Definitely spread it out over time. Like cygnustaxt said, I get really tired over the day though when I do this. I smoked a bowl this morning followed by a joint in the afternoon. By 6 pm I was so damn tired and eventually passed out for an hour or so. I just drank some coffee and now I'm good to go. It's getting later so it's about time I smoke another bowl.

I dont know. It just depends on preference and the person.
