"You're seeing a lot of these types of products like cannabis cookbooks," said Erik Altieri, spokesman for the National Organization for the Reform of Marijuana Laws. "They've always been popular among a subset of marijuana, but with the fact that more and more people from the mainstream are able to consume, there's a lot more interest."
Many pot users turn to edibles because they don't like to inhale or smell the smoke or just want variety. For many people who are sick or in pain, controlled doses of edibles or tinctures can deliver a longer-lasting therapeutic dose that doesn't give them the high.
And there's money to be made.
BlueKudu, in Denver, started producing marijuana chocolate bars for medicinal purposes three years ago. Since recreational use became legal this year in Colorado, owner Andrew Schrot said, the wholesale business has more than doubled its sales from several hundred chocolate bars sold a day through dispensaries to more than 1,000, at $9 to $17 a piece.
"There seems to be quite a bit of intrigue about the infused products from the general public and consumer, especially tourists," Schrot said.
Cooking classes have sprung up. One in Denver — led by a chef who has turned out chocolate-covered bacon and Swedish meatballs with a marijuana-infused glaze — has grown so popular that it will be offered every week in August. It's also part of a vacation package that provides pot tourists with a stay at a cannabis-friendly hotel (vaporizer and private smoke deck included), a visit to dispensaries and growing operations, and the cooking class.
Students are advised not to smoke before they come to class because there's a lot to learn about the dosing and they will be sampling foods along the way.
"By the end of the class, everybody's pretty stoned," said founder J.J. Walker.
Mountain High Suckers in Denver sells lollipops and lozenges for medical marijuana users and plans to release treats for recreational users at the end of August. The company hopes they will take off.
"People are turning the corner and making lots of money in the rec department, and we expect to almost double the business in a year," said Chad Tribble, co-owner of Mountain High Suckers in Denver.
High Times, a 40-year-old monthly magazine based in New York, has always featured a cooking column with a recipe. At least 40,000 people attended its Cannabis Cup in Denver in April, a sort of trade show that includes judging of marijuana edibles, said editor-in-chief Chris Simunek.
"Like everything else in marijuana at the moment, it's sort of experiencing a renaissance where the more people get interested, the more experiments they do with it," Simunek said.
The magazine said its "Official High Times Cannabis Cookbook" is the top-selling title of the five it offers.
It's not just a hobby or business; there's a science involved.
THC, marijuana's psychoactive chemical, must be smoked or heated — as in cooked — to be activated. When ingested rather than inhaled, it provides a longer-lasting and often more intense feeling.
