Introducing CannaDad's new Cannabis Cup category:
~Highest PPM residual solvent Award.
It has been brought to my attention that my recent postings on Social Media about certain producers oils and my “award” for highest ppm residual solvents in their extracts. Some people have gotten offended by my approach and the wording of my criticisms. There is no reason to take offense, instead take to change-
What are residual solvents?
Let me be clear:
If you are a producer of cannabis, a cannabis infused product or concentrate of any sort then you should strive to make the cleanest, purest and most medicinal products possible, you are not working for you, you are working for the consumer- whether they are a patient or recreational user. Without the consumer there would be absolutely no reason for you to be producing anything. A producer should value the opinion of the consumer above all else- this is basic business practice.
A cannabis competition is supposed to showcase the best of the best. In my opinion this should include a pure and clean product. If you are a producer of Cannabis, a cannabis infused product or concentrate of any sort and you enter your product into a cannabis competition (High Times Cup, Secret Cup, MMJ cup) that is publicized and the biggest award possible is industry fame and notoriety then you have to be willing as well to field any criticisms that may come your way. Public attention comes in a variety of forms.
#1. Better your product.
#2. Do not enter a competition where your products lab results are public.
#3. Don’t make products if you cannot better them.
The controversy that I knowingly created surrounding industry competitions is a means to push for bettering of available products, holding producers accountable for mistakes, lackluster techniques or less than ideal products and to raise the awareness and expectations of all patients and consumers. The discussion and issues surrounding high ppm residual solvents in medicines and recreational items is one that needs to be had.
Here are some examples of lab results that show various ppm levels in different producers products. When you view these, notice that amount of concentrates with <10ppm residual solvents.
Actual Results per Analytical 360 Labs.
The United State Pharmacopeia has established a general guideline including limits concerning residual solvents in food and water products.
“Residual solvents as defined for pharmacopeial purposes: residual solvents in pharmaceuticals are deﬁned as organic volatile chemicals that are used or produced in the manufacture of drug substances or excipients, or in the preparation of drug products. The residual solvents are not completely removed by practical manufacturing techniques.”
Residual Solvents: Solvents to be Avoided, Known human carcinogens, Strongly suspected human carcinogens, Environmental hazards
Residual Solvents: Solvents to be Limited Non-genotoxic animal carcinogens or possible causative agents of other irreversible toxicity, such as neurotoxicity or teratogenicity solvents suspected of other signiﬁcant but reversible toxicities.
Residual Solvents: Solvents with Low Toxic Potential Solvents with low toxic potential to humans
[NOTE—Class 3 residual solvents may have PDEs of up to 50 mg or more per day.]*
“Unless otherwise stated in the individual monograph, Class 3 residual solvents are limited to not more than 50 mg per day (corresponding to 5000 ppm or 0.5%). If a Class 3 solvent limit in an individual monograph is greater than 50 mg per day, that residual solvent should be identiﬁed and quantiﬁed.
There are no long-term toxicity or carcinogenicity studies for many of the residual solvents in Class 3. Available data indicate that they are less toxic in acute or short-term studies and negative in genotoxicity studies.”
Acetic acid, Heptane, 1-Butanol Methyl acetate, 2-Butanol, Butyl acetate, Methylethylketone, Pentane, Ethanol, 1-Pentanol, Ethyl acetate, 1-Propanol, Ethyl ether, 2-Propanol, Ethyl formate, Propyl acetate and Formic acid
Each of these solvents as per the US pharmacopeia has a daily limit of </=5000ppm. If one gram of concentrate is analyzed and the results show a residual solvent level of over 5000ppm then this concentrate would violate USP standards and limits defined. Therefore every single concentrate, liquid or product produced should fall below the 5k ppm standard at any given time. Concentrates, liquids or food products that enter a competition for best in class should go above and beyond the call and reduce those residual solvents to <10 ppm, then and only then can they be considered best in class.
Controversy = Change
When I called attention to the high levels of residuals in the 2014 PacificNorthwest Secret Cup entrants, the founder of the cup, Daniel de Sailles, made this statement in response:
“It was not a part of the rules to disqualify anyone based on test results, and I believe the rules are a contract between competitors and I. No, even that high number is not going to hurt anyone. Yes, of course our goal should be zero ppm period. Moving forward we are going to implement a residual cutoff/dq (disqualifying) point. Now, think on this: No one would have anything to talk about if the contest didn't happen and we didn't share the test results with the public. The main point of The Secret Cup is for hash makers to do better, to generate data, to improve our craft. When people enter the Secret Cup they know they're putting it on the line, they will be put on blast good or bad. How many other events happened this year where the results aren't released?”
The controversy that my concern created effectively created a change that will help lessen the risk of residuals while at the same time raising the standard of the Secret Cup franchise. My hat pin covered hat is off to Daniel for taking the opportunity to make these changes instead of taking offense.
Watch for coming rounds of “CannaDad’s Highest PPM” awards in this years’ Cannabis Cup Circuit.
