Smoke a joint and relax. All those feelings of anger and frustration will just go away. Nothing except what to eat will be on your mind. 
Weed solves all problems
Honeslty, that seems more of something that treats the symptoms of tempermental issues rather a solution.
Depends on the issue causing tempers to rise. If it's something small, like say girlfriend/boyfriend is hassling you are about something trivial, a joint is perfect way to help ease the tension. I'm not advocating to use it to solve major life problems, but it will help calm down and think about a solution in reasonable sense of mind rather than one of anger.
