why is pot bad for your health
The immediate effects of taking marijuana include rapid heart beat, disorientation, lack of physical coordination, often followed by depression or sleepiness. Some users suffer panic attacks or anxiety. But the problem does not end there. According to scientific studies, the active ingredient in cannabis, THC, remains in the body for weeks or even months. Marijuana smoke contains 50% to 70% more cancer-causing substances than tobacco smoke. One major research study reported that a single cannabis joint could cause as much damage to the lungs as up to five regular cigarettes smoked one after another. Long-time joint smokers often suffer from bronchitis, an inflammation of the respiratory tract. The drug can affect more than your physical health. Studies in Australia in 2008 linked years of heavy marijuana use to brain abnormalities.
This is backed up by earlier research on the long-term effects of marijuana, which indicate changes in the brain similar to those caused by long-term abuse of other major drugs. And a number of studies have shown a connection between continued marijuana use and psychosis. Marijuana can change the structure of sperm cells, deforming them. Thus even small amounts of marijuana can cause temporary sterility in men. cycle. Studies show that the mental functions of people who have smoked a lot of marijuana tend to be diminished. The THC in cannabis disrupts nerve cells in the brain, affecting memory. Cannabis is one of the few drugs that causes abnormal cell division, which leads to severe hereditary defects. A pregnant woman who regularly smokes marijuana or hashish may give birth prematurely to an undersized, underweight baby.
Over the last 10 years many children of marijuana users have been born with reduced initiative and lessened abilities to concentrate and pursue
life goals. Studies also suggest that prenatal (before birth) use of the drug may result in birth defects, mental abnormalities and increased risk of leukemia (cancer of the bone marrow) in children. Marijuana smoke is also filled with many of the same chemicals as tobacco smoke, including ammonia, hydrogen cyanide, and formaldehyde. Some of these chemicals are known to cause cancer. Most users smoke pot in a joint or water pipe, so they breathe the smoke straight into their lungs. There's no proof that smoking marijuana causes lung cancer like cigarettes do.
But people who smoke pot do show signs of damage and precancerous changes in their lungs, especially if they also smoke cigarettes. PAnd a study published in 2013 in Cancer Causes Control found that heavy marijuana smoking might raise the risk of lung cancer. Pot smoking leads to other lung effects, too. "We know that patients see their doctor with more symptoms, including cough and wheezing, when they're marijuana smokers," Tetrault says. Could smoking marijuana change the way the brain works? That's what researchers are finding. Brain imaging scans of heavy marijuana smokers have revealed changes in blood flow to parts of the brain involved in memory and attention. Researchers have also noted differences in the size and shape of the thalamus, the part of the brain that's involved in consciousness and information processing.
Heavy pot smokers in studies score lower than non-users on tests of memory, attention, and learning. The more they smoked, the worse they did. The effects of smoking pot may be even more pronounced in teenage smokers than adults, because teens' brains are still developing. Regular users are more likely to be diagnosed with schizophrenia, especially when they have a family history of the condition. Marijuana can have effects beyond the lungs and brain. These include: Is It Addictive? People who stop smoking pot don't have the same withdrawal symptoms -- like anxiety and sweating -- they'd get if they were addicted to a drug like heroin. Yet those who use marijuana all the time can have a hard time stopping.
