Abstract
A portable smoking booth includes an enclosure secured to a base that defines a smoking area. A smoke detector is positioned to detect smoke within the smoking area. An air purifying mechanism purifies air within the enclosure. A control mechanism for accepting payment from a user within the smoking area controls the smoke detector such that when payment is made, the smoke detector is disabled.
