What are your thoughts on this Columbia Professor who is very public and open about his drug use? : addiction

He’s obviously an advocate fighting to help drug addicts and change policies and stuff but maybe this isn’t the right way?
Idk what do you guys think? Like more power to you if you can use and then just stop but I don’t think he gets how this works for us, or how it helps us
