Ryan, you say "The current divide between legal and illegal drugs is a bit nonsensical and arbitrary".
You may disagree with the current laws, and feel that they aren't appropriate when judged according to the real or perceived dangers of specific substances. You have that right. But whatever your position on the issue, the fact is that the laws are specific, and not arbitrary. If it's illegal, it's not permitted. Whether it SHOULD BE illegal is another question, but Amtrak doesn't pass laws. That's the Legislative Branch's job. If it's legal, it's allowed, within certain limits.
Bob Dylan: Smoking out of view of passengers? You should know better than to expect me to reveal all of our secrets, or to rat out my old co workers. I quit smoking a little over 10 years ago, but smoked for several years as an employee. We had our ways, and we did it without getting caught. Now I'm glad I quit, and my new awareness of the offensiveness of the smoke makes me wonder how we were not discovered more often.
"I'm shocked. SHOCKED! There's smoking in this (choose one) kitchen, crew car, rest room, etc."
