It is critical for radiologists to recognize complications related to drugs of abuse as well as iatrogenic effects of various medications. Imaging abnormalities indicative of these complications can be appreciated at both magnetic resonance (MR) imaging and computed tomography (CT). The CNS complications of these drugs include neurovascular complications, encephalopathy, atrophy, infection, changes in the corpus callosum, and other miscellaneous changes. Prescribed medications or medical therapies that can affect the CNS include immunosuppressants, antiepileptics, nitrous oxide, and total parenteral nutrition. Drugs of abuse affecting the CNS include cocaine, heroin, alcohol, amphetamines, toluene, and cannabis. The central nervous system (CNS) is a target organ for drugs of abuse as well as specific prescribed medications. Various drugs are associated with serious complications affecting the brain, and it is critical to recognize the imaging findings of these complications to provide prompt medical management. Drug abuse is a substantial problem in society today and is associated with significant morbidity and mortality. ![]()
