14. I am aparently more competant than whoever made that chart.
Regardless of whether of not the statistics from the NIMH are correct relative to your personal guidelines as to who is an addict or not, there are sure as shit more than 1.25% who are addicts.
As for the prescription drug addicts circa 1970 - those statistics were not readily available and it's not my job to find them. It's the job of the OP who posted a crappy graphic that is so fucking terrible as to be easily disproven.
