it is inhaled when you smoke and breathe it in, as tobacco is, and once you breathe it in it enters the lungs and then enters the blood flow through the alveolar, where the exchange of oxygen and carbon dioxide takes place and the blood is oxygenated. With the THC in your blood system (chemical responsible for the effects of marijuana), it is transported to your brain eventually and the chemicals from marijuana now in your blood system trigger the release of endorphins and cannabis, the two chemicals responsible for the emotion of happiness. This is why marijuana causes one to temporarily feel uncontrollably happy (high). When marijuana is often used, however, one becomes accustomed to the happy sensation and this sensation becomes normal, meaning that more morphine and cannabis chemicals must be released by the brain to feel happier. This makes the user want to use marijuana for longer time periods or more often, as well as make the user desire a stronger marijuana (stronger marijuana means a higher concentration of THC - the chemical that triggers happiness remember!) in order to feel different from normal. This is what leads to dependency and addiction.

Marijuana can also be eaten (either cooked into food or raw). Less commonly it can be made into a tea or chewed to achieve the same effect. In California USA, medicinal
marijuana derivatives can be procured legally in pills, oral liquids and topical sprays.
