But it can look different depending on how it is prepared or packaged. What Does Marijuana Do? The membranes of certain nerve cells in the brain contain receptors that bind to THC, kicking off a series of cellular reactions that ultimately lead to the high people experience when they use marijuana. People use the drug because it elevates their mood and relaxes them. Depending on the level of THC, users may also experience euphoria, hallucinations, and paranoia.?? The most common way to use marijuana is to smoke it. It is often rolled into a cigarette joint, added to an emptied cigar casing to create a blunt, or smoked in a pipe or a water pipe bong. A newly popular method of use is smoking or eating different forms of THC-rich resins extracted from the marijuana plant.  It can also be baked into food (called edibles) such as brownies, cookies, or candy, or brewed as a tea. A Closer Look at Marijuana Use and Addiction What the Experts Say Marijuana use can be particularly problematic among teens because it may have a long-term impact on mental abilities including memory, learning, and thinking.

Because the most common method of use is smoking, marijuana use also poses respiratory risks and other smoking-related dangers. Smoking marijuana may increase the risk of wheezing, shortness of breath, and chronic coughing.?? According to a review published in 2015, research is mixed on whether or not smoking marijuana increases the risk of cancer. Some studies have suggested that there may be an increased risk, while others have found that marijuana use may actually have a protective effect.?? Despite these risks, there are reasons why people choose to continue to use marijuana. One study published in 2016 found people report using marijuana to:?? Relieve stress or tensionEscape lifes problemsEase boredomFeel good or euphoricFit in socially Why Do People Use Marijuana? Off-Label or Recently Approved Uses In addition to its use as a recreational drug, marijuana has a long history of use for medicinal purposes. While it has not been approved by the FDA, many states in the U.S. have legalized marijuana for at least some medical purposes. Medical marijuana is utilized to treat the symptoms of conditions rather than as a treatment for the condition itself. Research through 2017 suggests that marijuana is most effective in the treatment of muscles spasms, chronic pain, and nausea, making it helpful in relieving the symptoms of conditions such as multiple sclerosis (MS) and epilepsy.?? Some of the conditions that medical marijuana has been approved to treat in many states include: AIDSAlzheimers diseaseCancerCrohns diseaseEating disordersGlaucomaCachexiaMigrainesSeizuresSevere painSevere nauseaPersistent muscle spasmsWasting syndrome Further research on the potential benefits of medical marijuana is ongoing.

How to Know If Your Teen Is Smoking Pot Myths and Common Questions One common myth is that marijuana is a gateway drug that almost always leads to the use of harder drugs. While there is some evidence that exposure to marijuana may make it easier to use other substances, the National Institute on Drug Abuse (NIDA) suggests that most people who use marijuana do not go on to try to become addicted to other drugs.?? Another common myth is that marijuana itself is not addictive. While it is not common, repeated use can lead to both mental and physical dependence. The Centers for Disease Control reports that as many as 1 in 10 people who use marijuana will develop an addiction.?? Marijuana today often contains much higher THC levels than in the past, which increases its addictive properties. Tolerance, Dependence, and Withdrawal Research suggests that regular use of marijuana may lead to tolerance. When tolerance occurs, it takes increasingly larger doses or more frequent use to achieve the same effects. In a 2018 study, researchers found that regular use of marijuana led to less prominent effects when compared to non-regular use. The research also found that the physiological, behavioral, and cognitive effects of marijuana decrease over repeated exposure.?? How Long Does Marijuana Stay In Your System? The amount of time marijuana stays in your system may depend on the dose and frequency of use. Typically, marijuana may be detected in urine tests for up to 13 days after use, however, regular use may lead to longer detection windows. The type of test used can also influence detection windows. While marijuana is only detectable by blood for a few hours, it can be detected by hair follicle tests for up to 90 days. Addiction Research published in 2015 showed that over 30% of marijuana users in the United States had use disorder in 2012 and 2013.??  Long-term marijuana users are more susceptible to addiction. People who begin using marijuana before age 18 are four to seven times more likely than adults ages 22â€"26 to develop an addiction.?? Drug craving and withdrawal symptoms can make it hard for long-term marijuana smokers to stop using the drug. People trying to quit report irritability, sleeplessness, and anxiety. A drug is considered addictive if it causes someone to compulsively, and often uncontrollably, crave, seek, and use it, even in the face of negative health and social consequences. Marijuana meets this criterion. Can You Really Become Addicted to Marijuana? Withdrawal Some of the common symptoms of marijuana withdrawal that people report experiencing include:??
