The analytical methods were obtained from peer reviewed literature, have been used as part of international or federal monitoring programs for cannabis, and have been verified for their scientific validity. Methods other than those presented in this monograph may be scientifically valid and provide reliable results. However, all methods must be verified as being scientifically valid prior to use for regulatory compliance. In the United States, cannabis is a Schedule I controlled substance under federal law; therefore, any use or pos- session of cannabis and its preparations is illegal except pursuant to the compassionate use Investigational New Drug exemption.PREVIEW These standards are not intended to support, encourage or promote the illegal cultivation, use, trade, or commerce of cannabis. Individuals, entities and institutions intending to possess or utilize cannabis and its preparationsCOMPLETE should consult with legal counsel prior to engaging in any such activity. The citing of any commercial names or products does not and should not be construed as constituting an endorse- ment by the American Herbal Pharmacopoeia. Additionally, the reliability, and therefore ability to comply with state or federal regulations, of any conclusions drawn from the analysis of a sample is dependent upon the test sample accurately representing the entire batch. Therefore, when performing all analytical tests, a formal sampling program must be employed.
