Martha Stewart -- I'll Eat Edibles ... In the Name of Science (VIDEO)

Martha Stewart cooked up some grub Friday with Snoop, and based on what she told our photog the cuisine made her more than mellow.

Martha arrived at LAX hours before the filming "Martha and Snoop's Pot Luck Dinner." We asked her what she'd do if Snoop's recipes included edibles ... and she got all high-minded on us -- talking about science and stuff.

That's one small step for man ... because it's hard to take big steps when you're stoned.
