But your friend is right with her comparison to vaping/NRT in some ways. They can't bare that we get to enjoy our habit safely, so they have to make the harm reduced option as un-enjoyable as possible. It's a puritanical ideological thing. I imagine they use methadone orally, dispensed in little plastic cups from the chemist precisely because it removes the enjoyable parts from the equation. We can't have people enjoying their dirty habits after the habit has been made 'clean' by the 'professionals'.
