It’s clearly time to rethink the U.S. War on Drugs. For many good reasons, consider this Editorial by the U.K.Guardian:

If the purpose of drug policy is to make toxic substances available to anyone who wants them in a flourishing market economy controlled by murderous criminal gangs, the current arrangements are working well. If, however, the goal is to reduce the amount of drugs being consumed and limit the harm associated with addiction, it is surely time to tear up the current policy. It has failed.

This is not a partial failure. For as long as courts and jails have been the tools for controlling drugs, their use has increased. Police are powerless to control the flow. One recent estimate calculated that around 1% of the total supply to the UK is intercepted.  Attempts to crack down have little impact, except perhaps in siphoning vulnerable young people into jails where they can mature into hardened villains.
