A local pot activist has been ordered to shut down his dispensaries, but instead, he's defying orders even further, opting to sell marijuana to adults who don't have a doctor's note.

Dana Larsen is no stranger to controversy. Earlier this year, Larsen mailed marijuana to Liberal MPs, along with his latest book on the history of the drug in Canada.

In April, he was arrested and charged with drug trafficking in Calgary, the second stop of a cross-country tour to give away one million cannabis seeds.

And Larsen has been outspoken in his fight against the City of Vancouver's crackdown on unlicensed medicinal marijuana dispensaries. Larsen told CTV News that his business, the Vancouver Dispensary Society, sells about $10,000 of pot a day.

When the city announced its crackdown, Larsen said his business would not close, and instead would face the fines handed out by bylaw officers.

And now, Larsen is taking the fight against city hall one step further, announcing that he is selling marijuana to all interested adults, regardless of whether they have a prescription.

"They have to have ID to show us they are over 19 and that's the only requirement," Larsen told CTV on Thursday.

"I believe cannabis should be available to all adults, so that's what we're doing."

The city said it has no authority to regulate marijuana sales, which fall under federal jurisdiction. All municipal officials can do is grant business licences or take them away, with an injunction to close.

Vancouver police said this type of sale is illegal, and that those on both sides of the counter could face charges, but that enforcement is difficult.

Earlier this week, 10 pot shops in the city were hit with court orders to close, bringing the total so far this year to 27. Many owners are keeping their stores open, opting to fight the orders in court.

"We are not going to be shutting down," Larsen said.

The federal government is aiming to legalize marijuana by 2017, but with strict regulations.

"The ultimate objective of the work that we are doing around legalization is to ensure that we keep it out of the hands of kids, and keep the profits out of the hands of criminals," Justice Minister Jody Wilson-Raybould said.
