Из заключения:
Limitations of this approach include the fact that we scored only harms. All drugs have some benefits to the user, at least initially, otherwise they would not be used, but this effect might attenuate over time with tolerance and withdrawal. Some drugs such as alcohol and tobacco have commercial benefits to society in terms of providing work and tax, which to some extent offset the harms and, although less easy to measure, is also true of production and dealing in illegal drugs. Many of the harms of drugs are affected by their availability and legal status, which varies across countries, so our results are not necessarily applicable to countries with very different legal and cultural attitudes to drugs. Ideally, a model needs to distinguish between the harms resulting directly from drug use and those resulting from the control system for that drug.
