Cannabis smoking
Cannabis smoking is the process of heating or igniting cannabis and inhaling the smoke which is produced. During this process the main psychoactive chemical in cannabis, ?9-tetrahydrocannabinol (THC), is absorbed into the bloodstream through the lungs. It is then transported to the brain where it binds to cannabinoid receptors. It has also been found that heating of cannabis results in the production of additional THC from the decarboxylation of the non-psychoactive ?9-tetrahydrocanabinoid acid (THCa).
Cannabis can be smoked in a variety of ways, some of which are more popular than others. The most common methods of smoking cannabis involve the use of implements such as bongs and smoking pipes, or rolling joints or blunts. These methods differ by: the preparation of the cannabis plant before use; the parts of the cannabis plant which is used; and the treatment of the smoke before inhalation. Cannabis smoke contains a range of harmful chemicals, including many which are also found in tobacco smoke. It has been shown that using a vaporizer results in less tar and carbon monoxide inhalation than smoking cannabis
Smoking Pipe
Smoking pipes, often called bowls or pieces, can be made of blown glass, wood, ceramic, stone, or a nonreactive metal (to avoid inhalation of undesirable metal vapors). When speaking about a specific pipe, the term “bowl” or “crater” often refers to the indentation where cannabis is placed in order to be smoked.
