Alcohol ‘more damaging to brain health than marijuana’

The strongest point suggested that a new study from the University of Colorado Boulder has discovered alcohol could be way more injurious to your brain health than marijuana.

We have known the bad effects of alcohol, when it is consumed in high quantity. The study suggests that the most affected region is brain health as this may lead to proceed towards damaging. Smoking does not affect your brain health as much as unlike an alcohol can do.

The study of brain image results of adults who were aged between 18 to 55 years and teenagers between ages 14 to 18 concluded that variation occurred in results using alcohol and marijuana.

Grey matter in the tissue on the brain’s surface that primarily consists of nerve cell bodies. White matter is the deeper brain tissue that contains myelinated nerve fibers, which are branches protruding from nerve cells that transmit electrical impulses to other cells and tissues. The reduction in the size of white or grey matter or a loss in their integrity can lead to impairment in brain functioning. The researchers found that alcohol use, particularly in adults who had been drinking for many years, was associated with the reduction in grey matter volume of the brain as well as a reduction in the integrity of white matter in the brain. Moreover, the density of white matter was seen damaging in adult drinkers than in teenagers. While marijuana use has no impact on the structure of grey or white matter in either teenagers or adults. The effects of marijuana use were found to be much different, with no relationship found between smoking weed and a person’s brain structure. Here we have to clarify that we are not saying that marijuana does not have negative consequences, definitely, it has: but not like the negative consequences of alcohol. The study going back years in case of marijuana suggested that marijuana use is related to a reduction in the volume of the hippocampus and changes made in the cerebellum but there was no consistency in the study that how much these structures got reduced.

Factors may affect the health of using alcohol:

  • Alcohol itself is highly caloric
  • Higher risk of obesity or overweight
  • Depression and anxiety
  • Self-harm and suicide
  • Impair memory or incapable of forming memories.

Chronic drinkers display memory reduction as well as impaired emotional processes and social cognition — and these can persist even after years of abstinence.
