2 SWGDRUG Scientific Working Group for the Analysis of Seized Drugs

3 Mission of SWGDRUG The mission of SWGDRUG is to recommend minimum standards for the forensic examination of seized drugs and to seek their international acceptance.

4 SWGDRUG Objectives Specifying requirements for practitioners’ knowledge, skills and abilities, Specifying requirements for practitioners’ knowledge, skills and abilities, Promoting professional development, Promoting professional development, Providing a means of information exchange within the forensic science community, Providing a means of information exchange within the forensic science community, Promoting ethical standards of practitioners, Promoting ethical standards of practitioners, Providing minimum standards for examinations and reporting, Providing minimum standards for examinations and reporting, Establishing quality assurance requirements, Establishing quality assurance requirements, Considering relevant international standards, and Considering relevant international standards, and Seeking international acceptance of SWGDRUG recommendations Seeking international acceptance of SWGDRUG recommendations

5 2005 SWGDRUG Process The SWGDRUG process is an international forensic science community endeavor The SWGDRUG process is an international forensic science community endeavor The role of the core committee is to vote to accept or reject subcommittee recommendations The role of the core committee is to vote to accept or reject subcommittee recommendations In order for a proposal to become an official recommendation, 3/4s of the full core committee must be present. 2/3s of those present must vote in the affirmative (YES) for a proposal to become a recommendation In order for a proposal to become an official recommendation, 3/4s of the full core committee must be present. 2/3s of those present must vote in the affirmative (YES) for a proposal to become a recommendation

7 Sampling for Qualitative Analysis Adopted by the Core Committee in January 2005 Adopted by the Core Committee in January 2005 Goal of the sampling recommendation is to answer relevant questions about a population by only examining a portion Goal of the sampling recommendation is to answer relevant questions about a population by only examining a portion This minimizes the total number of required analytical determinations, while assuring that all relevant legal and scientific requirements are met This minimizes the total number of required analytical determinations, while assuring that all relevant legal and scientific requirements are met

8 Sampling Strategy Population Determination Sampling Plan StatisticalNon-Statistical Sampling Procedure Sampling for Qualitative Analysis Sampling Scheme

9 Statistical Based Sampling A Statistically based sampling plan is required if an inference is to be drawn on the entire population A Statistically based sampling plan is required if an inference is to be drawn on the entire population Statistically selected units shall be analyzed to meet SWGDRUG minimum requirements Statistically selected units shall be analyzed to meet SWGDRUG minimum requirements Statistical approaches include: Hypergeometric, Bayesian, ASTM E-105-58 Statistical approaches include: Hypergeometric, Bayesian, ASTM E-105-58

10 Non-Statistical Sampling A non-statistical approach may suffice to answer questions related to the presence of a drug, or to address statutory enforcement levels A non-statistical approach may suffice to answer questions related to the presence of a drug, or to address statutory enforcement levels A non-statistical approach is appropriate if no inferences are to be made about the entire population A non-statistical approach is appropriate if no inferences are to be made about the entire population Examples of non-statistical approaches include: the UNODC “square root” method and examples from ENFSI 2004 sampling guidelines Examples of non-statistical approaches include: the UNODC “square root” method and examples from ENFSI 2004 sampling guidelines

11 Population Determination Population Determination shall take into account all typical forms and quantities in which the exhibit may appear Population Determination shall take into account all typical forms and quantities in which the exhibit may appear A population may consist of a single unit or multiple units A population may consist of a single unit or multiple units A multiple unit population shall consist of items which are similar in relevant visual characteristics A multiple unit population shall consist of items which are similar in relevant visual characteristics

12 Botanical Materials Addition Adopted by the Core Committee in August 2005 Adopted by the Core Committee in August 2005 Allows a properly trained/competent/expert witness in botanical determinations to identify plant material based on documented morphological characteristics Allows a properly trained/competent/expert witness in botanical determinations to identify plant material based on documented morphological characteristics Botanical competence in this context applies to those examiners recognized as professional botanists or those assessed to be competent by such Botanical competence in this context applies to those examiners recognized as professional botanists or those assessed to be competent by such Internationally, this practice is recognized as conforming to existing standards Internationally, this practice is recognized as conforming to existing standards

13 3.6 An identification of botanical materials may be made utilizing morphological characteristics alone provided sufficient botanical features appropriate for identification are observed. Such examinations shall be made by analysts competent in botanical identifications. Botanical competence in this context applies to those examiners recognized as professional botanists or those assessed to be competent by such. Identifications of chemical components contained in botanicals (mescaline, THC, opiates, psilocin, etc.) shall rely on principles of chemical identification set down in Table 1. Botanical Materials Addition
