" It is necessary for any type of customer to know what's in their product and also what they're taking," Lawrence says. So for CBD products from hemp, check labels to see whether they state where it was expanded, and also appearance especially for those from Colorado. So in a dispensary or a retail store, ask the personnel whether they recognize where the hemp was expanded. And for products purchased online, inspect the business' website to see whether it has that details, or call the seller to ask the same inquiry.
