You see this all the time. People that support abortion will use a 10 year old girl that was raped by an uncle and has some rare genetic disorder as their poster child in support of their cause: https://nypost.com/2017/07/24/10-year-old-victim-raped-by-uncle-fights-for-right-to-abortion/ These are not real arguments in that they are rare exceptions.
Pot, people put on masks and smoke it to the point of passing out, still inhaling even more with every breath after they are on the floor: https://www.facebook.com/Habitatsmokeshop/videos/every-wonder-what-its-like-to-hit-a-gas-mask-bong-stop-in-habitatsmoke-and-grab-/233192767241401/ (these girls don’t pass out, but people do it to that point). And do you know what happens? You wake up the next day very hungry. I won’t argue your point, there surely are some people that have a rare psychological condition or other health problem which may cause a bad outcome, but that is true for a roller-coaster or a water-slide too! https://www.youtube.com/watch?v=3Sv5my3-klk
