Thanks for requesting me. Here's the relevant part of the statute under which you have been charged:
Section 1097.5 Prohibited uses.
No person in a terminal, station or train shall:
a. Block free movement of another person or persons, lie on the floor, platforms, stairs, or landings, or occupy more than one seat;
b. Create any unreasonable noise by any means. Use of radios and other sound-producing devices on trains must be accomplished by means of headphones or earphones and must be inaudible to others;
c. Throw, drop or cause to be propelled any object, projectile or other article at, from, upon or on a facility or train;
d. Drink any alcoholic beverage or possess any opened or unsealed container of alcoholic beverage, except in premises or areas allowing the sale or consumption of alcoholic beverages, such as on trains or platforms or in bars or restaurants;
e. Consume any controlled substance in any part of a terminal or station, except pursuant to valid prescription;f. Enter or remain in a terminal, station or train while his or her ability to function safely in the environment of the terminal, station or train is impaired by consumption of alcohol or by the taking of any controlled substance;
The penalty is a maximum fine of $50 and/or 30 days in jail. It would appear that it is a violation rather than a crime and the worst case scenario is probably the fine unless there's something highly unusual abou tthe case. But it would be better to get the matter dismissed altogether or adjourned in contemplation of dismissal. A lawyer could help you get that done.

It should be fairly inexpensive -- in the hundreds as opposed to thousands -- as it would be rare for something like this to require more than one court appearance.
