Personally, I prefer the pipe-smoking while reading a book or sitting on the porch. Frankly, I have no worries with pipes. In fact, I smoke a pipe from time to time in my office while admiring my 16-th century globe and medival suit of armour. Cigarettes are always in supply, but they're only for late-night brainstorming sessions, high-stress situations, and post-coital opportunities. Cigars are primarily for poker nights, seedy mafia meetings, and stepping out of fighter jet cockpits.

As for marijiuana, what I don't see, I don't know, Adam. As long as I don't see the greens, I'll give you the benefit of the doubt.
