Potentially, yes. But that case would only be good against poor _execution_ of the war on drugs, not the _concept_ that drugs need to be dealt with as if we were in a war. Activists seem to oppose the concept, which is where I disagree.
Not to mention the citizens who are victimized by the crime needed to sustain that addiction.
Legalization of marijuana has gone fine, but there are drugs so powerful that adults lose all control and reason, and I can’t see ever legalizing something like that.
You mean like alcohol?
