Sources: Plurinational State of Bolivia: calculations based on coca leaf yield surveys by the United Nations Office on Drugs and Crime (UNODC) (Yungas de La Paz) and scientific studies
by the Drug Enforcement Administration of the United States of America (Chapare). Colombia: UNODC/Government of Colombia. Peru: calculations based on coca leaf to cocaine
conversion ratio from scientific studies by the Drug Enforcement Administration.
Notes: Figures in italics are subject to revision. Two dots indicate that data are not available. Information on estimation methodologies and definitions can be found in the online methodology
section of the World Drug Report 2020.
a) Owing to a lack of updated conversion factors in Bolivia (Plurinational State of) and Peru, no final estimates of the level of cocaine production can be provided. Detailed information on the
ongoing revision of conversion ratios and cocaine laboratory efficiency is available in the World Drug Report 2010 (United Nations publication, Sales No. E.10.XI.13), p. 249.
b) Values for Colombia for 2014‒17 have been revised, using an improved methodology, to take into account the participation of new actors in the processing chain from coca leaf to cocaine.
The same methodology was used for 2018. Thus, the values for 2014‒18, and hence the global total for the same years, may not be directly comparable to earlier years.
c) Conversion of areas under coca cultivation into coca leaf and then into cocaine hydrochloride, taking yields, amounts of coca leaf used for licit purposes and cocaine laboratory efficiency into
account. Current global aggregates are based on "new" conversion ratios representing the most recent data available to UNODC. See World Drug Report 2010 (United Nations publication, Sales
No. E.10.XI.13, p. 249) for a discussion of "new" and "old" conversion factors and detailed information on the ongoing revision of conversion ratios and cocaine laboratory efficiency.
d) With respect to data published in the World Drug Report 2016 (United Nations publication, Sales No. E.16.XI.7), the following amendments have been made:
(i) the figure for Colombia relative to 2008 has been revised in order to ensure a consistent implementation of revisions to the methodology, affecting the way coca production is calculated, for
the entire time series 2005‒2015 (for details, see Colombia Coca Cultivation Survey Report 2014 (UNODC, 2015) and Colombia Survey of territories affected by illicit crops 2015, Annex 3 (UNODC
2016));
(ii) totals for 2009‒2012 have been revised to rectify minor inaccuracies in data processing.
