Surfed across this today, and thought I would pass it along. It is a list ranking the addictive properties of various drugs. Drugs are ranked based on "how easy is it to get addicted?" and on "how tough is it to quit?"

These two questions were given to a community of addiction experts, who ranked each drug on a variety of measures. The scores below reflect the ranking scores offered by these addiction experts. The numbers are only relative opinions, and are based only on the experience and expertise of experts in the field. In other words – these are just opinion scores, but interesting none the less.
