(Bloomberg) -- Daren Grant biked to the Bloom Room dispensary inSan Francisco on Monday to pick up some “Big Kahuna.” Instead, hewalked out with two grams of “Carolina Cam Crush” and “Bronco MileHigh.”

Grant, a 31-year-old waiter, considered what to do with his weedduring the Feb. 7 football championship. Maybe every time a teamscored, he said, he could take a bong hit of the correspondingstrain. “I would definitely give it a toke,” he said.

The San Francisco Bay area is the first region to host aSuper Bowl in a state where marijuana is readily available, thoughtechnically only legal for medical purposes. And like otherbusinesses, local pot shops are offering promotions aimed at thethrongs of visitors in town for the festivities.

San Francisco’s marijuana shops closest to fan events in thecity’s tech-heavy South of Market neighborhood are handing outcoupons for free joints, offering discounts and renaming strainsafter the two teams set to face off in Super Bowl 50 — theDenver Broncos and the Carolina Panthers. But out-of-towners areout of luck. Only California residents who have a medical-marijuana card can buy pot at the dispensaries, which operate asnon-profits.

Colorado, home of the Broncos, is one of four states that’slegalized recreational marijuana, and pot has legally been soldthere since 2014. Two years ago, when the Broncos played theSeattle Seahawks in the Super Bowl in New Jersey, the game wasdubbed the “Stoner Bowl” since both came from states whererecreational-pot use is legal.

Tailgating experience

Pot smoking in Denver has become as much a part of thetailgating experience as beer and burgers, and buying weed is ascommon as a trip to the grocery store. Games draw a rush ofcustomers to the Mile High Green Cross recreational marijuana shop,located three miles from Denver’s football stadium, owner AdamZiegler said.

“It’s a healthy alternative to drinking,” Ziegler, 38, said bytelephone.

In San Francisco, Stephen Rechif, 29, manager of the Bloom Room,said he planned to send an employee to Super Bowl City, the fanvillage at the base of Market Street in the city’s FinancialDistrict, to hand out black-and-red coupons for a free pre-rolledjoint and lighter. His dispensary, located a few blocks from theheadquarters of Twitter Inc., Yelp Inc. and Uber Technologies Inc.,features shelves lined with glass jars of marijuana plants andpot-infused foods, including bon-bons and chocolate truffles. Thetop-shelf Carolina and Bronco strains run $20 a gram.

The Green Door dispensary, a half block from where fans can snapphotos with football stars, is running a Super Bowl 50 special ontheir Blackjack, Blue Dream and Krazy Glue strains, reducing theprice to $35 for an eighth of an ounce. The dispensary has asmoking lounge upstairs, where patrons puff on bongs and joints asthree flat-screen televisions are tuned into ESPN and ComcastSportsNet. A clock on the wall is set to 4:20, a pot-culture termnoting the time to light up.

“Super Bowl is always a good week for us,” Adam Rogers, 34, theshop’s manager, said in an interview in his office, where large,clear bags of weed sat near his desk.

Ballot measure

California has a long-standing history with marijuana, becomingthe first U.S. state to legalize its medical use in 1996.Twenty-two states have followed, and since 2012, voters inColorado, Washington, Alaska and Oregon have legalized itsrecreational use.

California voters may follow suit when they consider alegalization measure in the November election. If approved,California and its local governments could reap more than $1billion in annual revenue from the sale of recreational marijuana,according to a December report by the state’s Legislative Analyst’sOffice.

The Super Bowl festivities are cutting into sales at somedispensaries as regular customers who work downtown are stayinghome this week to avoid large crowds and road closures.

“It’s hurt business,” said Jesse Smith, 29, manager at Igzactly420, located next door to the Nasdaq Entrepreneurial Center, anon-profit group that trains and connects aspiring technologyentrepreneurs. “People are turned off by the amount of traffic andthe lack of parking.”
