<snip> Except for the "puff of smoke" It wasnt an option given the whole gas mask thing.
I tend to disagree. It's like everything else with this addiction called photography. Timing, practice, patience, persistence, trail & error and lots and lots and lots of misses.
Set your self-timer on 20 seconds, with the head gear nearly in place so that you have enough room to take a puff, but don't inhale (the smoke will be thicker). Ten seconds out, begin letting out the smoke, but don't blow it out too quickly, 5 seconds out the timer will start beeping at you.... be ready and strike a pose..... Vouge.

The photo in that link...... probably +30 shots taken with the camera and about 6 shots of tequila.
