Alcohol ‘More Damaging To Brain Health Than Marijuana’
With marijuana legalization on the rise, an increasing number of studies are exploring the drug’s potential harms and benefits. However, a new study suggests that when it comes to brain health, alcohol is more damaging.
Researchers say that alcohol causes more damage to the brain than marijuana does.
Scientists at the University of Colorado Boulder conducted a review of existing imaging data that looked at the effects of alcohol and marijuana, or cannabis, on the brain.
Their findings linked alcohol consumption with long-term changes to the structure of white matter and gray matter in the brain.
The use of marijuana, however, seemed to have no significant long-term effects on brain structure.
Study leader Rachel Thayer, of the Department of Psychology and Neuroscience at the University of Colorado Boulder, and colleagues recently reported their results in the journal Addiction .
It is estimated that around 22.2 million people in the United States have used marijuana in the past month, making it “the most commonly used illicit drug” in the country.
Across the U.S., however, it is increasingly becoming legalized for both medicinal and recreational purposes. As a result of this changing legislation, researchers have been trying to find out more about how marijuana may benefit health, as well as the damage that it could cause.
Last year, for example, Medical News Today reported on a study linking marijuana use to a
greater risk of psychosis in teenagers, while another study claimed that the drug is ” worse than cigarettes ” for cardiovascular health.
On the other side of the coin, researchers have found that cannabinoids — which are the active compounds in marijuana — could help to prevent migraine , and a more recent study linked marijuana use to an increased sex drive .
Marijuana vs. alcohol: Which is worse?
For this latest study, Thayer and colleagues sought to learn more about how marijuana use affects the brain.
Study co-author Kent Hutchison, also of the Department of Psychology and Neuroscience, notes that to date, studies that have investigated this association have produced mixed results.
“When you look at these studies going back years,” he explains, “you see that one study will report that marijuana use is related to a reduction in the volume of the hippocampus. The next study then comes around, and they say that marijuana use is related to changes in the cerebellum […].”
“The point is that there’s no consistency across all of these studies in terms of the actual brain structures.”
With the aim of closing the gap on this inconsistency, the researchers conducted a new analysis on existing brain imaging data. They looked at how marijuana use affects white matter and gray matter in the brain, and how its effects compare with another “drug” that we have become so accustomed to: alcohol.
Gray matter is 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 team notes that any reduction in the size of white or gray matter or a loss in their integrity can lead to impairments in brain functioning.
“With alcohol, we’ve known it’s bad for the brain for decades,” notes Hutchison. “But for cannabis, we know so little.”
Marijuana use had no impact
The study included the brain images of 853 adults who were aged between 18 and 55 years and 439 teenagers between the ages of 14 and 18. All participants varied in their use of alcohol and marijuana.
The researchers found that alcohol use — particularly in adults who had been drinking for many years — was associated with a reduction in gray matter volume, as well as a reduction in the integrity of white matter.
Marijuana use, however, appeared to have no impact on the structure of gray or white matter in either teenagers or adults.
Based on these findings, the researchers believe that drinking alcohol is likely to be much more harmful to brain health than using marijuana.
[…] while marijuana may also have some negative consequences, it definitely is nowhere near the negative consequences of alcohol.”

When it comes to the possible benefits of marijuana use, however, Thayer and her team note that the jury is still out, and further research is needed to reach some conclusions.

NAFDAC warns against purchase of counterfeit anti-malaria drugs
The National Agency for Food and Drug Administration and Control (NAFDAC) has raised the alarm over the circulation of “counterfeit” Paludex tablets and suspensions in Nigeria.
The agency said the drugs, labelled as Paludex (Artemether/Lumefantrine), are manufactured by Impact Pharmaceutical Ltd, and Ecomed Pharma Ltd, Enugu and marketed by MD Life Sciences Ltd, Enugu.
The statement said laboratory tests conducted by a WHO-prequalified laboratory in Germany and NAFDAC revealed that the products contain zero percent active pharmaceutical ingredient (API), rendering them ineffective and potentially harmful.
NAFDAC warned that the products are not on its registered database and all NAFDAC registration numbers stated on the products are false.
“Genuine Artemether/Lumefantrine tablets or suspension is a combination of the two medications Artemether and Lumefantrine used to treat acute, uncomplicated malaria in adults and children,” the statement reads.
“The illegal marketing of medicines or counterfeit medicines poses a great risk to the health of people; by not complying with the regulatory provisions, the safety, quality, and efficacy of the products are not guaranteed.
“Also, poor-quality pediatric formulations or medicines in general have the potential of causing treatment failure when the API content is below the prescribed dose.
“All NAFDAC zonal directors and state coordinators have been directed to carry out surveillance and mop up the falsified products within their zones and states.
“NAFDAC implores distributors, healthcare providers, and patients to exercise caution and vigilance within the supply chain to avoid distribution, administration, and use of the products.
“All medical products must be obtained from authorized/licensed suppliers. The products’ authenticity and physical condition should be carefully checked.”

Less sugar in a child’s first 1000 days reduces risk of chronic disease, study says
A new study has found that reducing the amount of sugar children get in the womb and as toddlers can protect them against diabetes and high blood pressure in adulthood.
Published in the journal Science, the research reveals a critical period for healthy nutrition in the first 1,000 days of a baby’s life — from conception to age two.
The study found that cutting sugar intake in this window decreased the type 2 diabetes risk by about 35% and the risk of high blood pressure by roughly 20%. The researchers also discovered a delay in disease onset of four and two years, respectively.
The research team anaylsed data from before and after the end of the United Kingdom’s world war II-era sugar rationing in September 1953.
In January 1940, the UK government began food rationing to ensure fair shares for all during the wartime shortage.
Access to sugar, fats, bacon, meat and cheese was limited. When the rationing of sugar and sweets ended in September 1953, the average adult’s daily sugar consumption nearly doubled almost immediately, from about 40 grams to 80 grams.
Analysing the UK BioBank database of 60,000 people, the scientists compared health in middle age for 38,000 people conceived and born during rationing and 22,000 people conceived soon afterward.
The analysis showed a 30% reduction in the risk of obesity among sugar-rationed babies.
The study by the team at the University of Southern California also found that the risk of type 2 diabetes and high blood pressure increased with age. However, it increased faster in those conceived after sugar-rationing ended.
The results showed type 2 diabetes started on average four years later in adult life where there had been sugar-rationing during early childhood, and blood pressure two years later.
There was a 35% reduction in type 2 diabetes for those babies conceived during sugar rationing and a 20% reduction in high blood pressure.
“Sugar rationing created an interesting natural experiment,” said Tadeja Gracner, the study lead author and a senior economist at the Center for Economics and Social Research at the University of Southern California.
“We all want to improve our health and give our children the best start in life, and reducing added sugar early is a powerful step in that direction.
“With better information, environment and the right incentives, parents can more easily reduce sugar exposure, for kids and themselves.”
Also speaking, Keith Godfrey, a professor from the University of Southampton, said: “This is convincing new evidence, providing further support that reducing exposure of the unborn baby and newborn infant to sugar has lasting benefits that include lowering the risk of diabetes and high blood pressure in later adulthood.
“The findings are in keeping with our research showing lower rates of obesity in the children of mothers who eat low glycaemic index foods during pregnancy that are digested and absorbed more slowly, causing a slower rise in blood sugar levels.”
A previous study also suggested that high sugar intake during pregnancy may affect a child’s intelligence.

Five health benefits of aloe vera
Aloe Vera is a spiky succulent plant that grows naturally in dry, tropical climates like Africa, Asia, Europe, and southern and western parts of the United States. Over the years, this scrubby and pointy plant has been cultivated for its medicinal purposes.
Here are the health benefits you get from aloe vera as gel and juice.
- Aids digestion
Aloe vera, particularly aloe vera juice, has been proven to be a natural laxative.
The outer part of this plant contains a compound called anthraquinone glycosides which has laxative effects.
A study discovered that this compound can help relieve constipation while another research found that aloe vera could help reduce the symptoms of gastroesophageal reflux disease (GERD) — a digestive disorder that often results in heartburn — and irritable bowel syndrome.
However, when trying aloe juice for constipation for the first time, consume little amount of it.
- Reduces blood sugar levels
Both the gel and juice of aloe vera can help lower and control one’s blood sugar levels.
Several studies have indicated that taking aloe vera juice has some potential benefits for people with prediabetes and type 2 diabetes due to its effect on glycemic control.
- Rich in antioxidants
Aloe vera gel contains powerful antioxidants called polyphenols, which also have anti-inflammatory effects.
Antioxidants are important to health as they protect your body from damage caused by free radicals. These antioxidants have benefits ranging from reducing one’s risk of cardiovascular diseases to improving the immune system.
Aloe vera also has antibacterial and antiviral properties which is why it is used to treat and relieve burns and wounds.
- Promotes dental health
Due to its antibacterial properties, aloe vera juice and mouthwash improve various dental and oral conditions.
Aloe vera mouthwash is effective in reducing dental plaque. A study also showed that aloe vera mouthwash help reduces gum inflammation in people who had recently undergone tooth surgery to remove plaque.
- Skincare
Aloe vera is perhaps one of the most widely used herbal remedies for topical skin conditions. This is because the gel-like components of the plant are known to heal the skin from a variety of minor ailments.
This plant is also a natural moisturizer that helps soothes dry skin. Its anti-inflammatory properties also make it a potential treatment for skin conditions like burns, acne, and eczema.
Aloe vera also helps reduce the appearance of blemishes and wrinkles.
A 2009 study of 30 females over the age of 45 also prove that taking oral aloe vera gel increased collagen production and improved skin elasticity over 90 days.
