Abstract
For decades, the consumption of caffeinated beverages intended to “energize” has increased
significantly. In Ghana, commercial drivers in major cities are rather at risk of daytime fatigue
because of the many trips these drivers make to earn more money due to lack of regulation on the
number of trips one makes in a day. Field observation shows that many commercial drivers rely
heavily on energy drinks, however not much on this has been investigated. To address this, a cross
sectional study was conducted on 210 commercial drivers across five taxi/bus stations in the
Kumasi Metropolis. A structured questionnaire was used to collect demographic data and other
information on the drivers’ pattern of energy drinks consumption. Five brands of energy drinks
were sampled and analysed for presence of psychoactive agents such as benzodiazepines, cocaine,
methamphetamine, opiates, tetrahydrocanobinoids and tramadol using the dip 6 test kit. HPLC was
used to detect and quantify caffeine in the energy drinks and Atomic Absorption
Spectrophotometer for detection of heavy metal contamination. The study showed the absence of
the psychoactive
agents’
benzodiazepines, cocaine, methamphetamine, opiates,
tetrahydrocanobinoids and tramadol in the energy drinks. However, varying amounts of caffeine
were detected in the energy drinks. The study also showed significant association between the
number of trips and the number of bottles of energy drinks consumed (r = 0.631. p-value < 0.05).
Hence, an increase in the number of bottles will cause an increase in the number of trips taken.
The R square value 0.398 (~0.4) shows a 40% probability that consumption of energy drinks makes
drivers make more trips. This result is desirable enough to lead drivers on to consume more energy
drinks, thereby making them only go on long hours of drive while reducing their efficiency (by
causing restlessness, insomnmia and confusion) as drivers on the road due to the cognitive changes
of the psychoactive substance. Heavy metal iron was detected in all of the energy drinks tested,
and copper in one of them, all below the allowed concentrations. In conclusion, this study showed
a high consumption of energy drinks among the drivers with no regard to safety on our roads.
