In general, you must be 18 or older to purchase CBD. However, in some states you must be 21 while other states have no age limit. To make things more confusing, there are various factors that add complexity to the legal age requirement for purchasing CBD. Some states may have stricter laws if you are purchasing a product at a brick and mortar retailer vs. ordering online. Other states have different regulations depending on the type of product that you are purchasing. States are continuing to refine their laws, so it is crucial that you stay informed regarding the laws in your specific state before purchasing CBD products.
