Oh my, Spotted Owls...
Haven’t heard that in a long time, Maybe it’s time to get to get my bell bottoms and flannel shirts out of storage.
More seriously, our military bases and chemical pharma conglomerates are of such far greater concern this does even register
Pretty obvious you have your eyes wide shut. Fact, pesticides are used in all agriculture including weed. Illegal growers are generally ignorant or untrained in proper ag chemical application.
Most food crops are routinely washed when processed, particularly fruits and veggies and most are washed again in homes before consumption.
Dope however is processed by drying and generally smoked, so the possibility of smoking residual chemicals is high and has been demonstrated by multiple studies. And there is zero oversight on illegal grows.
If you have a green thumb, grow your own because street weed is unsafe. Not to mention high levels of fecal matter on the packaging. Dealers apparently have poor hygiene.
