I'd never recommend it, although I completely understand it. I never sit down with a bowl without every intention to smoke the whole thing. However, I'm a father of a two year old with a very hectic job and sometimes an expected 90 min smoke turns into a whole lot less. I've hardly charred a pipe and had to set it down to revisit the next day on more than one occasion. If you know you're taking a 15 min smoke, my advice would be don't buy into the small "quick smoke" pipes. Personally I'd much rather load a full, half, or even 1/4 bowl in a full size pipe. Smoke what I can and save the rest for later. There's no reason you can't load a full bowl and smoke half now, half tomorrow. Or even load a half bowl and smoke 1/4 now and 1/4 later. The small bowl pipes always tend to burn too fast and hot for me, plus my mind tells me "I need to finish the whole thing right now". If I load a standard size bowl fully expecting not to smoke the whole thing in one sitting, I find that I can smoke slower and enjoy a lot better than a "one hit" pipe.
Just my opinion of course.
