But let's assume that Batts is talking about keeping Baltimore's addicts intoxicated for a year. If Baltimore has but 20,000 addicts (and not three times that many, as earlier estimates claimed), then the 175,000 units work out to less than nine doses for each of those 20,000 people. If they cop once per day, that's a little more than a week's supply. If it's three times a day, that would be a three-day supply. If there are three times as many addicts, then that's a one-day supply.
