As someone who has smoked a lot of pot and was later diagnosed with ADHD, Catie's probably better off. For most people, marijuana is harmless, For ADHD, its a not helpful.
When Catie talks about her reputation being tarnished by stories of drug use, keep in mind her special situation as the creator of Boxxy. For years people have been joking and speculating that Boxxy is a huge druggie, and as a person who wants to have a professional career, that's bound to be vexing. She's a public person, and that means rumors about her will travel farther and get bigger. Considering what she's already been through, she's really easy going. I've been following Catie for five and a half years. She almost never looks down on people, and she talks way too dirty to be a straight edge.
