I have actually smoked banana skin once. About 15 years ago. I only had a few drags, don't know if it did anything though as even back then I had access to lots of weed.
try it, but i bet it's only for kids that haven't experienced smoking weed. If you have then I doubt smoking banana skin will affect you. Even in hospital and you need pain relief, if they know you smoke weed they'll bump up the morphine they give you.
