Chronic Adolescent Nicotine Use Leads to Increased Susceptibility to Alcohol Withdrawal in Adulthood

04.03.2010
If you smoked cigarettes when you were a teen, new research indicates you might be more susceptible to the negative effects of alcohol withdrawal later in life.

Baylor University researchers have found that the chronic exposure to nicotine during adolescence in animal models caused a nicotine-induced change in brain development that led to increased vulnerability to alcohol withdrawal in adulthood. It is the first study to look at the combined effect of nicotine and alcohol exposure during the adolescent developmental period on the severity of a subsequent withdrawal from alcohol in adulthood.

The results are documented in the journal Alcohol.

“This study provides evidence that the developing adolescent brain is susceptible to the actions of nicotine and that the effects of that early exposure can result in changes that can be seen in adulthood,” said Dr. Jim Diaz-Granados, associate professor and chair of the department of psychology and neuroscience at Baylor, who helped lead the study. “Perhaps the most interesting finding is the group that was exposed to nicotine and alcohol during adolescence did not show the same effect as the nicotine-only group. This suggests that there is an interaction between the actions of the two drugs during this developmental period.”

The Baylor researchers exposed animal models to nicotine while others were given saline. In addition, half were given alcohol and the other half were given saline, with the treatment lasting approximately one week. After six weeks, all were exposed to 64 hours of alcohol. Upon removal, the researchers measured the severity of alcohol withdrawal. Those exposed to nicotine only during adolescence showed the most severe withdrawal symptoms, while those exposed to nicotine and alcohol during adolescence did not. Diaz-Granados said one outcome of alcohol withdrawal is nervous system hyperexcitability and those that had been exposed to nicotine during adolescent development suffered more severe alcohol withdrawal-related hyperexcitability.

“The results are another important indication that drug use during adolescent brain development can have long-term consequences as compared to drug use during adulthood,” Diaz-Granados said.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
