Ben Ward, CEO of Maricann Group, gives licensed producers (In Canada and US) a piece of his mind.
As quoted in the article:
In the past year, a few of the 52 licensed producers in Canada have been found to have pesticide contamination in their cannabis products. From what I can see, the explanations given for the presence of these pesticides don’t make sense. Pyrethrin, for instance, has been found on some medical cannabis products shipped out of certain growing facilities. However, pyrethrin does not naturally appear on plants. It has to be intentionally applied, accidentally or otherwise.
