A total of 210\u2009817 adult cannabis users were identified and matched 1:1 with 210\u2009817 ibuprofen users using propensity score matching across 17 baseline variables, including demographics, cardiovascular risk factors, and medication use. The primary outcomes were incident diagnoses of atrial fibrillation\/flutter (AF\/AFL), paroxysmal tachycardia, premature beats, and ventricular tachycardia\/fibrillation (VT\/VF).

The most pronounced relative risk was observed for VT\/VF, with 97 versus 35 cases (HR\u2009=\u20093.078, 95% CI: 2.089\u20134.533,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
