Yep. From the article;
“Drug policy is primarily aimed at reducing the harm to individual users, their families and society. But at present there is no rational, evidence-based method for assessing the harm of drugs. We have tried to develop such a method. We hope that policy makers will take note of the fact that the resulting ranking of drugs differs substantially from their classification in the Misuse of Drugs Act and that alcohol and tobacco are judged more harmful than many illegal substances.”
This is nice because they're all scientists, but then figured it all out for the policy makers too, so they don't even have to think extra hard!! Hooray science!!
