Negative Effects of Marijuana One of most active ingredients of marijuana is THC which can cause negative side effects that impact your body as well as the mind. It can slow down reflexes and impair decision-making. Like any other drug the side effects from marijuana vary from person to person. One person might feel stressed and disoriented while others might feel overfocused. In addition to your body, other factors such as type and amount of weed, your mood, your circumstances, environment/settings, your diet, and many others can influence you. Too much usage can have stronger effects such as hallucination while some people also experience increased anxiety and paranoia. Weed does impair mental functions such as memory, attention, and performance. This imparity can make driving or other actions hard to operate and in some cases impossible. However, for people who have heart and circulation disorders, low blood pressure, diabetes, or schizophrenia, weed can cause serious threats. No matter how weed enters your body, it impacts almost every major organ in your body in one way or another, though not always negatively. The biggest health issue of weed however is dependence. When THC reaches the brain, it’s supposed to impact certain brain cell receptors that contain chemicals similar to THC itself. These THC-like chemicals control brain development and other functions. As for short-term effects of weed on the brain, it over-activates the receptor cells and the person feels the high and gets into a relaxed mood. Depending on the quantity, quality and method of consumption, marijuana can produce a feeling of euphoria, or high, by stimulating brain cells to release the chemical dopamine. When smoked, the feeling of euphoria is almost immediate. When ingested in food, it takes much longer, even hours, for the drug to signal the brain to release the dopamine, which is the same chemical released in heroin and cocaine. This is why weed is considered a ” gateway drug” since it exposes a person to the high feeling. Once a person experiences a high multiple times their tolerance will increase causing them to turn to stronger drugs to achieve the high. When smoked, marijuana can increase your heart rate up to two times from the normal rate. The increased heartbeat rate is often linked to increased chances of heart attack, and that’s why doctors warn those with heart conditions to stay away from weed. THC in cannabis can have both short-term and long-term effects on the human brain. When THC is absorbed into the bloodstream, all the chemicals are carried to brain in addition to other organs. Heavy use can reduce thinking capabilities and can even cause memory loss for the short term. As for long-term effects, the overall brain development of heavy weed users is believed to be affected, especially if they started using weed in teenage years. A study suggested that teenage marijuana smokers lost on average eight IQ points between ages 13 and 38, and most of them never fully recovered even after quitting weed. Some other common physical effects of weed are short-term forgetfulness, depression, dizziness, increased appetite, and slowed down reflexes. Heavy users who have been using weed for long periods of time can experience withdrawal symptoms when they stop taking the drug. The impact can vary by person, how often they have used the drug, the strength of the drug and how often it has been since they have gotten high, among other factors. “In some cases, reported side effects of THC include elation, anxiety, tachycardia, short-term memory recall issues, sedation, relaxation, pain-relief and many more,” said A.J. Fabrizio, a marijuana chemistry expert at Terra Tech Corp, a California agricultural company focused on local farming and medical cannabis. Other effects include paranoia, hallucinations, trouble concentrating, and decreased coordination. When coming down from the high, users may feel depressed or extremely tired. While marijuana use causes a relaxed experience it can increase agitation, anxiety, insomnia and irritability.According to a 2014 Northwestern Medicine study of teen marijuana users, memory-related structures in the brain appeared to shrink, which could be possible signs of a decrease in neurons. These abnormalities remained two years after the teen stopped using marijuana, indicating that the drug has long-term effects and look similar to brains of schizophrenics. Most of marijuana’s side effects are the most dangerous during adolescence. One of the most common outcomes of smoking weed is a decline in school performance. Students who smoke marijuana may get lower grades and may more likely to dropout of high school than others who do not use. Increased risk of mental health issues are another very common consequence of Marijuana use and has been linked to a range of mental health problems in teens such as depression or anxiety. Psychosis has also been seen in teens at higher risk like those with a family history. Impaired driving. Driving while impaired by any substance, including marijuana, is dangerous. Marijuana negatively affects a number of skills required for safe driving, such as reaction time, coordination, and concentration. Potential for addiction. Research shows that about 1 in 6 teens who repeatedly use marijuana can become addicted, which means that they may make unsuccessful efforts to quit using marijuana or may give up important activities with friends and family in favor of using marijuana.For a lot of teens the biggest negative effects of using marijuana is laziness. Most teens will choose to prioritize smoking and getting high instead of doing their school work, spending time with their family, attending and putting effort into sports/ clubs, and even going to work high instead of sober. With putting marijuana as a priority teens are guaranteed for unsuccess. With this also comes the stigma tagged with marijuana. For a lot of teens they will choose to smoke and go out, if you do smoke and arrive to work wreaking you are guaranteed to be noticed. If your boss or coworkers have any reason to believe you smoke you will automatically be looked at as irresponsible, lazy, and immature. An employer does not want a stoner as an employee, there is more opportunity for mistakes on a high brain than a focus brain and you will be looked down upon and created a bad reputation for yourself.
