This same death Tahir cited somehow also vaped for a few months. 10 weeks to 10 years of vaping doesn't matter the heavy smoking of 40+ years + drinking did him in.  I doubt he did regular check ups with his doctors. Some of his doctors would have noted something. EVALI, again I doubt they tested him for THC vaping and VEA and just called it vaping. Yes, even a 70 year old man can do something stupid like that!
