Martha Stewart is plowing into the budding business of legal marijuana.

The 77-year-old domestic diva has signed on as an adviser to Canada-based pot producer Canopy Growth, with plans to help it develop a line of new weed-based products for both humans and animals.

Terms of the pot deal — which Canopy announced on Thursday with Sequential Brands, which owns the Martha Stewart media and merchandising brand — weren’t disclosed. But word of the agreement sent Sequential shares surging 51 percent to $1.81 in early trade after the news.

“I’m especially looking forward to our first collaboration together, which will offer sensible products for people’s beloved pets,” Stewart, made famous by her cooking shows in the 1990s, said in a statement on Thursday.

She currently hosts a show with rapper Snoop Dogg, who made headlines last year for smoking pot in front of the White House. Stewart is also well known for championing animal rights.

Canopy has also announced plans to invest between $100 and $150 million in a hemp industrial park in New York State.

Cannabis companies in Canada including Ontario-based Canopy have been pouring cash into their businesses to both fend off competition and develop new products, especially after the country approved the use of recreational marijuana in 2017.

Canopy, the world’s largest pot producer, also has a deal with Corona beer maker Constellation Brands for the alcohol company to invest more than $4 billion in Canopy to develop various drinks.
