Fireworks shows have long been a tradition on the Fourth of July. Another tradition may also soon emerge: Americans smoking marijuana.

According to a report by cannabis technology company Akerna, roughly $206 million in legal national cannabis sales are expected for the holiday weekend. Akerna noted that the surge would start Friday with about $91 million in sales, up 60% from an average Friday. Saturday is expected to bring in $72 million in sales while Sunday would see $43 million.

Sundays are historically the lowest sales day of the week, but sales will be inflated with the holiday. Thirty-eight states allow for legal cannabis purchases.

"Year over year, we've seen a 23% increase in the number of products consumers and patients are purchasing for the 4th of July holiday weekend," said James Ahrendt, Business Intelligence Architect at Akerna.

Marijuana sales during the holidays can be compared to alcohol sales. The growth of marijuana use and acceptance has become an economic booster.

A survey in April from Pew Research Center showed that nine in 10 Americans favor some form of marijuana legalization.
