lol yes, there's so much money to be made in growing street weed and so much demand, what's the point in lacing it with anything? Fake news I used to grow, many decades ago. Hemp family has virtually zero pests so pesticide is very very rarely used. Herbicide also very rare, most street crop ( and Swiss grown CBD flower) is indoor grown so there's no need. Hemp for CBD extract/fibre production grows fast and covers the ground quickly and is so tall weeds do not grow. Unless it's certificated organic anything is possible however. Fake news for the above points is everywhere. However, poorly ventilated indoor illegal crops are prone to fungus so fungicide can be used. Nasty.. but they are grown with so much chemical fertileser and additives that it's nasty anyway!
