Are they drug friendly, or are they stoners? In my experience it's not so much needing to be high to eat as it is the craving to get high outweighs that for food, then when you get high you forget to eat. Then when it begins to wear off all the hunger hits you and you eat a whole pizza and a bag of Doritos right before falling asleep.

When the first thing on your mind when you wake up is smoking weed and that's your primary activity throughout the day, food just becomes secondary, so the idea of eating without smoking first is just not realistic.
