My bet is he has developed some adult Asthma (I didnt get it till in my 40's), and found himself in some difficulty. Some guy or friend hands him an inhaler and he gets relief, sounds like this delivers astounding relief, far better than Symbicort or Ventoline and he continues to skate like before. He heads to camp as an outsider and doesnt want to alert the staff to any sort of problem (and being a new problem, as a kid, hopes it goes away, hell I was in denial of my problem for a long time) and resorts to the inhaler again, and gets popped. Yes stupid, but probably more naive and as we all know, we do pay for our mistakes big time. So his costly error hopefully becomes a screen that all other Leaf hopefull view and learn from.
And hopefully he has not screwed his career in the process.
