Big Data is helping dispensaries track their customer’s habits and customize their supply to the growing demand. Big Data also helps businesses predict when they will experience their most sales, allowing them to prepare and advertise accordingly. Days such as April 20th are known money days for dispensaries as it is a sort of pot head holiday, but are there other holidays that attract more marijuana sales than others? Do people smoke more in the summer or the winter? These are the types of customer behaviors Big Data can track and show to dispensaries to make more informed decisions.
