Individuals require varying CBD dosages affected by factors such as body weight, metabolism, genetics, and the specific condition under treatment. For starters, it's best to start with a low daily dose of 5 to 15 mg and slowly increase it as needed. Utokia says that you should eat one to two sweets every day, so you can slowly get used to them and get the benefits you want. Usually, the benefits start between 30 and 90 minutes after taking it and last for 4 to 6 hours.
