This is not a valid point for the War on Drugs unless you also advocate treating alcohol and tobacco, which harm non-users just as much as any illegal drug.

Drug War related restrictions aimed at preventing prescription drug diversion have led to millions of individuals in severe intractable pain being severely undertreated, since doctors are afraid to prescribe adequate doses of opiates.

The curtailment of civil liberties does not make anyone healthier or more safe. Unfair police tactics currently used against drug dealers, traffickers, and users could be easily used against people of political, religious, or ethnic minorities.

Non-drug-abusing members of society are sometimes harmed by this decrease of civil liberties. Sometimes, homes and other property are seized without any charges so it is likely that people who weren't using, selling, or making illegal drugs have been hurt by the War on Drugs. reference
