Drug. Facts: Marijuana National Institute on Drug Abuse (NIDA)What is marijuana? Marijuana refers to the dried leaves, flowers, stems, and seeds from the Cannabis sativa or Cannabis indica plant. The plant contains the mind- altering chemical THC and other similar compounds. Extracts can also be made from the cannabis plant (see "Marijuana Extracts"). Marijuana is the most commonly used illicit drug in the United States.

Its use is widespread among young people. In 2. 01. 5, more than 1. According to the Monitoring the Future survey, rates of marijuana use among middle and high school students have dropped or leveled off in the past few years after several years of increase. However, the number of young people who believe regular marijuana use is risky is decreasing. Reviews Conservative Dating Websites. Legalization of marijuana for medical use or adult recreational use in a growing number of states may affect these views. Read more about marijuana as medicine in our Drug. Facts: Marijuana as Medicine.

How do people use marijuana? People smoke marijuana in hand- rolled cigarettes (joints) or in pipes or water pipes (bongs).

They also smoke it in blunts—emptied cigars that have been partly or completely refilled with marijuana. To avoid inhaling smoke, some people are using vaporizers. These devices pull the active ingredients (including THC) from the marijuana and collect their vapor in a storage unit.

A person then inhales the vapor, not the smoke. Some vaporizers use a liquid marijuana extract. People can mix marijuana in food (edibles), such as brownies, cookies, or candy, or brew it as a tea. A newly popular method of use is smoking or eating different forms of THC- rich resins (see "Marijuana Extracts"). Marijuana Extracts. Smoking THC- rich resins extracted from the marijuana plant is on the rise. People call this practice dabbing.

These extracts come in various forms, such as. These extracts can deliver extremely large amounts of THC to the body, and their use has sent some people to the emergency room. Another danger is in preparing these extracts, which usually involves butane (lighter fluid). A number of people have caused fires and explosions and have been seriously burned from using butane to make extracts at home.

How does marijuana affect the brain? Marijuana has both short- and long- term effects on the brain. THC acts on numerous areas in the brain (in yellow). Image by NIDAShort- Term Effects.

When a person smokes marijuana, THC quickly passes from the lungs into the bloodstream. The blood carries the chemical to the brain and other organs throughout the body. The body absorbs THC more slowly when the person eats or drinks it. In that case, they generally feel the effects after 3. THC acts on specific brain cell receptors that ordinarily react to natural THC- like chemicals.

These natural chemicals play a role in normal brain development and function. Marijuana overactivates parts of the brain that contain the highest number of these receptors. This causes the "high" that people feel. Other effects include: altered senses (for example, seeing brighter colors)altered sense of timechanges in moodimpaired body movementdifficulty with thinking and problem- solvingimpaired memoryhallucinations (when taken in high doses)delusions (when taken in high doses)psychosis (when taken in high doses)Long- Term Effects. Marijuana also affects brain development. When people begin using marijuana as teenagers, the drug may impair thinking, memory, and learning functions and affect how the brain builds connections between the areas necessary for these functions. Researchers are still studying how long marijuana's effects last and whether some changes may be permanent.

For example, a study from New Zealand conducted in part by researchers at Duke University showed that people who started smoking marijuana heavily in their teens and had an ongoing marijuana use disorder lost an average of 8 IQ points between ages 1. The lost mental abilities didn't fully return in those who quit marijuana as adults. Those who started smoking marijuana as adults didn't show notable IQ declines. In another recent study on twins, those who used marijuana showed a significant decline in general knowledge and in verbal ability (equivalent to 4 IQ points) between the preteen years and early adulthood, but no predictable difference was found between twins when one used marijuana and the other didn't. This suggests that the IQ decline in marijuana users may be caused by something other than marijuana, such as shared familial factors (e. NIDA’s Adolescent Brain Cognitive Development (ABCD) study, a major longitudinal study, is tracking a large sample of young Americans from late childhood to early adulthood to help clarify how and to what extent marijuana and other substances, alone and in combination, affect adolescent brain development.
