Are you going to call her just to further hook up with her or to really cultivate a friendship and go out and do something together? Based on what you know, is she someone you're really interested in a potential friendship/romance with or just someone you want to see if you can get over on?

It you're not just out to nail her, give it a day and a half and call her. Too soon might make you look overly eager. Too late and you risk "losing the moment." You might also think about the situation for a bit and consider whether or not she might be only interested in you because you were the guy with the weed.
