Methods of consumption

Cannabis is consumed in myriad ways, most of which either involve inhaling smoke from ignited plant or administering orally. Various devices exist for smoking, most common are implements such as bongs, chillums and smoking pipes, joints or blunts. Local methods differ by the preparation of the cannabis plant before use, the parts of the cannabis plant which are used, and the treatment of the smoke before inhalation.

Vaporizer heats herbal cannabis to 185–210 °C, which causes the active ingredients to evaporate into a gas without burning the plant material (the boiling point of THC is 200°C at 0.02 mm Hg pressure, and somewhat higher at standard atmospheric pressure), A lower proportion of toxic chemicals are released than by smoking, although this may vary depending on the design of the vaporizer and the temperature at which it is set.

An e-cigarette has a rechargeable battery and a heating element which vaporizes (in most brands) liquid nicotine from an insertable cartridge. If THC is loaded into the cartridge instead of nicotine, cannabis users may receive the benefits of a vaporizer at lower initial cost.
