August 24, 2017 – Broken Coast Cannabis Ltd
Following the inspection at the Broken Coast Cannabis Ltd. site in March 2017 to conduct random sampling of cannabis products, a test result for a cannabis oil sample in July 2017 showed the presence of myclobutanil and spinosad, at levels below quantifiable limits.
This resulted in further sampling of cannabis products from the licensed producer site where a cannabis leaf sample indicated the presence of myclobutanil at a level of 0.017 parts per million (ppm). The licensed producer undertook further testing of their products through a third party laboratory, which indicated the presence of myclobutanil. As a result, Broken Coast Cannabis Ltd. is recalling three lots of dried marijuana sold between July to December 2016.
Myclobutanil and spinosad are not found in the seventeen pesticides authorized for use on cannabis under the Pest Control Products Act. These two ingredients are found in pest control products that are approved for use in food production.
Health Canada recommends that any individual affected by the recall immediately stop using the recalled product and to contact Broken Coast Cannabis Ltd., at the following number 1-888-486-7579.
Following an unannounced inspection by Health Canada at the Peace Naturals Project Inc. site in March 2017 to conduct random sampling of cannabis products, test result of one of the two samples of leaves collected tested positive for piperonyl butoxide at low level concentration of 0.78 parts per million (ppm). Peace Naturals Project Inc. undertook further testing on various products at their site which indicated the presence of low levels of piperonyl butoxide in dried marijuana, cannabis oil and marijuana plants. As a result, on May 18, 2017, Peace Naturals Project Inc. initiated a voluntary Type III recall for products sold between November 26, 2015 to March 13, 2017.
Piperonyl butoxide is a synergist that is combined with pesticides to increase their effectiveness. Piperonyl butoxide is not found in the list pest control products that are authorized for use on cannabis plants under the Pest Control Products Act.
May 16, 2017 – Hydropothecary
Following an unannounced inspection by Health Canada at the Hydropothecary site in March 2017 to conduct random sampling of cannabis products, test results of two leaf samples indicated the presence of myclobutanil at low level concentrations between 0.012 and 0.023 parts per million (ppm). Hydropothecary undertook further testing on various products at their site which indicated the presence of low levels of myclobutanil in dried marijuana and marijuana plants. As a result, on May 16, 2017, Hydropothecary initiated a voluntary recall for products that were sold between February 1, 2016 and May 1, 2017.
On June 2, 2017, Hydropothecary expanded the voluntary recall to include products sold between July 15, 2015 and March 24, 2017, following subsequent testing that identified lots containing low levels of myclobutanil.
Between August to October 2016, Aurora Cannabis Enterprises Inc. purchased various lots of products from Organigram Inc. and sold these lots to their clients under the name Aurora Cannabis Enterprises Inc.
On January 9, 2017, Organigram Inc. initiated a voluntary Type II recall, following testing which identified lots containing residual levels of myclobutanil and/or bifenazate which are not found in the pesticides that are authorized for use on cannabis plants under the Pest Control Products Act. These two ingredients are found in pest control products that are approved for use in food production.
The lots purchased by Aurora Cannabis Enterprises Inc. are affected by the Organigram Inc. recall, as test results for some of these lots may contain residual levels of myclobutanil and/or bifenazate that exceed any of the levels permitted in food production for these two pesticides. As a precautionary measure, on January 13, 2017, Aurora Cannabis Enterprises Inc. initiated a voluntary Type II recall of product lots sold to their clients that was produced by Organigram Inc.
During a Health Canada inspection in October 2016 at the Mettrum Ltd. site, it was observed that cannabis plants were treated with a product that contained an undeclared pesticide ingredient, pyrethrins, which is not authorized for use on cannabis plants. As a result, on November 2, 2016, Mettrum Ltd. initiated a voluntary Type III recall for products that were sold between September 30, 2014 and October 21, 2016.
On December 5, 2016, January 7 and January 28, 2017, Mettrum Ltd. expanded the voluntary recall to include products sold between January 1, 2016 and November 17, 2016, following subsequent testing that identified lots containing low levels of myclobutanil.
On December 28, 2016, Organigram Inc. initiated a voluntary Type III recall after 5 lots of product tested positive for the presence of low levels of myclobutanil and/or bifenazate which are not found in the thirteen pesticides that are authorized for use on cannabis plants under the Pest Control Products Act. These two ingredients are found in pest control products that are approved for use in food production.
On January 9, 2017, Organigram Inc. initiated a voluntary Type II recall, following subsequent testing which identified additional lots containing residual levels of myclobutanil and/or bifenazate that exceeded any of the levels permitted in food production for these two pesticides. As a precautionary measure, Organigram Inc. expanded the voluntary Type II recall to include all products produced between February 1 and December 16, 2016.
There are many more recalls at the Health Canada website, but I think you get the idea, Licensed Producers use unauthorized chemicals on your medicine. As this list of LP’s continues to grow longer every day it becomes abundantly clear that Health Canada needs to do a much more thorough inspection off ALL the Licensed Producers.
For all of you that are unaware, myclobutanil is not safe, when exposed to open flame it creates a dangerous gas called hydrogen cyanide.
In addition to the Health Canada list of approved pesticides, the LP’s also perform a process called “cold pasteurization” which means the cannabis is irradiated.
Arguably many will say that some of the cannabis supplied by the “black market” has also been subjected to any number of pesticides. No doubt unscrupulous growers will do anything to save their “cash crop”. Many growers are also medical patients and are highly unlikely to use pesticides on their crop because much of it is for their own medicine.
The “black market” is a designation that was originally used to refer the distribution of illicit drugs by drug cartels and biker gangs. Cannabis can give off some very strong and distinct odors and is very bulky making it harder to conceal. This sort of organized crime seems to be losing traction to the new “gray market”. Private growers that supply their friends and family with cannabis are a far cry from organized crime. Many of them have regular jobs and are just hobby growers, some trying to make a few extra bucks to make end meet.
So now at least with the new legislation being passed in a few weeks we all will have the right to grow our own cannabis, pesticide FREE. You can get a basic setup for under $1000 and in no time your cost per gram will likely be below two dollars. The list of Internet websites is non-exhaustive, not to mention the wealth of books on growing your own cannabis. If you can grow it outside your cost is practically nothing
What are the LP’s charging these days? Way too much in my opinion. Their product is not only overpriced in comparison but their product is also quite inferior. If growing is just not a viable option for you then you should look into having a “designated grower” do it for you for a fee, which is usually less than 50% of what the LP’s charge.
The safest choice you can make is to grow your own or source it from a grower that does not use pesticides. Really it comes down to whether or not you want to risk ending up like some of the people that used contaminated cannabis. Here is a quick sample for you
Constant Nausea Halifax woman suing medical marijuana producer after becoming ill
I can only surmise that their constant regurgitation of their mantra to “protect the kids” somehow misses the mark. What about the rest of us? Who is protecting us?
Hopefully after legalization more research will be done to support the use of medical cannabis and Health Canada may actually realize that “Cannabis is Medicine”
