No. It cannot. Unfortunately, because we have placed virtually all moral authority in the hands of the State, the institutions which are most effective in preventing use of such things, namely Church and Family, are unable to do so.
People use illegal drugs in prison. Even the most severe penalties have not and will not dissuade people from manufacturing, distributing and using these drugs. It is rightly under the authority of the several states to decide policy on these drugs, but we cannot pretend that law enforcement will ever be a panacea for this problem.
The State makes a very poor church, indeed.
