An electronic vapor provision system includes a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system; a power supply for supplying power to the vaporizer to vaporize the liquid in response to a user activation of the device; and a control unit configured to estimate a user's expected activation duration and cause power to be supplied to the vaporizer for a period of time shorter than a user's activation duration.

A sun-powered smoking pipe with a lens suspended by two arms, whose arms hold the lens at a fixed distance from the pipe's bowl, the distance being equal to the focal length of the lens. The arms have equal lengths and swivel in tandem both at their attachment points to the lens and at their attachment points to the pipe so that the entire device can be folded flat quickly. The only calibration required by a user is to rotate the lens so that the focal point is aimed inside the bowl when the lens is held in the direction of the sun.

A smoking apparatus for positioning smoking material and for collecting ash residue from the smoking material. The smoking apparatus highlights its safety of use by smokers who may fall asleep while smoking, thus preventing house fires, damage to property and smoker burn injury. The smoking apparatus also protects against careless smokers from burning themselves or their clothes when they inadvertently drop whatever they are smoking.

Disclosed is a cartridge for a handheld smoking device with angled holes provided therein. The cartridge includes balls that rotate upon inhalation by a user. Orifices are provided in the cartridge that are angled in such a manner to cause air to flow in a particular direction and push the balls against the portion of the cartridge where product is likely to be located. The balls are therefore utilized more efficiently to distribute heat to the product and improve air flow within the handheld smoking device.
