A new Associated Press analysis finds that 157 young people age 18-23 died from alcohol poisoning from 1999 to 2005 (the most recent figures available). Alarmingly, the 2005 total of 35 alcohol deaths was the highest in the period, nearly double the 18 deaths in 1999.
Not mentioned by AP but worth noting: The number of marijuana overdose deaths during that same period was zero. As noted in a recent British Medical Journal editorial, no medically documented marijuana overdose deaths have been reported in the medical literature.
