Marijuana – Is It Really a Dangerous Drug?

Drug

In 2012, a report at the University of California, San Francisco (UCSF) calculated that smoking one joint every single day for 20 years may be benign, though most participants only smoked two or three joints each month. “I was amazed we didn’t see impacts [of marijuana use],” reported UCSF epidemiologist Mark Pletcher, who led the analysis.

One assessment of varied epidemiological studies points to small sample size and poor study design as reasons for scientists’ inability to nail a connection between cannabis and cancer hazard. But some suspect that this kind of link does not exist, and then that marijuana could have even cancer-preventive outcomes. Even a 2008 study, as an example, indicated that smoking marijuana may lower the danger of tobacco-associated lung cancer, calculating that those who smoke both marijuana and tobacco have a much decrease risk of cancer than people who smoke just cigarette (though still a higher hazard than non smokers ).

But Pletcher isn’t sanguine about marijuana’s effects on the lungs, and supposes that there could continue to be long-term lung damage which could be tricky to find. “We really can’t guarantee ourselves about heavy use,” he explained.vaping cbd oil

There’s some evidence to suggest that stoned subjects exhibit increased risktaking and diminished decision making, and score worse on memory tasks-and remaining impairments have been detected days or weeks after use. Some studies also link years of frequent marijuana use to deficits in memory, learning, and concentration.

In this study, headed by researchers at Duke University,”that you could definitely see being a effect of cannabis use, IQ goes down,” said Derik Hermann, a clinical neuroscientist at the Central Institute of Mental Health in Germany that was not involved from the research.

But maybe not 4 months later, a re-analysis and computer simulation at the Ragnar Frisch Center for Economic Research in Oslo countered the Duke findings. Ole Rogeberg claimed that socio economic factors, not bud use, contributed to the reduced IQs found in cannabis users.

Rogeberg’s conclusion counters a sizeable literature, but which affirms a connection between marijuana use and neurophysiological decline. Studies in both humans and animals indicate that people who acquiring a marijuana habit in adolescence face long term negative impacts in brain function, together with several users finding it tough to concentrate and find new tasks.

Especially, most studies about them suggest that while there may be negative consequences of smoking as a teen, users who begin in adulthood are often unaffected. This could possibly be a result of endocannabinoid-directed reorganization of the brain during puberty, Hermann clarified. The intake of cannabinoids which includes marijuana use can result in irreversible”misleading of this neurological increase,” he said.

Along with the consequences of intellect, many studies suggest that smoking bud raises the probability of schizophrenia, and might have similar impacts on mental performance. Hermann’s group used MRI to find cannabis-associated neuron damage while in the pre-frontal cortex and found it was similar to brain changes found in schizophrenia patients. Other studies further suggest that weed-smoking schizophrenics have greater disease-associated brain changes and perform better on cognitive tests than their counterparts that are senile.

But a lot of the research can’t distinguish between brain fluctuations caused by marijuana use and symptoms related to the disease. It’s likely that cannabis-smoking schizophrenics”might have disagreeable symptoms [that precede full-blown schizophrenia] and so are self-medicating” with all the antipsychotic medication, said Roland Lamarine, also a professor of community health at California State University, Chico. “We’ve not seen a gain in schizophrenics, despite much more marijuana use.”

In actuality, other research shows cannabis-using schizophrenics score better on cognitive tests compared to non-using schizophrenics. Such conflicting reports might be caused by the varying concentrations-and varying effects-of cannabinoids in marijuana. In addition to tetrahydrocannabinol (THC), a neurotoxic cannabinoid that is responsible for bud’s anti inflammatory properties, the medication also includes a number of non psychoactive cannabinoids, including cannabidiol (CBD), which can protect against neuron harm. Hermann found that the volume of the hippocampus-a brain area essential for memory processing-is slightly smaller compared to cannabis users than in non-users, however more CBD-rich bud countered that result.

A deadly cocktail?

While data behind the harmful consequences of marijuana in its own are weak, some investigators are more worried about the medication in conjunction with other chemicals, such as smoking tobacco, alcohol, or alcoholism. Some studies indicate, by way of example, that marijuana might increase cravings for other medication, leading to its notorious label as a”gateway drug.” Research published earlier this month affirmed that this theory as it discovered, at least in rats, THC vulnerability increases tobacco’s addictive outcomes. What’s more, marijuana may not mix well with prescribed drugs, as cannabis induces the liver to metabolize drugs more slowly, increasing the chance of medication toxicity.
