Marijuana and other cannabis products are grown in the United States , Mexico , Canada , South America and Asia , and in other parts of the world. It can be cultivated outdoors and in indoor settings. Marijuana is usually smoked and the effects are felt within minutes. Depending on the dosage and other variables, users can feel relaxed, and have altered senses of smell, sight, taste and hearing, distorted senses of time, shifting sensory imagery, rapidly fluctuating emotions, fragmentary thoughts, impaired memory and dulling of attention.

In 1974, the average THC content of illicit marijuana was less than one percent. Today most commercial grade marijuana from Mexico/Columbia and domestic outdoor cultivated marijuana has an average THC content of about 4 to 6 percent., although some samples have tested as high as 25 percent THC.

High doses of marijuana can result in hallucinations. Marijuana smokers experience the same health problems as tobacco smokers such as bronchitis, emphysema, and bronchial asthma. Extended use is associated with anti-motivational syndrome, lung damage, and risk to reproductive systems.
