We've found a fan in FHM Latvia, who say that Firefly is perfect if you are looking for the "...legal and healthy harmless stuff. Firefly make it real..."

Apparently the translation reads something like "New stimulants. Six herbal and legal ways to feel better. In modern stressful life we cannot go without pick-me-up drinks, so in order to care for yourself, you have to choose legal and healthy harmless stuff. Firefly make it real."
