I never said it was only a GUE thing. I just stated the facts as they relate to me and OP's question.On my OC trimix course in 1999 my instructor had smokers excluded from his courses. IANTD. It's not just a GUE thing and has been around a long time.
I don't want to get to deep into the smoking thing as it was one reason I posted, not the only reason but seems to be the one everyone is focusing on...so let me ask this..smoking is not allowed but that basically refers to only cigarettes right? I know GUE instructors that smoke cigars so how is that ok?
Or maybe we should look at alcohol. Moderate alcohol consumption is known to shrink areas of the brain associated with learning and development. It is also a depressant which slows down reaction times. Studies also suggest that you are at higher risk of injury if you are a regular drinker Maybe GUE should look to exclude anyone who consumes alcohol as well since physical fitness is so highly touted. Just a thought when considering safety.
I think it is perfectly acceptable to want to expand ones knowledge but not drink the Kool-Aid. As stated, I read all kinds of blogs and articles about diving, diving medicine and studies. I also regularly check out new gear that comes out so I can be as informed as possible for my own diving (mostly OC SM and Mod 2 CCR diving with Mod 3 coming this year) as well as for my students who are looking to me for advice. In order to do this, I go to TDI and read their blogs, I have taken the HFID micro-course and read any and all HFID posts and blogs that I can get my hands on. I scour the net for content.
I am guessing this thirst for knowledge is why many "lurk" or read about GUE as well as other organizations. I will never take a GUE course as I don't feel it is necessary for my development but I have nothing against those who decide to go that route. At the end of the day, it is about promoting diving in a safe manner and not about "my agency is better than yours"
