and Cannabis of Behavioral Effects Physiological
Users can experience anything from a pleasant euphoria to panic. Other psychological effects of marijuana include:. The variability of the effects of marijuana is due in large part to dosages. Low doses have mild effects while feelings of panic usually happen with very high doses. Extremely high doses have also been associated with hallucinations, delusions, and dysphoria.
Despite the long standing prevalence of marijuana use, there is a lack of data when it comes to the long term psychological effects of marijuana. Research has shown that heavy and frequent use of marijuana can lead to lower IQ and cognitive function. THC affects the brain by activating the cannabinoid receptor type 1 CB1 , which has an effect on memory , cognition, and pain.
According to a study published by the National Institute of Health, heavy and prolonged use of cannabis can have long-term effects on the executive functions of the brain. The functions, like decision making, reasoning, memory, and problem-solving, can take a month or more of abstinence to recover.
This phenomenon often leads to weight gain among users, but it has peaked the interest of doctors and scientists.
One Johns Hopkins University study in highlighted these appetite-increasing effects. Subjects that smoked marijuana increased their daily caloric intake by 40 percent. This effect has some potential uses in the medical field and has been studied as a way to treat anorexia. The appetite stimulating effects of cannabis have been used to combat anorexia and give patients a healthy appetite.
Doctors have also begun using marijuana to treat multiple sclerosis MS , epilepsy, and other neurological movement disorders. A review looked at medical marijuana use across different cases and found that it was effective for curbing spasticity, spasms, urinary problems, and other symptoms. However, researchers warn doctors to weigh risks carefully, specifically pointing at the possible risk of adverse psychological effects.
However, studies show that there is some relationship between marijuana use and subsequent hard drug use, but the nature of that relationship is still unknown. It could be that once people engage in illicit drug purchasing, they are more likely to be offered or have channels to obtain hard drugs. It could be that personality types that are more likely to try and buy cannabis are also more likely to try harder drugs.
More research is needed to determine whether social factors, individual personality characteristics, or the effects of the drug are the reason this occurs.
While there is little evidence to suggest that there is a significant risk of becoming chemically dependent on cannabis, there is a risk for psychological addiction.
Marijuana is the most commonly used illegal drug in the United States, with Click on the sections below to learn more about how marijuana use can affect your health. About 1 in 10 marijuana users will become addicted. For people who begin using before the age of 18, that number rises to 1 in 6. People who are addicted to marijuana may also be at a higher risk of other negative consequences of using the drug, such as problems with attention, memory, and learning.
Some people who are addicted need to smoke more and more marijuana to get the same high. It is also important to be aware that the amount of tetrahydrocannabinol THC in marijuana i. The higher the THC content, the stronger the effects on the brain. In addition, some methods of using marijuana e.
Marijuana use directly affects the brain — specifically the parts of the brain responsible for memory, learning, attention, decision making, coordination, emotions, and reaction time. Heavy users of marijuana can have short-term problems with attention, memory, and learning, which can affect relationships and mood. Marijuana also affects brain development.
When marijuana users begin using as teenagers, the drug may reduce attention, memory, and learning functions and affect how the brain builds connections between the areas necessary for these functions. This means that someone who uses marijuana may not do as well in school and may have trouble remembering things. The impact depends on many factors and is different for each person. It also depends on the amount of tetrahydrocannabinol THC in marijuana i.
Developing brains, like those in babies, children, and teenagers are especially susceptible to the hurtful effects of marijuana. Although scientists are still learning about these effects of marijuana on the developing brain, studies show that marijuana use by mothers during pregnancy may be linked to problems with attention, memory, problem-solving skills, and behavior problems in their children.
Marijuana and cannabinoids the active chemicals in marijuana that cause drug-like effects throughout the body, including the central nervous system and the immune system.
The main active cannabinoid in marijuana is deltaTHC. Although marijuana and cannabinoids have been studied with respect to managing side effects of cancer and cancer therapies, there are no ongoing clinical trials of marijuana or cannabinoids in treating cancer in people.
Relying on marijuana alone as treatment or for managing side effects while avoiding or delaying conventional medical care for cancer may have serious health consequences. Studies of man-made forms of the chemicals found in the marijuana plant can be helpful in treating nausea and vomiting from cancer chemotherapy.
At this time, there is not enough evidence to recommend that patients inhale or ingest marijuana as a treatment for cancer-related symptoms or side effects of cancer therapy.
Smoked marijuana delivers THC and other cannabinoids to the body, but it also delivers harmful substances to users and those close by, including many of the same substances found in tobacco smoke, which are harmful to the lungs and cardiovascular system.
Researchers have found limited evidence of an association between current, frequent, or chronic marijuana smoking and testicular cancer non-seminoma-type. More research is needed to understand the full impact of marijuana use on cancer. Even though pain management is one of the most common reasons people use medical marijuana in the U. A few studies have found that marijuana can be helpful in treating neuropathic pain pain caused by damaged nerves. Using marijuana makes the heart beat faster.
More research is needed to understand the full impact of marijuana use on the circulatory system to determine if marijuana use leads to higher risk of death from these causes. In many cases, marijuana is smoked in the form hand-rolled cigarettes joints , in pipes or water pipes bongs , in bowls, or in blunts—emptied cigars that have been partly or completely refilled with marijuana. Smoked marijuana, in any form, can harm lung tissues and cause scarring and damage to small blood vessels.
The known health risks of secondhand exposure to cigarette smoke—to the heart or lungs, for instance—raise questions about whether secondhand exposure to marijuana smoke poses similar health risks. While there is very little data on the health consequences of breathing secondhand marijuana smoke, there is concern that it could cause harmful health effects, including among children. Recent studies have found strong associations between those who said there was someone in the home who used marijuana or a caretaker who used marijuana and the child having detectable levels of THC — the psychoactive ingredient in marijuana.
Marijuana use, especially frequent daily or near daily use and use in high doses, can cause disorientation, and sometimes cause unpleasant thoughts or feelings of anxiety and paranoia. Marijuana use has also been linked to depression and anxiety, and suicide among teens. Regular pot smokers are more likely to have persistent coughs, have some trouble breathing, and produce excess phlegm and mucus from their throats.
Out of the respiratory system, THC the active compound in cannabis exits the lungs and enters the bloodstream, where it moves throughout the body. The National Institute on Drug Abuse cautions that the chemical can increase the heart rate by as many as 50 beats per minute, which can last as long as three hours. Smokers who have heart disease could be at a greater risk of heart attack.
Research from the Journal of the American Heart Association suggests that regular marijuana use can not only contribute to the possibility of a heart attack, but also to heart rhythm disorders and stroke , even in young people who have no other risk factors for heart disease. The point is echoed by the American College of Cardiology , which notes that marijuana causes irregular heart rates and increases the risk of an acute coronary syndrome, which refers to any number of conditions that can be brought on by the sudden interruption of the blood flow to the heart.
As a result of this, users who are susceptible to conditions of the heart are taking a serious risk when they smoke marijuana. One of the more distressing risks of long-term effects of marijuana consumption is found in women who are pregnant. Marijuana has a complicated relationship with sexual libido and function. However, animal studies have found that marijuana inhibits the receptors in the erectile tissue of the animal penis, according to a study in the Journal of Sexual Medicine , suggesting that cannabis consumption before sex does more to limit sexual function than it does to help it.
Even as some research has suggested that long-term marijuana use carries a minimal risk of physical consequences, such as that published in JAMA , scientists still urge caution. The sentiment is shared by some smokers themselves. Writing in Vice magazine, one user noted that most of the heavy smokers he knows get high on a regular basis without the stereotypical feelings of laziness or paranoia.
Some went so far as to note that long-term weed use even changed their personalities, making them less outgoing and socially engaged. One negative effect the JAMA scientists noticed was that people who smoked pot for a long time tended to have worse periodontal gum health than others, which in some cases led to the development of gum disease. Aside from effects on the brain and body, what else can the long-term consumption of marijuana do?
