Energy drink warning

December 30th, 2009

There are no regulations regarding the amount of caffeine in energy drinks

“Energy drinks ‘need caffeine alert on cans’”, is the headline in the Daily Mail. The newspaper reports on a study that looked at 28 energy drinks and showed some have up to 14 times the caffeine content of a can of cola. Doctors have warned that these drinks should “carry health warnings”, so young people do not overdose on caffeine, says the newspaper.

The study is a review of the history and regulatory background of caffeine-based energy drinks in the US, including some of the “top selling US energy drinks”, which are also marketed in the UK. The authors discuss the potential for caffeine dependence and withdrawal problems that could be associated with energy drinks. This study did not measure the caffeine content of the drinks directly and did not investigate directly the effect of caffeine intake from these drinks on the body. The problems of toxicity and dependence that can follow caffeinated drink consumption, as discussed by the authors, will need further investigation before there is any proposed change in regulation.

Where did the story come from? Dr Chad J. Reissig and colleagues from the Department of Psychiatry and Behavioral Sciences at the John Hopkins University School of Medicine in Baltimore, US, carried out this research. The authors declare conflicts of interests in that they own stock in soft drinks companies. The study was supported by grants from the National Institute on Drug Abuse. It was published in the peer-reviewed medical journal: Drug and Alcohol Dependence. (more…)

Chronic Drinking Increases Stress Hormone

Cortisol, known as a “stress hormone,” plays an important role in the regulation of emotion, cognition, reward, immune functioning, and energy utilization. A study published in the September 2003 issue of Alcoholism: Clinical & Experimental Research has found that long-term chronic drinking produces an increase in cortisol both during intoxication and withdrawal.

“It has not been known whether the body adapts to the stress of drinking following daily heavy drinking in the non-laboratory setting, or whether cortisol levels continue to be elevated even after several weeks or months of drinking,” said Bryon H. Adinoff, Distinguished Professor in the department of psychiatry at the University of Texas Southwestern Medical Center at Dallas, medical director of the Substance Abuse Team at the Veterans Affairs North Texas Health Care System in Dallas, and first author of the study. “In this study, we show that even persons drinking for several months continue to show elevated levels of cortisol. In addition, levels of cortisol increase even further when the drinking stops. This increase occurs even before alcohol is gone from the body. The daily, heavy drinker may therefore have levels of cortisol two to three times the normal amount throughout the day and night.” (more…)

Athletes on performance enhancers more likely to abuse alcohol, other drugs

December 9th, 2009

College athletes who use performance-enhancing substances may be at heightened risk of misusing alcohol and using recreational drugs as well, according to new research in the Journal of Studies on Alcohol and Drugs.

The study, of 234 male athletes at one university, found that those who used performance enhancers — ranging from steroids to stimulants to weight-loss supplements — were more likely to admit to heavy drinking and using drugs like marijuana and cocaine.

Moreover, they also had elevated rates of alcohol- and drug-related problems, such as missing classes, failing tests or getting into fights.

The implication is that many athletes are not only experimenting with recreational drugs and alcohol, but suffering consequences as well, says study co-author Dr. Robert J. Pandina, director of the Center of Alcohol Studies at Rutgers University in Piscataway, New Jersey.

Until now, it had been unclear whether college athletes who use performance enhancers might have any higher risk of misusing other substances. On one hand, Pandina explained, many athletes might avoid habits that could threaten their performance on the field. On the other, athletes drawn to performance-enhancing substances might have certain traits — such as a propensity toward “sensation seeking” — that make the misuse of alcohol or other drugs more likely.

In their study, the researchers, led by Dr. Jennifer F. Buckman, assistant research professor at the Center of Alcohol Studies, found that nearly one third of the athletes acknowledged using a performance-enhancing substance in the past year. The list included banned substances like steroids, creatine, “Andro,” stimulants and weight-loss aids.

As a group, athletes who used performance-enhancing substances reported higher rates of drug and alcohol use. Seventy percent said they had used marijuana and one third admitted to cocaine use, versus 22 percent and 3 percent of athletes who did not use performance enhancers. They also had higher rates of smoking, binge drinking and prescription-drug misuse. (more…)

Pure Performance or Far From It

Artest admits drinking, blasts ref

ESPN.com news services

Ron Artest, the often-controversial Los Angeles Lakers forward, told a magazine interviewer he used to drink alcohol at halftime of NBA games.

I used to drink Hennessy … at halftime,” Artest says in the interview, which hits newsstands this week. “I [kept it] in my locker. I’d just walk to the liquor store and get it. – Ron Artest to The Sporting News

“I used to drink Hennessy … at halftime,” Artest said in an interview with the Sporting News, which is publishing the story in its Dec. 7 issue. “I [kept it] in my locker. I’d just walk to the liquor store and get it.”

Hennessy is a French cognac.

Artest said he drank when he played for the Chicago Bulls, where he played for his first three seasons (1999-2002). He has since played for Indiana, Sacramento, Houston and the Lakers.

A Lakers spokesman said the team had looked into Artest’s past before signing him, according to the Los Angeles Daily News.

“We do a thorough background check and due diligence prior to signing any player, and while we won’t share exactly what we did and didn’t know about Ron, we obviously felt comfortable or we wouldn’t have signed him,” team spokesman John Black said, according to the report.

NBA spokesman Tim Frank said Wednesday: “We have no comment and we hope Ron has a successful season.”

Bulls center Brad Miller, who played with Artest in Chicago and was traded with him to Indiana in February 2002, was asked if he thought Artest was telling the truth.

“Who knows with Ron,” Miller said. “You never knew what he was doing at that point.”

Artest was a member of the Pacers when he was involved in a fight in Detroit that spilled over into the stands. He was suspended for the rest of the 2004-05 season, which turned out to be 73 games. Artest told the Sporting News that the brawl “wasn’t my fault. … I don’t see anything I could have done different.” (more…)
