Marijuana – Is It Really a Dangerous Drug?

Sooth down!

In 2012, a study at the University or college of California, Bay area (UCSF) calculated that even smoking a single joint every day for 20 years might be benign, though most participants only used to smoke several joints each month. “I was surprised we didn’t see effects [of marijuana use], inch said UCSF epidemiologist Draw Pletcher, who led the study. cbd oil wholesale

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

Nevertheless even Pletcher isn’t sanguine about marijuana’s effects on the lungs, and suspected foods that there may nevertheless 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 show increased risk-taking and disadvantaged decision-making, and score more serious on memory tasks-and left over impairments have been recognized days or even several weeks after use. Some studies also link many years of regular marijuana use to cuts in memory, learning, and concentration. A recent and widely discussed report on the IQs of Fresh Zealanders followed since beginning 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 plainly see as a consequence of cannabis use, IQ should go 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 several weeks later, a re-analysis and computer simulation at the Ragnar Frisch Center for Economic Research in Oslo countered the Duke results. Ole Rogeberg contended that socioeconomic factors, not pot use, contributed to the bottom IQs seen in hashish users.

Rogeberg’s conclusion desks a sizeable literature, however, which supports a hyperlink 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 focus 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 cleverness, 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 destruction 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 more serious on cognitive tests than their non-smoking counterparts.

Although much of this research can’t distinguish between brain changes resulting from weed use and symptoms associated with the disease. Really 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 weed use. inch

In truth, other research suggests that cannabis-using schizophrenics score better on cognitive tests than non-using schizophrenics. Such contradictory reports may be because of to the varying concentrations-and varying effects-of cannabinoids in marijuana. In addition to tetrahydrocannabinol (THC), a neurotoxic cannabinoid that is in charge of marijuana’s mind-altering properties, the drug also contains various non-psychoactive cannabinoids, including cannabidiol (CBD), which can force away neuron damage. Hermann found that the volume of the hippocampus-a brain area essential for memory processing-is a little bit smaller in cannabis users within non-users, but more CBD-rich marijuana countered this effect.
