ABSTRACT
In the present work 12 fresh and dry vegetal species studied botanical and chemically, denominated colloquially by their consumers “supermarijuana” or crispy, due to the noticeable effects that the same produces in them. In order very terminologically to differentiate one from another one of now, that is to say the classic marijuana and this, in future we will adopt that denomination for the samples under study. Eight (08) of the analyzed samples were product of seizures of the CICPC specifically Merida-Venezuelan Delegation it and compared with four (04) samples sent by the National Direction of Forensic Sciences group GITAEF and Laboratory of Toxicology of the CICPC-Merida for its respective identification and analysis interlaboratories. I botanical identify the species, corroborating that was Cannabis sativa, probably genetically modified (GM), perhaps with aims to grant some specific characteristic to him to its psychoactive principle, constituting a product of the modern genetic engeneering. Later chemical analyses were put under such as: colorimetric tests, CCF, EUV, CG coupled to masses, comparative with the common species or classic marijuana, not demonstrating differences in its chemical composition, chemistry, but if, in the percentage content of tetrahidrocannabinol (THC), in relation average of 1/4 by gram of plant. The fresh concentration of THC in of “supermarijuana” is in the order of 20-30% with respect to the classic one. In dry by the order of 10-15%.Important to emphasize that the plant commonly worked does not respond to chemical analysis in fresh, nevertheless, “supermarijuana” if, this behavior can explain by the growth and accelerated aging of the plant without putting under it pollination with its male plant or by its high concentration in cannabinols and resins.To elucidate this behavior at the moment is object of study on the part of our group of investigations.
