I agree with most of the things most people have said here, so to summarize my thoughts:

You can do whatever you want since it is your own life, as long as you don't interfere with other members of society and the dojo. Because once you interfere with them (by coming to the dojo drunk, etc.) you're interfering with their learning, and they should have the right to avoid you in order to keep learning effectively... but if you want to make an ass of yourself, I guess that's your choice too! Personally I have nothing against most of these things, except maybe for smoking and drugs...

Some people may want Aikido to be a way of their life (like me!), but as far as I know, teachers don't prohibit these things from being done outside of the dojo... and if you want to have a wholesome life, there's nothing wrong in doing any of these things if they are done in moderation... most things are fine if they're done in moderation (even if you drink too much water you can die!)... so it's all up to you.
