I completely disagree with this baseless assertion. Not knowing something does not make you a "16 yr old", I ask questions like this all the time about a lot of stuff, including the very question the OP asked. OP asked a legitimate question, there is no need insult them. Most likely they are a new grower and curious what can be used and what can be tossed.
With that said @mikkel , to my knowledge everything but the roots and stems contains cannabinoids. Based on what I know there are only trace amounts in the fan leaves so it's very unlikely that you will experience a psychoactive effect from smoking them. The concentrations in the fan leaves would be affected by genetics and quality of grow. There is also personal tolerance but I would say technically you could get high from smoking them. I assume that most people would have to smoke so many leaves that you would get lightheaded or dizzy from just smoking long before you felt "high".
I personally would not smoke them.
