[Alcohol and energy drink--can combined consumption of both beverages modify automobile driving fitness?].
Various fitness drinks under the designation of "energy or power drinks" or "brain or athletic food" are very popular among young people. For those entrusted with rendering expert opinions that poses the question of whether consumption of these beverages is of any importance when a person's ability to drive or mental capacity has to be assessed, especially in combination with alcoholic beverages imbibed at the same time. In the case discussed here-both the 20-year-old car driver and his passenger suffered not inconsiderable injuries-an alcohol concentration of 1.2 per mille was found at the time a blood sample was taken. Furthermore, a caffeine content of 1.5 micrograms/ml was noted. A value also reached after drinking a cup of filter coffee. In contrast, values of 2 to 10 micrograms/ml are reached when caffeine is used for therapeutic purposes. Values of more than 15 micrograms/ml are considered toxic. The measured caffeine content was thus fully insignificant. The same also applies to the "active ingredients" (taurine, glucuronolactone) contained in the beverage "Red Bull". Another assumption that, namely, the effect of alcohol can be offset by such beverages could lead to a situation in which young people incorrectly assess their ability to drive after imbibing alcohol and fitness drinks. That is naturally given support by corresponding tributes by the manufacturers ("improves performance", "invigorates the mind and body").
