I'm always randomly thinking back to that off-brand DARE program I did in middle school where they told us one in ten people have a serious weed allergy and will just straight up drop dead if they ever smoke. They even made us go around the room, count off every ten people, then went "that's how many of you would be dead if everyone in this room smoked pot right now."
Like what cop thought that shit would be even remotely believable.
