Does your brain experience a weed impact long after the high wears off? What are the long-term effects of marijuana on the human brain? You are not the only one who is looking for answers to these questions. Scientists are also trying to conduct a thorough study on the long-term effects of marijuana, but the existing legal barriers interfere with detailed investigations of weed's effects on people. However, there are marijuana-related studies that have found some evidence of the way cannabis influences your brain long after you finish consuming it.
Tolerance is one of the mid-term effects of marijuana use. Under the constant influence of weed, the brain develops an ability to build up a tolerance to marijuana compounds.
When the brain reduces the number of cannabinoid receptors that interact with THC and other weed chemicals, consumers need to increase their dose to get the same high.
This reaction of the brain is similar to the effects of insulin and caffeine. When the brain cells meet too much THC, they reduce your sensitivity to it. However, results of scientific studies show that when consumers limit their weed use for a couple of days, the cannabinoid receptors becomes more sensitive to marijuana compounds again.
Meanwhile, some researchers have discovered that marijuana treatment can improve the mental condition of adult patients suffering from psychotic illnesses.
Investigating this issue, some scientists have come to the conclusion that people who are genetically predisposed to mental disorders are more likely to become chronic marijuana consumers.
There are some concerns that marijuana use in young age can potentially cause harm to the brain functions.
However, a 2016 study found no evidence of long-term mental impairment in identical twins who consumed cannabis.
Scientific studies on twins allow researchers to exclude genetic factors and consider only the influence of marijuana use. Thus, the lower mental performance of twins was not correlated with their weed consumption.
In contrast, a 2014 study discovered that the chronic use of marijuana by adolescents led to changes in the brain areas responsible for impulsivity and attention. However, those participants who first used weed when they were over 16 showed no reduction of their brain activity.
