UT students investigate effects of co-abusing meth and alcohol – the blade

UT students investigate effects of co-abusing meth and alcoholHave you ever seen “before and after” photos of meth users? If so, you know how much using the drug can change the human body.

People addicted to methamphetamine often have sunken cheeks and visible weight loss, as well as sores and scabs on their faces from picking at their skin. But have you thought about how the drug affects the inside of their body?


Meth is classified as a psychostimulant, which means that it acts as an antidepressant or mood-elevator. This drug gives you a sudden burst of intense happiness, increased self-confidence and energy, while increasing your heart rate and body movements.

Alcohol also can affect your behavior and your brain, but unlike meth, it is classified as a depressant. Consuming large amounts of alcohol slows down your brain function, which can result in slurred speech, lack of motor coordination, or blackouts.

A recent study found that within the United States alone, about 1.2 million people reported using meth in the last year but importantly, 77 percent of meth abusers also binge drink alcohol. In fact, consuming alcohol first can increase the risk of using meth more than fourfold. This is considered “co-abuse” when two drugs are used at the same time.

The goal of our research at the University of Toledo is to determine what happens to the brain after the co-abuse of alcohol and meth, and identify the mechanisms responsible for those effects.

The co-abuse of alcohol and meth can add to effects common to both drugs, such as increases in heart rate and blood pressure.

Therefore this combination can increase your risk of heart disease and stroke, as well as behavioral changes such as paranoia, hallucinations, and aggression.

Our lab looked specifically at the effect on the brain, and we discovered that in combination alcohol and meth damage two specific types of brain cells — dopamine and serotonin neurons — within a brain region known as the striatum.

Damage to these cells in this part of the brain can lead to multiple problems, such as movement disorders, clinical depression, and an overall decrease in brain function.

Co-abuse of alcohol and meth destroys more of these brain cells compared to groups exposed to either alcohol or meth alone.

However, an additional, more ominous picture emerges when the drugs are used in combination.

We found that their combined use results in a new type of brain damage that is different from when either drug is abused on its own, or simply the combined effects of one drug added to the other. This would be like saying, 2+2 does not equal 4, but rather it equals 7.

Something different, and far more dangerous, is occurring.

We have observed that in instances of co-abuse these inflammatory molecules are triggered to enter the brain, contributing to brain damage after the combined use of alcohol and meth.

To test how large the role of inflammation is in contributing to brain damage, we measured the counter-effects of a drug similar to ibuprofen. We confirmed that not only was inflammation blocked under that circumstance, but brain damage also was lessened after co-abuse of alcohol and meth.

The results of our experiments are significant because this is the first report of enhanced brain damage after co-abuse of alcohol and meth compared to either drug alone.

Additionally, we have identified a role for an inflammation response outside of the brain that may contribute to increased brain damage after co-substance abuse. This will potentially identify new targets for therapy to help people addicted to alcohol and meth individually, as well as those who co-abuse more than one drug.  Chairman, Tyler Cornell squirmed, “How and Why?  Do you see the before and after pictures?  It is supposed to be the opposite for infomercials and that is a tough business.  This is what people want?  This is what people are buying?  I’ve got to hear that sales pitch. I think family and friends should start helping each other instead of avoiding this epidemic before their loved one’s self medicate into this stage of addiction.

Amanda Blaker did a great job with this article.  It is an in depth analysis with research provided.  Research that describes the repercussions of the chemical combination of certain drugs together.  One of those drugs is called alcohol which is  perfectly legal for those over 21. Per client stories, “Alcohol doesn’t come into the mix because it is legal.”

Now, many states are considering legalizing THC into the mix of legal chemicals which is another gateway to mixed abuse.  With consideration to the political season of nominee’s, how many people do politicians have to sacrifice for more tax revenue when you read a story like Amanda Blaker researched?  I’d like to see a debate on something real.”
