While human sacrifices may not be a literal ingredient of drugs, calling it victimless ignores a whole lot of problems caused by drugs. Buying pot from your friend who grows it is victimless. But fueling any black market, even one that avoids identity theft, means you are supporting the marketplace that provides service to drug traffickers of the sort that kill people or that delivers highly addictive drugs that ruin far more than just their user's own life. Yes, bad government laws have made these problems much worse and are preventing truly safe victimless market places that uses locally grown and produced drugs sold in moderation, but the black market is not victimless.
