Neutral cannabinoids with a pentyl side chain— for example, cannabidiol, tetrahydrocannabinol, and cannabinol— are générally accompanied by homologs with a propyl side chain, of which at least one has psychotropic activity. Samples of hashish and marihuana from Asia especially sometimes have abundant amounts of propyl cannabinoids, the quantities being of the same order as that of the accompany...

This chapter provides an overview of nationwide trends in the illegal traffic of methamphetamine, methcathinone, cannabis, and crack cocaine. Methamphetamine and methcathinone, both powerful stimulants, are manufactured in clandestine laboratories located primarily in the western and midwestern United States, respectively.

The extraction and purification of nucleic acids is the first step in most molecular biology analysis techniques. The objective of this work is to obtain highly purified nucleic acids derived from Cannabis sativa resin seizure in order to conduct a DNA typing method for the individualization of cannabis resin samples. To obtain highly purified nucleic acids from cannabis resin (Hashish) free fr...
