Question 1... Was the fire at a meth house? Question 2... If you are doing meth... Are you not also prone to heat attacks?
Not necessarily. Depends on how well it's made, how it's used, and the user's heart health.
WWII ran on speed. The Nazi's secret weapon in the invasion of Poland, and later driving the Allied army into Dunkirk was a drug called Pervitin that made the Nazis immune to fatigue and, to an extent, fear.
Once the British figured it out they started issuing benzedrine to their soldiers, because the only way to stop an army that doesn't get tired is with an your own army that doesn't need rest.
Wehrmacht records show the Nazis handed out 200 million methamphetamine pills over the course of the war. There were side effects, like crashing when you finally came off them, but there was no rash of heart attacks.
We still give speed to military servicemen under extreme conditions. The USAF pilots who bombed Libya in 1986 were taking speed because they couldn't get overflight permission from all the Euro-Weenies needed to take the direct route from England, so they had to take the long way around Spain.
There was a period after WWII (when amphetamines first came into wide-spread use) and before the advent of EPO (~1987) when the sport of professional bicycle racing ran on amphetamines. Forty or so years of thousands of men engaging in strenuous physical activity for hundreds of hours each year. And in that time there was only ever one death (during a race) that was linked to amphetamines (Tom Simpson, 1967).
So taking amphetamines (not made in your neighbor's basement) in moderation isn't especially dangerous. It compounds the tragedy of this that they published that detail because the report as much as says,
"...Also noted in the report are "other conditions contributing but not related to the immediate cause of death." Listed in this section are "effects of methamphetamine, COVID-19 positive...."
For all anybody knows, this man might have died a hero. It might be he took a reasonable amount of amphetamine to ward off fatigue because he knew people were counting on him to save their homes, if not their lives. He might have weighed the risks and decided it was worth it.
But all anybody is going to remember is his autopsy had the word "methamphetamine" in it.
