It's still only a drop in the bucket compared to overall drug-related deaths though. Tobacco-related deaths alone account for 500k deaths annually, and that's not even counting deaths related to third-hand smoke.
72,000 is just the number of sudden effects, ignoring the chronic long term effects of opiate abuse.
It the same thing with alcohol. Very few alcoholics die from alcohol poisoning, it's the long term health problems that kill them.
Actually I think the median death from alcohol is mid-30s, with alcohol-related accidents and suicides being more common than chronic health issues.
I'm not sure if drugs take away more overall years of life then tobacco, but the numbers are probably not that far off.
