Is the fact that alcohol is mostly legal and marijuana is mostly not merely an accident of history that has relatively little to do with the actual effects of each drug?
The amusing English comedy, Saving Grace, poses this question in lighthearted cinematic form, leavened with heavy doses of whimsy and featuring some rather remarkable displays of marijuana plants. The filmmakers stir the pot - pun totally intended - with quirky Cornish characters, dubious London drug dealers, and a sure-fire performance by Brenda Blethyn as a widow left deep in debt by her late husband's fraud.
The question at hand is what will happen when the widow turns to large-scale cannabis cultivation, hoping to get herself out of the financial quagmire. The widow's name is Grace, but the film doesn't really explore the theological implications of the word. Maybe the filmmakers thought calling her Mary Jane would be too bad of a pun.
