Jim Cramer's stock calls: GW Pharma, ConAgra Foods

CNBC's Jim Cramer on Wednesday gave his call on two stocks: GW Pharmaceuticals and ConAgra Foods.

To start, Cramer flagged drug-maker GW Pharmaceuticals, which saw shares spike after it recently announced plans to sell 1.7 million shares in a secondary offering. He thinks investors should take advantage of the secondary, and buy the stock.

"This is the only really legitimate marijuana stock out there. It's a British company. It's doing very well," Cramer said on "Squawk on the Street."

The biopharmaceutical company grows cannabis under license at a secret location in Britain to make an array of experimental cannabis drugs.

Cramer recommended investors stay away from ConAgra Foods right now, though.

The food company reported a "horrible quarter," including poor performance of private brands and a drop in consumer volume, putting a bad taste in Cramer's mouth. Chef Boyardee, one of its flagship canned food products, did particularly poorly, Cramer said.

"A lot of what's canned isn't selling well. People don't like canned anymore," he noted.
