Recent clinical findings indicate a significant rise in cardiovascular-related deaths associated with tobacco and cannabis use. The data, presented at the Society for Cardiovascular Angiography & Interventions (SCAI) 2025 Scientific Sessions, highlights alarming trends that necessitate immediate public health action. Researchers predict a substantial increase in coronary heart disease mortality due to tobacco use over the next half-decade, while individuals with cannabis use disorder face heightened risks of severe cardiac events.

Both tobacco and cannabis remain widely consumed substances in the United States, with nearly one-quarter of Americans reporting recent tobacco use and over a tenth engaging in cannabis consumption. Despite extensive public health campaigns aimed at reducing their usage, these substances continue to impact cardiovascular health significantly. Studies reveal that Black women and American Indians are particularly vulnerable to tobacco-related ischemic heart disease, experiencing disproportionate increases in mortality rates. Moreover, cannabis users with heart failure exhibit elevated risks of acute myocardial infarction and arrhythmias, underscoring the urgent need for tailored interventions.

The implications of these findings extend beyond individual health concerns, emphasizing the necessity for targeted prevention strategies. Healthcare providers must recognize the disparities among racial and geographic groups affected by tobacco-related heart conditions to develop more effective treatment plans. Additionally, the unexpected discovery that cannabis users with heart failure have lower mortality rates but higher risks of other cardiovascular issues calls for further investigation into the complex effects of substance use on heart health. By fostering awareness and implementing evidence-based interventions, society can work toward mitigating these rising health challenges and promoting overall well-being.
