Sort of, but I'm thinking more along the lines of the fog machine itself serving as the passthru! Though I don't know enough about the internals of the FM to decide whether or not it's a safe or sanitary system for actually consuming the vapor it emits, but I think the technology there could be retrofitted with human consumption in mind! I know the hardware already exists to regulate the temperature of the heating elements in herbal vaporizers (in 1º increments, ranging from around 200-500º, and with either analog or digital regulation and metering depending on what unit you're looking at), and I know there are relatively simple means of a adjusting the speed of the fan in the pump, so then you'd pair those two features with the reservoir and feeding technology in the fog machine (but obviously they'd have to be retrofitted with safer materials, ie silica wick or even ss mesh and a food-grade pyrex, ss, or polycarb reservoir) and a piece of surgical tube with an air inlet to let you draw on it without creating any actual suction with the feeding/heating system and you'd have one HELL of a device! Size wise, I bet you could get it down to a 4x6x3" box with an extension cord for power and a hose for actually using it.
Absolutely not.
