I wouldn't necessarily consider smoking a cigarette to be 'staying sober'. Sorry but whenever I smoke one, I get dizzy, my knees get weak, I can't think clearly and I usually end up vomiting if I try to walk. I smoked a bit for a while but when I tried to substitute my weed usage with cigarettes I realized that cigarettes were much worse. I don't think weed can change the course of your actions - alcohol alters your mind state so much that you can black out and not know what's going on and make bad decision but weed isn't like that. Whenever I smoke, or when my friends smoke, we are all level headed and can think clearly. We might look like a bunch of school girls because of all the laughing but we are still able to make rational decisions. The idea that weed alters your ability to make choices or right actions is a complete myth in my opinion.
