I think that smoking is a makrouh act , close to haram, almost haram ,why? I'm am not a scholar but in this case, you don't have to be one.
There is a hadith that " all substances containing addictions (Nasha) are haram" And Nicotine in tobbacco is undoubtedly a highly addictive substance which has no other purpose than to destroy your health, spread all that destructive smoke to people around you and let your dentist smell the bad breath from your mouth for so long :/ .
It also paves way for other addictive euphoric substances, since the same among of nicotine stops giving you the high that it gives initially and thus the dose increases per our body demands, and on comes the dope and then hashish and then dying in your sleep without even knowing it : p
So, going by that standard, I don't consume coffee and tea on a regular basis, cause they also cause addiction and dependency, but since their effect on health is not destructive and they just cause dependency, they are not considered haram. I take them once a while for fun, but not regular cause the thought of being addicted to something scares me, and also weakens your will power, yellows your teeth, dehydrates your system, and yeah hate to wash coffee tea utensils

A better alternative to smoking and tea/coffee is green herbal tea, which not only has innumerable health benefits, but also freshens you up,wakes you up,really good for digestion, hydration and easy to make, clean up after, without the addiction hang overs and stuff. But if you're on on coffee or tea, you're dependent on it like a slave : p If you don't have herbal tea, just try drinking hot water like the chinese, and have amazing health, fitness and no need for tea/coffee; hot water also wakes your brain up real good.
