Problem: Include this information with the above text: This study was significant because it was the first time data were collected on illicit drugs from several African countries at the same time, from diverse backgrounds using the same methodology (UNODC, 1999; Acuda et al., 2011). The results showed that the production, trafficking, and use of illicit drugs were common in all ten countries, with large amounts of drugs being seized (UNODC, 1999; Acuda et al., 2011). The study exposed how cannabis was commonly smoked, processed into paste, and incorporated into various foods and beverages (UNODC, 1999; Acuda et al., 2011). When cannabis was smoked, it was often mixed with other substances such as cocaine, crack cocaine, heroin, and methaqualone, and cannabis seeds were sometimes distilled into oil (UNODC, 1999; Acuda et al., 2011). Furthermore, in all ten countries, cannabis served as an additional source of income for families (UNODC, 1999; Acuda et al., 2011). The study also indicated that cocaine and heroin were used in all 10 countries, with the highest prevalence of use in South Africa (Acuda et al., 2011). In a separate study, Parry et al. (2005) analyzed data from 41 specialized alcohol and drug treatment centers in 2004 and found an increase in heroin use in South Africa over the previous five years, indicating the rise of heroin and cocaine usage from 1997 to 2004.
