Marijuana – Is It Really a Dangerous Drug?

Quiet down!

In 2012, a study at the University or college of California, S . fransisco (UCSF) calculated that even smoking a single joint every day for 20 years might be benign, though most participants only smoked cigarettes a couple of joints each month. “I was surprised we didn’t see effects [of marijuana use], very well said UCSF epidemiologist Draw Pletcher, who led the study. cebede

One assessment of various epidemiological studies take into account small design size and poor review design as reasons for scientists’ inability to toenail down a link between cannabis and cancer risk. Sometimes suspect that such a link doesn’t can be found, and that marijuana could even have cancer-preventive effects. A 2008 study, for example, suggested that smoking cannabis may reduce the risk of tobacco-associated lung tumor, calculating that folks who smoke cigarettes both marijuana and cigarette have a lower probability of cancer than those who smoke only smoking cigarettes (though still a higher risk than non-smokers). 

Although even Pletcher isn’t sanguine about marijuana’s effects on the lungs, and suspected foods that there may be long-term lung damage which can be hard to detect. “We really can’t reassure yourself about heavy use, inches he explained.

Your brain on drugs

There is some evidence to suggest that stoned subjects demonstrate increased risk-taking and reduced decision-making, and score more serious on memory tasks-and extra impairments have been recognized days or even several weeks after use. Some studies also link many years of regular marijuana use to failures in memory, learning, and concentration. A recent and widely discussed report on the IQs of Fresh Zealanders followed since labor and birth found that cannabis users who’d started their behavior in adolescence had lower IQs than non-users.

In this study, led by researchers at Duke School, “you could evidently see as a consequence of cannabis use, IQ moves down, ” said Derik Hermann, a clinical neuroscientist at the Central Initiate of Mental Health in Germany who was not involved in the research.

But not 4 weeks later, a re-analysis and computer simulation at the Ragnar Frisch Center for Economic Research in Oslo countered the Duke studies. Ole Rogeberg contended that socioeconomic factors, not weed use, contributed to the bottom IQs seen in marijuana users.

Rogeberg’s conclusion desks a sizeable literature, however, which supports a website link between pot use and neurophysiological decline. Studies in both humans and pets suggest that folks who acquiring a marijuana habit in adolescence face long-term negative impacts on brain function, with some users finding it difficult to target and learn new jobs.

Notably, most studies on the subject claim that while there may be negative consequences of smoking as a teen, users who commence in adult life are generally unaffected. This kind of may be due to endocannabinoid-directed reorganization of the brain during puberty, Hermann explained. The consumption of cannabinoids that comes with pot use may cause irreversible “misleading of the neural growth, ” this individual said.

In addition to the consequences for intellect, many studies claim that smoking marijuana raises the chance of schizophrenia, and may have similar results on the brain. Hermann’s group used MRI to discover cannabis-associated neuron harm in the pre-frontal emballage and found that it was similar to brain changes seen in schizophrenia patients. Other studies further claim that weed-smoking schizophrenics have greater disease-associated brain changes and perform even worse on cognitive tests than their non-smoking counterparts.

Although much of this research can’t distinguish between brain changes resulting from pot use and symptoms associated with the disease. It can possible that cannabis-smoking schizophrenics “might have unpleasant symptoms [that precede full-on schizophrenia] and are self-medicating” with the psychotropic drug, said Roland Lamarine, a professor of community health at California Express University, Chico. “We have not seen an increase in schizophrenics, despite far more pot use. “
