CBD topicals do not enter the bloodstream, therefore it should not cause any reaction during a drug screening.
CBD topicals are typically safe to use on children but it is recommended that you consult your pediatrician before use.
Unlike THC, the structure of CBD does not fit into the CB1 receptors in the body, therefore it is non-psychoactive. However, CBD can bind to other receptors in the body and block out pain, reduce inflammation, and in some cases help with anxiety and sleep.
Studies show no conclusive evidence of it being safe or unsafe to use CBD during pregnancy. It is highly recommended you consult with your doctor before using CBD products during pregnancy.
