Three basic procedures from the "underground press" for increasing the potency of marijuana were tested quantitatively: Black Merta, Dry Ice, and isopropanol--water extraction. In all methods there was not significant change in THC, CBN, or CBD content before and after treatment. The persistence of
The recent development of modern methods for ultra high performance supercritical fluid chromatography (UHPSFC) has great potential for impacting the analysis of seized drugs. In the separation of synthetic cannabinoids the technique has the potential to produce superior resolution of positional
BACKGROUND
Since 2013 Cannabis-based preparations, containing the two main cannabinoids of interest, Δ9-tetrahydrocannabinol (THC), and cannabidiol (CBD), can be used for therapeutic purposes, such as palliative care, neurodegenerative disorder treatment and other therapies. The preparations may
Hemp nuts are mature cannabis seeds obtained after shelling and that are commonly used in traditional Chinese medicine for treating functional constipation. In this work, we screened hemp nut products, classified them, and verified the legality of consuming them. A total of 18 products were
Synthetic cannabinoids sprayed on herbal mixtures have been abused as a new designer drug all over the world since 2004. In 2008, the first compounds, CP 47,497 and JWH-018, were identified as active ingredients in these mixtures. Most of the compounds have been synthesized for research purposes and
In this study, the effect of solvent ratio of hexane to isopropanol (0:100, 50:50, and 100:0 v/v%), extraction temperature (30, 45, and 60°C), and time (30, 60, and 90 min) were investigated on the oil extraction efficiency, total phenol content, DPPH radical scavenging, peroxide value, and oil
A rapid and simple procedure using liquid-liquid extraction and subsequent gas chromatographic mass-spectrometric detection has been developed for determination of Delta9-tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabinol (CBN) in different hemp foods. After addition of
