For a CBD beginner, it is recommended to start with a low dosage, typically around 5-10 milligrams (mg) of CBD per day. This allows the individual to assess their body's response and tolerance to CBD. After starting with a low dose, they can gradually increase the dosage by 5-10 mg every few days until they achieve the desired effects. The goal is to find the minimum effective dose that provides the desired benefits without experiencing any adverse effects.
