Highest High: How Potent is Your Pot?

For obvious reasons we can’t list the Cannalytics Cannabis Fingerprint and THC Test Kit as the Bad Ass Toy of the Week: It’s not a toy.

In fact, this home chemistry kit is 100 percent legit. Alpha Nova Diagnostics, a World Health Organization compliant company, is a Dutch chemical and biochemical lab that produces home test kits for pesticides, heavy metals, and oh, yeah, weed. The Thin-Layer Chromatography (TCL) technique the kit is based on is the same used in testing for trace amounts of organic compounds. What works to figure out the makeup of your fertilizer, also works to figure out the cannabinoid composition of your chronic.

Not to harsh your buzz, but here’s why this test is such a big deal for bong-lovers: due to the Schedule 1 Controlled Substance classification of marijuana, few labs in the U.S. will test weed for potency, unless the DEA approves. Of course the police will happily test your maryjane, but chances are you’re not getting it back. You are guaranteed one phone call though.

The lack of testing means that no one can say for sure how potent pot is. The National Institute on Drug Abuse (NIDA) regularly reports on the tetrahydrocannabinol (THC) concentration in marijuana, but the stash tested is what law enforcement officials have confiscated, and the range in reefer quality and THC percentages is pretty large. Some of the sticky rates THC concentration in the high 30s, but some rates 0. It averages out to 4.53 percent, but all this really means is that while there is some seriously potent pot on the streets, there’s also some buds barely registering anything.

THC levels differ according to plant, with females often having higher levels, as do more mature plants. This is because as cannabis grows, the chemical composition changes. Plant genetics, climate and harvesting procedures all will affect the chemical composition of the plant.

THC is not the only cannabinoid in cannabis. The other cannabinoids might not be as well known, but their presence affects your high. Some cannabinoids have anti-inflammatory affects, some are anti-anxiety, some induce sleep, and one even has been shown to suppress appetite. No muchies when smoking that maryjane.

Because of the lack of lab testing, even in the 15 states and the District of Columbia where the use of medical marijuana is legally permitted even those with prescriptions for pot can’t be completely sure of the THC levels in the weed they’re buying. And as you know if you buy off the street what you get depends on who you’re buying from.

The Cannalytics test kit can identify the type and consistency of cannabinoids, which means you’ll know what’s in the pot you’ve purchased, and what kind of high to expect. Sure, it means you have to be a bit Mr. Science about your stash, but isn’t it worth it to know what you’re smoking?

 


marijuana lab testing

A qualitative and quantitative HPTLC densitometry method for the analysis of cannabinoids in Cannabis sativa

Abstract

INTRODUCTION

Cannabis and cannabinoid based medicines are currently under serious investigation for legitimate development as medicinal agents, necessitating new low-cost, high-throughput analytical methods for quality control.

OBJECTIVE

The goal of this study was to develop and validate, according to ICH guidelines, a simple rapid HPTLC method for the quantification of Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and qualitative analysis of other main neutral cannabinoids found in cannabis.

METHODOLOGY

The method was developed and validated with the use of pure cannabinoid reference standards and two medicinal cannabis cultivars. Accuracy was determined by comparing results obtained from the HTPLC method with those obtained from a validated HPLC method.

RESULTS

Delta(9)-THC gives linear calibration curves in the range of 50-500 ng at 206 nm with a linear regression of y = 11.858x + 125.99 and r(2) = 0.9968.

CONCLUSION

Results have shown that the HPTLC method is reproducible and accurate for the quantification of Delta(9)-THC in cannabis. The method is also useful for the qualitative screening of the main neutral cannabinoids found in cannabis cultivars.
