Solid Snake is a fictional character designed to glorify smoking, as are Tom and Jerry...sorry that is the only explanation I can offer at this time, so if you like you could leave a message after the beep. Beeeep.
Anyway, as for smoking tea leaves, well I don't see the point - I mean if you're a fan of the flavour of what you smoke, then that's understandable. But other people tend to smoke for the nicotine high (then get addicted to it), and some to relieve stress or others do it 'to be cool', but from my experience that type is very few and far between.
Though I don't smoke because I don't think it's worth it, I mean if I want to 'get off' on a drug, well getting drunk or being on a caffeine high will do me - sitting for 3-4 hours in the coffee shop this morning to do group work put a lot of caffeine in me, I didn't buy any coffee, I brought my own supply of a cheap rip off of Red Bull.
It takes blood and guts to be this cool, but I'm still just a cliche
