Hemp and cannabis are strains of the Cannabis sativa plant. They are known to accumulate heavy metals in their roots, shoots, buds and seeds. Due to this ability, hemp has been used for the remediation of contaminated soil (phytoremediation and phytoextraction).
Quantitative analysis of mycotoxins commonly involves sampling, sample preparation, extraction and cleanup followed by chromatographic methods such as GC and HPLC. The matrix complexity of cannabis often makes sample cleanup methods used for common commodities ineffective.
There is a demand for a better, more accurate and reproducible methodology to test cannabinoid potency in edibles in order to meet regulatory requirements, which vary greatly depending on country and/or state. Each food type (chocolate, brownies, cookies, candies, beverages, etc) has specific challenges, all directly impacting results, uptime and maintenance of analytical instrumentation.
This Analytical Cannabis infographic breaks down the top four heavy metals to look out for in cannabis samples—what risks they pose and which US states mandate their testing—and the ways these meddlesome metals find their way into cannabis products in the first place and cause damage to consumers.
Δ-9-tetrahydrocannabinol (THC) content in cannabis consumer products is strictly regulated in most countries worldwide. This has fueled demand for broad-spectrum THC-free oil and spurred interest in THC remediation technologies applicable at industrial scale levels.
Cambridge Isotope Laboratories (CIL) now offers solutions for testing the quality and safety of cannabis products with the launch of a variety of stable-isotope labeled and native standards of THC, CBD, and other cannabinoids to assist with testing needs.
On this week’s Opinionated Science, the team takes a look at the growing potential of psychedelic medicine. In this episode, we take a deep dive into four leading psychedelic compounds: psilocybin, MDMA, ketamine, and DMT.
