This study showed that paraga is commonly consumed by commercial vehicle drivers operating out of the motor parks in Osogbo, southwest Nigeria. The lifetime use by 55.6% of the drivers is higher than the 51.6% recorded among secondary school students in Lagos [7]. This is worrisome because almost all the drivers (184 out of 188 drivers) who admitted to taking paraga in the past also admitted to driving shortly after consuming paraga in the past, in fact close to 75% of these respondents were doing it at least once a week. Paraga is basically an alcoholic drink masquerading as a medicinal preparation; it is therefore a major public health problem if a sizable proportion of commercial drivers consistently drive under its influence [7, 8].
Furthermore, paraga drinkers appear to be consistent in the usage of the drink: the percentage difference between lifetime and current use prevalence is less than 10%. This is similar to the findings of Oshodi et al. who also reported a less than 10% point difference between lifetime and current use among secondary school students in Lagos [7]. Similarly, Kadiri in a study of paraga use in a community in Lagos showed that 60% of paraga users were taking it on daily basis [16]. Looking at the reasons given by the drivers for taking paraga offers some explanations for this consistency in usage. For 55% of the drivers, the reason was to treat common cold and other illnesses. Thus, the respondents might continue to take the concoction as long as they felt they still had the illness for which paraga was being used. They might keep on taking it, even when they know it might be harmful; equating any harmful effects to the side effects of conventional drugs. This may explain the reason why 45% of those who felt that paraga was harmful also deemed paraga useful for treating illnesses. In addition, the relative high cost of orthodox medicine might have encouraged the use of alternative medicine among the populace [7]. The persistent use might also be because the drivers were getting addicted to some of the constituents of paraga; the most likely candidate being alcohol. Reasons such as “enjoyable taste”, “makes me to become more alert” and “makes me gain more energy” might be the manifestations of alcohol dependence [17].
It is also instructive that almost all the suggested benefits were for treating chronic illnesses like back pain or coping with emotional and stress related conditions. These are conditions that are very difficult to manage, for example, chronic back pain, which is an occupational disease of drivers, can be very difficult to treat satisfactorily and thus, patients may be encouraged to try different types of treatment [18].
Three quarters of current users were moderate to heavy users. Also, more than 50% of current users take paraga before driving, while driving, or at any time of the day, meaning that a sizable proportion of the drivers were at risk of driving under influence. This fact is buttressed by the admission by 25.6% of the drivers that they have been involved in road crashes when they drove after taking paraga. In addition, more than one-thirds of the drivers had seen someone become drunk on paraga.
We have shown that about 56. 3% of current users were either not willing to stop taking paraga, or they did not see any problem attached to paraga intake. How can these persons be persuaded to stop taking the concoction? Trying to address this question brings another one: Is there even a need for them to stop? Should the focus be on persuading them to avoid paraga if they want to drive?
We have established in paper one of this study, that paraga contains alcohol concentration that is similar to alcoholic drinks [11, 19]. It may therefore, be risky to drive after taking paraga, and on this evidence alone, drivers should be advised against driving after consuming alcohol. However, paraga also contains other ingredients such as herbs and minerals in concentrations that can fluctuate because the production is not controlled [7, 16, 19]. This can be dangerous because most medicines, including herbs are potentially dangerous when used inappropriately or in excess [20]. Furthermore, combining herbs or taking them without other herbs that are traditionally used to ameliorate their side effects can cause serious harms [21]. Traditionally in Africa, diseases are treated with herbs prescribed by traditional practitioners whose knowledge had been passed down through generations [6]. These medicine men had the required ethnobotanical knowledge to correctly combine the herbs. However, urbanization and modernization has broken down this process, and herbs are now commonly purveyed on the street. Paraga is one of the most popular forms in which herbal medicines are now dispensed on the street, and this popularity has come with a cost as there have been newspaper reports of deaths following consumption of paraga [22, 23]. The production and distribution of paraga needs to come under the scrutiny of the National Agency for Food and Drug Administration and Control (NAFDAC), which has the responsibility for controlling and regulating the manufacture, sale and packaging of food and drug in Nigeria. There is a vital need to study the photochemistry of the herbs used in formulating paraga, and to establish their efficacy. This will provide a scientific basis for establishing a policy on paraga use among the populace. In the meantime, drivers need to be educated on the potential of paraga to increase the risk for alcohol related traffic injuries and to reduce access to the concoction by restricting its sales in motor parks. Commercial drivers in Nigeria are members of the National Union of Road Transport Workers (NURTW) the Road Transport Employers Association of Nigeria (RTEAN) [24, 25]. These unions have a powerful hold on their members [8], and this has been capitalized-on by the authorities to successfully promote certain public health issues such as HIV/AIDS control and Accident Insurance among drivers [24, 25]. Such an approach can also be used to control paraga and other alcoholic drink consumption use by commercial drivers.
