Whoonga is a relatively new addition into the drug market. The need for this study was prompted by the devastating effects this new arrival has had in the lives of young people addicted to it. The purpose of this study was to investigate the effects of whoonga on the learning of affected youth in Kwa-Dabeka Township. This study adopted a qualitative method and employed a phenomenological approach to explore the experiences of participants with regard to whoonga use and their learning. Data was collected through purposive sampling. Interviews were conducted, using semi-structured and unstructured questions with the help of an interview guide. Observations were also conducted to collect more data. This was done in the classroom during teaching and learning, as well as outside the classroom during recess. The study employed a social learning theoretical framework on the experiences of participants with regard to the use of whoonga. Four participants from one high school in Kwa-Dabeka Township were involved in the study. Themes that emerged from the study were that all the participants were totally ignorant of what they were getting themselves into before they started using whoonga. Peer pressure, coupled with curiosity made their decision to use whoonga easy. Challenges that participants face now on daily basis are far beyond their young age. The findings have indicated that learning is a situation of near impossibility for the participants. The findings have also depicted a picture of young people who are trapped in a vicious cycle of one of life‟s harshest living conditions in terms of their encounters with parents, school and the communities they come from. Despite their hopes for a brighter future one day, participants see no end in sight for their suffering at the hands of this unforgiving, destructive drug at this point in time. / Educational Studies / M.

Indiana University-Purdue University Indianapolis (IUPUI) / Methamphetamine (MA) is a widely abused psychostimulant that has been shown to evoke an array of neurobiological abnormalities and cognitive deficits in humans and in rodent models (Marshall & O'Dell, 2012). Alterations in cognitive function after repeated drug use may lead to impaired decision-making, a lack of behavioral control, and ultimately the inability to abstain from drug use. Human studies have shown that alterations in neurobiology resulting from prolonged MA use may lead to a number of cognitive deficits, including impairments in executive function, learning, memory, and impulsivity. These impairments, specifically those that engage the prefrontal cortex (PFC) or hippocampus (HC), may persist or recover based on the duration of abstinence. In rodents, repeated intermittent injections of MA yield protracted changes in neurobiology and behavior, which have been shown to effectively model a number of the biological and cognitive abnormalities observed in addiction. In order to assess the temporal evolution of impaired cognitive function throughout abstinence, sensitization was first induced in rats (7 x 5.0 mg/kg MA over 14 days). MA-treated rats initially exhibited a robust increase in locomotion that transitioned to stereotypy as the induction phase progressed. Then, the effects of MA sensitization on social interaction (SI), temporal order recognition (TOR) and novel object recognition (NOR) was assessed at one-day and 30-days post induction. No differences were observed in SI in either group or after a single injection of MA. However, an acute injection of 5.0 mg/kg of MA 30-minutes prior to testing dramatically reduced SI time. Impairments in TOR and NOR were observed in MA-treated rats after one day of abstinence, and impairments in TOR, but not NOR, were observed on day 30 of abstinence. No differences in TOR and NOR after a single injection of MA or saline were observed. These data establish that after 30 days of abstinence from a sensitizing regimen of MA, the ability to recall the temporal sequence that two stimuli were encountered was impaired and that was not attributable to impaired novelty detection. These data also suggest that at least some of the neurocognitive abnormalities caused by chronic MA administration may normalize after prolonged abstinence, since the ability to detect novelty recovered after 30 days of abstinence. These data provide compelling support that, since MA-sensitization caused temporal deficits in memory, PFC and HC function may be differentially impaired throughout the time course of abstinence.
