Drug use has no single individual victim besides the drug user himself, but places the burden of caring for and dealing with addicts on the rest of society. Essentially, the entire society is the victim of drug use in the same way that insider trading, another victimless crime, negatively affects every trader in the market.

The victim of drug use is the drug user himself, who needs to be removed from the opportunity of taking drugs. A person who has no contact with drugs likely has a better life than a person who is given the opportunity to use drugs.

Drug use has harmful effects on third party individuals, such as babies born addicted to drugs, or traffic accidents caused by intoxication.

The War on Drugs is primarily aimed at drug dealers and not drug users. Drug dealers are victimizing potential customers.

Victimless crimes should be illegal if they are immoral. Drug use is immoral. Hence, drug use should be illegal.

I think Drug users should sign a disclaimer so that we can let them die in the street, without treatment so we don't have to shoulder the burden of paying for thier self imposed health care. We should also legalize drugs since as a society we can't stomach what a real war on drugs would entail. Either we really go to war against the drug trade or legalize so we can tax it.
