To ensure the legality of buying CBD products online, you need to make sure the company you’re buying from is reputable and that the product was made from industrial hemp with less than 0.3% THC content. While transporting marijuana across state lines (from legal to non-legal states) is against the law, transporting hemp and hemp-based products is safe. Remember, millions of people all over the US (and the globe) are using CBD products every day to effectively treat their medical conditions.
