Tetrahydrocannabinol (THC) has been increasingly associated with agitation and cardiotoxicity, while cannabidiol (CBD) has been associated with neuroprotective, inhibitory states. We propose that increasing concentrations of THC as well as THC:CBD ratios seen in cannabis concentrates such as "dabs" may cause agitation and end-organ damage through sympathomimetic and serotonergic pathways.
Cannabis use is steadily rising in the United States. As the popularity of marijuana rises, new varieties of cannabis-related products are becoming available. Dabs are cannabis concentrates gaining notoriety for their significant amounts of tetrahydrocannabinol (THC) that are ultimately vaporized and inhaled for their effect. Herein, we provide an overview of recent cases of dabbing to bring awareness to the clinicians, of the significant adverse effects associated with dabs including psychosis, neurotoxicity, and cardiotoxicity.
Cases of severe iron toxicity have become increasingly rare; most cases are intentional ingestions by late adolescents and adults who present within 12 hours of ingestion. We present a case of an adolescent girl with metabolic acidosis, hypoglycemia, obtundation, and liver and renal failure of undifferentiated etiology who was eventually discovered to have overdosed on ferrous sulfate tablets 4 days before arrival. The diagnosis was made because the patient had an elevated transferrin concentration in the setting of a minimally elevated serum iron concentration and faint radio-opacities on abdominal plain film imaging. This case presents many diagnostic challenges and treatment dilemmas and is a rare report of survival in delayed presentation of severe toxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
