Re a diver with epilepsy (or any other medical condition) engaging in behaviors that are risky to self and risky to others, if you overheard others on a dive boat planning a non-nitrox dive that you knew posed great risk for decompression problems, would you assert a right to stop them from diving because you may be impacted if or when said divers encounter problems? Consider the newbie attempting a particulary difficult open water dive that you sense is beyond his/her capacity (e.g., nasty currents around rocky entrance/egress point) - again, do you assume the right and responsibility to get the person bounced from the dive? If, as some assert, smokers have higher pulmonary risks during diving, compared to non-smokers, do you have the right to require the smoker to "disclose" or to get the smoker bounced?
I do not claim a right to stop anyone from diving.
However, I do have a right to refrain from diving with someone who will increase my risk level beyond what I consider to be acceptable limits.
In addition, I would hate to see anyone get hurt.
Thus, in the first case, I might ask the divers how they planned to handle the deco obligation that they are going to incur if they execute their plan. If they had the situation under control, I would shut up. If they truly had no clue, I might consider mentioning this to the divemaster. However, I would not stop them.
In the second case, I would probably do what other people did for me when I was a newbie, i.e., strike up a conversation with the newbie, offer some guidance if asked and answer questions. If asked, or if it looks like the newbie is looking for an invitation, I might offer to buddy.
In the third example, it is not the smoking that is a problem. Rather, it is the symptoms that the diver presents. Thus, I would evaluate the diver the same way that I evaluate any other potential buddy.
My point about disclosure was not that we need to bring our entire medical chart and disclose personal details. In the case of Wingflyer152, however, the symptoms he might present are outside of normal dive rescue training and could, therefore, lead a rescuer to initiate an inappropriate course of action (bringing him to the surface instead of waiting for the seizure to end). Compare this to a smoker who's habit may place them at an increased risk for an event that dive rescuers are trained to handle.
