Marijuana Causes Less Brain Damage Than Alcohol, Study Finds
The common stereotype of the bamboozled stoner, left befuddled by a few too many funny fags, may not be as true as you think.
Indeed, a new study from the University of Colorado Boulder has discovered alcohol could be way more injurious to your noggin than a bit of spliffy clyro.
Indeed, it has now been suggested smoking weed may not even alter your brain structure long-term whatsoever, unlike the much more socially acceptable weekend bottle of wine.
This study – which has been published in scientific journal Addiction – investigated the relationship between using alcohol and marijuana and the volume of grey and white brain matter.
Any reduction in the volume of white or grey matter may impair brain functioning.
The study examined 853 people between the ages of 18 to 55 as well as 439 teenagers, all with ‘a range of alcohol and cannabis use’ and the results were rather surprising.
Grey matter volume was noted among both adults and teens who consumed alcohol, however the effects were found to be more pronounced among adults; particularly those who’d been drinking for a number of years.
The integrity of white matter was also damaged in adult drinkers, however this was not the case for teenage drinkers.
The effects of marijuana use were found to be much different; with no relationship found between smoking weed and a person’s brain structure.
Marijuana users in this instance were categorised as being those who’d smoked weed within the last 30 days.
Speaking with Medical News Today, co-author Kent Hutchison said:
While marijuana may also have some negative consequences, it definitely is nowhere near the negative consequences of alcohol.
However, Hutchison also noted how so far, investigations into the link between marijuana and brain functioning have produced mixed outcomes:
When you look at these studies going back years, you see one study will report marijuana use is related to a reduction in the volume of the hippocampus.
The next study then comes around and they say marijuana use is related to changes in the cerebellum.
The point is, there’s no consistency across all of these studies in terms of the actual brain structures.

Further research will be required to back up this study, as Hutchison points out, there’s still so much we don’t know about the effects of marijuana.
Indeed, according to the American Psychiatric Association, there are multiple negative effects for those who take marijuana – teens have higher school dropout rates, higher unemployment rates and decreased life satisfaction.
