The main psychoactive part of cannabis is tetrahydrocannabinol ; one of 483 known compounds in the plant, including at least 65 other cannabinoids.
A cannabinoid is one of a class of diverse chemical compounds that acts on cannabinoid receptors in cells that represses neurotransmitter release in the brain.
Tetrahydrocannabinol, or more precisely its main isomer -trans-Δ9-tetrahydrocannabinol, is the principal psychoactive constituent of cannabis.

Cannabis can be used by smoking, vaporization, within food, or as an extract.
Cannabis smoking is the inhalation of smoke or vapors released by heating the flowers, leaves, or extracts of cannabis and releasing the main psychoactive chemical, Δ9-tetrahydrocannabinol, which is absorbed into the bloodstream via the lungs.
In physics a vapor or vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature.
Cannabis is often used for its mental and physical effects, such as a "high" or "stoned" feeling, a general change in perception, euphoria, and an increase in appetite.
The primary effects of cannabis are caused by the chemical compounds in the plant, including cannabinoids such as tetrahydrocannabinol, which is only one of about 400 different cannabinoids.

Short term side effects may include a decrease in short-term memory, dry mouth, impaired motor skills, red eyes, and feelings of paranoia or anxiety.
Consistent data in human and animal models aid in the understanding of underlying mechanisms and behavioural effects of cannabis on learning, memory and plasticity.
Xerostomia is dryness in the mouth, which may be associated with a change in the composition of saliva, or reduced salivary flow, or have no identifiable cause.
Long term side effects may include addiction, decreased mental ability in those who started as teenagers, and behavioral problems in children whose mothers used cannabis during pregnancy.
Tar is the common name for the resinous, partially combusted particulate matter produced by the burning of tobacco and other plant material in the act of smoking.

Onset of effects is within minutes when smoked and about 30 to 60 minutes when cooked and eaten.
They last for between two and six hours.
Cannabis is mostly used recreationally or as a medicinal drug.
Recreational drug use is the use of a psychoactive drug to alter one's mental state in a way that modifies emotions, perceptions, and feelings for recreational purposes.
It may also be used for religious or spiritual purposes.
Cannabis has been used in an entheogenic context - a chemical substance used in a religious, shamanic, or spiritual context - in India and Nepal since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE.
Traditionally, spirituality referred to a religious process of re-formation which "aims to recover the original shape of man," oriented at "the image of God" exemplified by the Torah, Christ, Buddha, Muhammad and others.
Religion is a cultural system of behaviors and practices, world views, sacred texts, holy places, ethics, and societal organisation that relate humanity to what an anthropologist has called "an order of existence".
In 2013, between 128 and 232 million people used cannabis.
In 2015, 43% of Americans had used cannabis which increased to 51% in 2016.
About 12% have used it in the past year, and 7.3% have used it in the past month.
This makes it the most commonly used illegal drug both in the world and the United States.
The earliest recorded uses date from the 3rd millennium BC.
Since the early 20th century, cannabis has been subject to legal restrictions.
The possession, use, and sale of cannabis is illegal in most countries of the world.

Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe.
Canada is a country in the northern half of North America.
Cannabis use started to become popular in the US in the 1970s.
