Carbon monoxide (CO) poisoning is a major public health issue in the United States that accounts for approximately 50% of poisoning cases in the nation each year and around 50,000 emergency room visits. In most instances of CO poisoning, the culprit is a malfunctioning or poorly tended heating system within the home or, occasionally, commercial building, which causes the system to leak this hazardous gas. One of the more insidious aspects of CO poisoning is that the gas is odorless and colorless, and victims of CO poisoning often do not realize that there is a problem until they begin to experience the effects of poisoning and have no choice but to seek medical attention. Unfortunately, many victims of CO poisoning die before they are able to seek treatment. This paper makes use of a qualitative, systematic literature review to examine the four major parts of the brain that are most severely affected by CO poisoning. Overall, the literature review showed that the white matter, globus pallidus, basal ganglia, and cortex are the parts of the brain most severely impacted by CO poisoning. While many CO poisoning victims do make it to the hospital on time and are treated, they may nonetheless suffer long-term neurological consequences as a result of their exposure. As such, CO poisoning is a major public health issue.

Drug abuse has now become a major public health problem in Nigeria requiring urgent attention. Although drug abuse cut across all age groups, the youths are however the most affected. This study aimed at assessing Community Pharmacists involvement in the rehabilitation of drug abuse victims. The study was carried out in Abuja Municipal Area Council, questionnaires were administered to Community Pharmacists practicing within the Area Council. A total of 176 Community Pharmacists participated in the study, and slightly above a quarter (27.43%) of them had post-graduate degrees. More than three-quarters (79.5%) of the study participants had received training on drug abuse. A total of 89.2% of the study participants had come across persons suspected to be abusing prescription medicines. Almost all (96.6%) of the study participants indicated that they are willing to advise persons suspected to be abusing drugs on the dangers of drug abuse, and 88.1% of the study participants had spoken to clients concerning abuse of prescription medicines. Also, more than three-quarters (80.1%) of the study participants indicated that pharmacists’ role in the prevention of drug abuse is very important. The study has revealed that Community Pharmacists can play an invaluable role in the rehabilitation of drug abuse victims in Nigeria.
