Romulan Ale is illegal in the Federation for decades, but both Kirk and Picard and their senior crews are seemingly able to acquire it without too much difficulty, implying that enforcement of the ban may be somewhat weak or that prosecuting offenders is considered a low priority.
What is the official penalty for unlawful possession of Romulan Ale? Six months of community service scrubbing bird waste off the Golden Gate Bridge? A year in jail? Death? Is any hint ever given as to how serious a crime possession of Romulan Ale actually is?
