Dear Brian: Neem oil is an extract of azadirachta indica, more commonly known as Indian lilac, nimtree or neem tree. Despite having “indica” in its name, this tree doesn’t carry any THC or CBD, but it does have an impact on some of the buds you’ve probably smoked throughout your stoner career. Used as an effective treatment for agricultural pests that also annoy cannabis grows, neem oil is deemed non-toxic by the Environmental Protection Agency for food and ornamental crops, and doesn’t cause any red flags for farmers who use it. But studies done haven’t included cannabis or crops meant for smoking.
