Vaporizer (inhalation device)

A vaporizer or vaporiser is a device used to vaporize the active ingredients of plant material, commonly cannabis, tobacco, or other herbs or blends for the purpose of inhalation. However, they can be used with pure chemicals when mixed with plant material (e.g. tobacco-free nicotine).

Vaporizers contain various forms of extraction chambers including straight bore, venturi, or sequential venturi, and are made of materials such as metal or glass. The extracted vapor may be collected in an inflatable bag, or inhaled directly through a hose or pipe. With no combustion happening when used properly and cooler temperatures, a significantly better efficiency in extracting the ingredients can be obtained. Hence, the irritating and harmful effects of smoking are heavily reduced, as is secondhand smoke.

E-cigarette vaporizers

An electronic cigarette is a battery-powered vaporizer which simulates the feeling of smoking, but without burning tobacco. The three main types of e-cigarettes are cigalikes, eGos, and MODs. Their use is commonly called "vaping". The user activates the e-cigarette by taking a puff or pressing a button. They are often cylindrical, but come in many variations. Some look like traditional cigarettes. Most are reusable but there are also disposable versions called first generation cigalikes. There are also second, third, and fourth generation devices. Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor. E-cigarettes typically have a heating element that atomizes a liquid solution known as e-liquid. E-liquids usually contain propylene glycol, glycerin, water, nicotine, and flavorings. E-liquids are also sold without propylene glycol, without nicotine, or without flavors.

Cannabis

Cannabis (/ˈkænəbɪs/) is a type of flowering plants that includes three species (and seven taxa) or sub-species,sativa, indica, and ruderalis. The plant is indigenous to Central Asia and the Indian subcontinent.

Cannabis has long been used for hemp fibre, for hemp oils, for medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Many plants have been selectively bred to produce a maximum of THC (cannabinoids) which is obtained by curing the flowers. Various compounds of the plant, including hashish and hash oil, are extracted from the plant.

Globally, in 2013, 60,400 kilograms of cannabis were produced legally. In 2013 between 128 and 232 million people are thought to have used cannabis as a recreational drug (2.7% to 4.9% of the global population between the ages of 15 and 65).

Cannabis classification in the United Kingdom

Cannabis classification in the United Kingdom refers to the class of drugs, as determined by the Misuse of Drugs Act 1971, that cannabis is placed in. Between 1928 and 2004 and since 2009, it has been classified as a class B drug. From 2004 to 2009, it was in class C (less harmful).

Transfer to class C

As Home Secretary in Tony Blair's Labour government, David Blunkett announced in 2001 that cannabis would be transferred from class B of the Act to class C, removing the threat of arrest for possession. Arrest would still be possible for distribution, however. Reclassification had the support of a plurality of the public, with surveys at the time finding that 49% of British adults supported cannabis decriminalisation, 36% were against, and 15% were undecided. The transfer eventually happened in January 2004, after class C penalties for distribution had been stiffened. The Advisory Council on the Misuse of Drugs had recommended such a reclassification as early as 1979, a view endorsed by the Runciman Report in 1999.
