You’d be hard pressed to find an authority figure when it comes to cannabis cocktails. But Warren Bobrow, the author of Cannabis Cocktails, Mocktails and Tonics, doesn’t think that’s because the combination is a bad idea. He should know — he literally wrote the book on the subject. He’s a strong believer in a good cannabis cocktail. It’s just that everyone else (other than a few brave bar owners) is too scared to tackle the subject.
