Researchers Investigate Substance Dependency Through Genetic Models Using Fruit Flies
Let's Talk About Getting High with Fruit Flies
Sick of mice and rats in your science experiments? Not anymore! Researchers at the University of Utah have taken things to a whole new level by using fruit flies to study addiction, specifically cocaine addiction. That's right, these tiny creatures are giving us a leg up when it comes to understanding how people become hooked on drugs.
But here's the kicker: fruit flies don't even like cocaine. Cocaine is a plant toxin, and flies have sensors in their limbs that help them steer clear of bitter or toxic substances. Even when exposed to cocaine, they still wouldn't touch it with a ten-foot pole, until the scientists figured out how to shut off their ability to taste bitterness.
With their taste buds turning mute, the flies lost their aversion to cocaine and started chowing down on sugar water mixed with cocaine instead of regular sugar water. And they didn't need much time to develop a taste for it either, only 16 hours were enough to see a strong preference for the drug-laced drink. This means fruit flies could be the perfect lab rats to help researchers understand how addiction forms and which genes may be involved.
Fruit flies and humans might seem like an odd pair, but they have more in common than you'd think. Both share a large number of disease-related genes, and surprisingly, both react to cocaine in similar ways. Low doses make them more active, while high doses knock them out. Best of all, flies are easy to study, reproduce quickly, and are much cheaper to maintain than mice or rats.
Research on addiction has largely been focused on mice and rats, which takes more time and resources. However, with fruit flies as a new model, scientists can test far more genes in a much shorter time, potentially speeding up the discovery of possible treatments for cocaine use disorder, which affects around 1.5 million people in the U.S. alone.
By uncovering which genes are involved in addiction behaviors in fruit flies, researchers can look for similar patterns in mammals, including humans. This could lead to a deep understanding of the genetic basis of addiction and the development of more targeted treatments.
The study, supported by several national research institutes, shows how tiny fruit flies could help us take on one of the biggest public health problems today. From a simple question ("Why won't flies drink cocaine?"), we now have a whole new way of looking at addiction and getting closer to finding better treatments for those who need them the most.

In the realm of health-and-wellness, this new study on fruit flies could revolutionize mental-health treatments, particularly those addressing cocaine use disorder. The research, using fruit flies to understand addiction, might lead to the development of novel therapies-and-treatments involving CBD or other substances, as both fruit flies and humans react similarly to cocaine, opening new avenues for CBD-based interventions in mental health.
