I am suprised that there have been so few posts or safety articles written about drug and alcohol use in skydiving, especially in regards to instructors who abuse these substances. Please note I say "heavy" use. As a recent student, I am concerned with the quality of instruction and the clarity of judgement that is given from someone who has been partying until 3-4 in the morning and get up only a few hours later to teach AFF or do tandems. Alcohol and drug use seems to be acceptable and part of the "cool" skydiving lifestyle, although, people's lives are literally in their hands.
I don't believe any skydiver would fully trust their Reserve being packed by someone sh!tfaced or high - why accept lifesaving instructions from that same person? Again let me state, topping off a few brewskies is not a problem - even seeing the occasional joint I would not fret about - but, HEAVY use...at what point is too much?
Higher pay (should)=greater responsiblilty and self control. This is only my opinion, however, I believe this subject has been largely overlooked.
