New research highlights the devastating cardiovascular impacts of tobacco and marijuana consumption across different populations. Scientists from Wayne State University and Sinai Hospital have uncovered alarming trends in heart disease mortality linked to substance use. The studies demonstrate that tobacco and cannabis significantly increase risks of heart attacks, irregular heartbeats, and other cardiac complications. These findings underscore the urgent need for targeted public health interventions and increased awareness about substance-related health risks.

Tobacco, marijuana use to spike heart disease deaths by 50pc in next 5 years
"Tobacco-related
ischemic heart disease is still a major cause of death today" - Roopeessh
Vempati, Wayne State University
Consumption
of tobacco and marijuana is expected to spike heart disease death by 50pc in
the next 5 years, according to twin studies.
Key
Points
1
Twin studies predict massive spike in heart disease deaths by 2030
2
Cannabis use disorder increases cardiovascular event risks dramatically
3
Male tobacco users show sharp increase in heart-related mortality
It
showed that while tobacco use is expected to raise coronary heart disease death
by 40 per cent, people with cannabis use disorder are 50 per cent more likely
to experience cardiogenic shock, acute myocardial infarction, and arrhythmias.
The
studies were presented at the scientific sessions during the ongoing Society
for Cardiovascular Angiography and Interventions (SCAI) 2025 in Washington, DC,
US.
“Despite
major public health campaigns to raise awareness for the harms of tobacco and
cannabis, usage is still commonplace as we continue to see their effects on
cardiovascular health,” said James B. Hermiller, SCAI President.
Ischemic
heart disease, also known as coronary heart disease, is a condition where the
heart weakens due to reduced blood flow from narrowed or blocked coronary
arteries.
A
team from Wayne State University, US, analysed data from 1999-2020 on ischemic
heart disease mortality related to tobacco use in individuals aged 25 and
older.
Data
projected a 43.7 per cent increase in tobacco-related heart disease deaths by
2030. While the mortality trends in females decreased, males saw the opposite
with a sharp uptick in deaths.
“Tobacco-related
ischemic heart disease is not just a problem of the past. It is still a major
cause of death today. If we hope to design more targeted interventions, it’s
vital for clinicians to recognise vulnerable groups are disproportionately
affected,” said Roopeessh Vempati from the varsity
Cannabis
use disorder (CUD) is a condition where individuals have a problematic pattern
of cannabis use, leading to distress or impairment in day-to-day life and
impacts.
Researchers
from the Sinai Hospital in the US identified 1,372,419 patients who were
admitted with heart failure.
The
analysis revealed patients with heart failure and CUD experienced a greater risk
of serious cardiovascular events like cardiogenic shock (27 per cent more
likely), acute myocardial infarction (50 per cent more likely), and arrhythmias
(48 per cent more likely).
However,
individuals with cannabis use disorder and heart failure were found to be at a
lower risk of mortality than those without the disorder.
“Despite
a lower chance of death, they are at significantly greater odds of developing
other related cardiovascular conditions like heart attack or irregular
heartbeat. This understanding is necessary for doctors and public health
professionals to warn individuals of the potential side effects of consistent
cannabis use from the start, even before heart failure occurs,” said Syed
Ishaq, MD, Internal Medicine resident at the Sinai Hospital.
