would have issued ultimatums to the nations involved that flatly stated stop the flow or suffer a dire consequence. Voters of both political parties continue to elect people that represent them, and I'm convinced by their selections that the voters do not want a "War on Drugs".
Since our leaders, due to the voters, lack the necessary backbone to fight the "war", we need to change national policy to something they might have enough courage to enforce. The laws governing the distribution and sale of alcohol are a good indicator of what our leadership is willing to enforce.
