We present the case of a 51-year-old male admitted for cardiovascular complications in the face of concomitant chronic methamphetamine and cannabis use. Upon further assessment, the patient exhibited cardiotoxicity, including acute to chronic congestive heart failure (CHF) exacerbation, hypercoagulable state, and electrolyte abnormalities. Cardiotoxicity secondary to chronic methamphetamine use has been established. However, marijuana's cardiovascular effects have not been well established. Even less information exists about the simultaneous use of methamphetamine and cannabis. With increasing interest in the use of marijuana for medical purposes, it is imperative to study any corresponding toxicity and adverse effect profile. The worldwide pattern of drug co-administration also brings the importance of this topic to light. This case report serves to provide insight into this information gap.
Keywords: cannabis; cardiotoxicity; chf; congestive heart failure; marijuana; methamphetamine; tachycardia.
