There are no studies on the long-term cocktail effects of non-detection "traces" so i wouldn't pretend to know what those are and much less believe an algorithm which feeds on beliefs and yet-to-be-proven opinions.
The main problem here is that we're talking about the perfect crime of this century, impossible to prove nor disprove as a result of the astronomical number of savvy recipes rendered possible by a huge catalog of « sanitary » additives mixed with no combinatorial C(n, r) restrictions and a concept of « non-detection » which negates any risk from chronic use accumulation.
For example, Health-Canada's catalog of Pest Control Products once listed 96 items and there was a dozen more from another category of contaminants. So, if we spray flowers with a soup only showing non-detection peeks i'd expect at least a few signatures to repel insects having sensitive antennas while conveniently passing lab "testing"... The incentive being to "save" the harvest, not necessarily to promote public health and much less for future generations when individuals are going to get exposed for decades potentially. In clear, this means without strict regulation we just don't know today what our future youth will endure in a decade or 2 because politicians are satisfied that the amounts are said to be meaningless, which may be true of strawberries we don't normally ingest many times a day, every day all year long with our digestive system including filtration mechanisms (keep in mind cannabis inhalation is a favourite consumption method because it's direct and fast, unlike eating exactly).
So yeah, i'd only trust home-growing combined to affordable lab testing for enhanced safety in these matters, but i yet have to read a comprehensive explanation generated by an "artificial intelligence" that gets its information from bigot prohibitionist literature going back to John Warnock director of the El Abbasiÿa "lunacy asylum" in 1903 - and even beyond...
