Mixing alcohol with other substances such as energy drinks is never really a good idea, and pairing it with energy drinks may become very dangerous, especially for the young adults whom drink it more often.
A teenage girl at the aged 16, died after consuming three cans of pulse, which is a mix of vodka, soda and guarana, at a party in Cheltenham. An autopsy was conducted and it was found that the cause of death could not be determined. At a certain point, alcohol stops making a person intoxicated and doing liver damage and starts to do SERIOUS cellular damage to all parts of the body. Your blood stops being efficient at oxygenating muscles and tissues, and the alcohol itself contribute to killing cells (especially brain-cells). At this point you can risk brain-damage, and even death. For this reason you might want to avoid the Caffeine. Alcoholic mixed drinks have many adverse effects and are a dangerous cocktail. The mixed drink needs something done about it.
When you ingest caffeine, it stimulates the body's fight or flight response, producing a surge of adrenaline. If our bodies are subjected to too much adrenaline, we can experience seizures, chest pain, heart palpitations and agitation – these are all signs of caffeine toxicity. The vast majority of these related to 'recreational' use of energy drinks, with affected 'recreational users' aged 15 to 21 years.
Energy drinks have become enmeshed in the subculture of partying. The practice of mixing energy drinks with alcohol which is more widespread than generally recognized has been linked consistently to drinking high volumes of alcohol per drinking session and subsequent serious alcohol-related consequences such as sexual assault and driving while intoxicated....Research has demonstrated that individuals who combine energy drinks with alcohol underestimate their true level of impairment.
Aside from the potentially harmful effects of the caffeine in energy drinks, experts are worried the trend to mix energy drinks with alcohol and recreational drugs could increase the risk of young people coming to harm. For example, it's thought the caffeine in energy drinks can mask some of the effects of alcohol – so you may feel less relaxed or less sleepy after drinking. This can lead to increased feelings of confidence, more risk taking, and an increased likelihood of drinking too much.
In a recent National Drug and Alcohol Research Centre (NDARC) survey, people said they believed energy drinks helped them party for a longer period of time. "It's one thing to drink [energy drinks] but when combining with others things they can cloud your judgment and make you do things you probably shouldn't," says Ms. Natasha Sindicich, coordinator of the ecstasy and related drugs reporting system at NDARC. It's also the 'shock, jolt, crash' effect that makes mixing energy drinks with other substances dangerous, Sindicich says.
The Australian and New Zealand Food Regulation Ministerial Council are currently considering the need for regulation of energy drinks. And so they should be.
However, the Australian Beverages Council – which represents drink makers – argues energy drinks in Australia are among the most regulated in the world. There are already warnings on the labels advising certain groups (children and pregnant women) against consuming the drinks, in addition to advice stating no more than two cans a day should be drunk, the council says.

Now that we have seen what causes acid rain, let's look at some of its effects on our forests.
Now that we have an idea of the dimensions of the problem of malaria in Africa, let's turn our attention to efforts now underway to control it.
Before going on to the next part which deals with I'd like to stress once again ... related cancers, I'd like to stress once again the fact that it is extremely difficult to pinpoint one specific cause for any cance
As a conclusion
To conclude then, we have seen the types of industries that produce the pollutants that cause acid rain - notably heavy industry or power plants dependent on sulfur-loaded coal. We also discussed the non-negligible role of domestic heating. The examples of eastern Canada or Sweden reminded us that the effects of acid rain are often felt miles from its source. By analyzing the mechanics involved, we realized that millions of acres of apparently healthy forests are already in the first stages of destruction. And the devastation of forests in Germany gave us a preview of what may lie ahead in many more areas if nothing is done.
