The reason I questioned the numbers on that table is that alcohol did not kill all those people, I suspect. I would guess that car crashes while drunk killed most of those people. It is a fine distinction... Not that many people are actually killed by alcohol itself, rather what they do on it. Hard drugs kill people all by themselves.
Well there were only ~43,000 accident related deaths TOTAL so if you subtract ones that were not DUI related, and ones accidents from other drugs, you can maybe subtract 20,000 from the alcohol number.
Also, the drug deaths are also pushed up quite a bit. If they die and had taken a substances it's marked as one of the causes of death (true with cigarettes also), whether or not it was the main cause of death.
