People who buy medical marijuana online may not get exactly what they expect when their package arrives in the mail. Researchers searched online for medical marijuana products and bought 84 products marketed as containing CBD from 31 different companies. Overall, 36 products, or 43 percent, had more CBD than was indicated on the label and another 22 products, or 26 percent, promised more CBD than was actually included. Liquid versions used with vaping devices had inaccurate labels 88 percent of the time, while oils were mislabeled about 55 percent of the time.
