He was rushed to hospital a few weeks ago with severe chest pains and breathing difficulties, subsequently spending a week in London hospitals for treatment.
Olender explained that the chemicals in his vape led to a coronary artery vasospasm, which reduced blood flow to his heart and resulted in an ST-elevation myocardial infarction (STEMI).
He described the pain as inexplicable, requiring the strongest legal pain relief in the emergency room, and stated he could have died from the incident.
Olender has since stopped vaping and shared his experience to warn others about the dangers of e-cigarettes, urging them to quit.
