For this I would choose drinking as smoking really can harm you a lot worse... I haven't had either except for a little wine at church, but that is it.

If faced with this catch-22, I'd pick drinking. I'd drink a lot of red-wine for it's health benefits. After seeing what my history teacher went through who died this year from a heart attack from smoking too much, I couldn't ever smoke. 

I would choose drinking as smoking leads to all sorts of diseases whereas with drinking, the only deadly disease you are most likely to get is cirrhosis of the liver which is what many drinkers die of.

I wouldn't do both but if I have to choose, I choose drinking.
I don't like the smell from cigarettes and if you ever have seen a smoker his face, teeth and lungs you know enough (shivers).
If I would drink too much I might at least be happy before I die

Translation (because you can't hardly understand a word he says half the time):

The Ultimate Warrior has a lot of bad habits but only the ones that help me survive. Don't deprive yourself of the true power. Be a survivor. DON'T SMOKE

Drinking.
Whatever happens I WILL NOT SMOKE.
Unless my whole family dies at the same time... I'm a kid and I know how bad Smoking is, my Brother started smoking at the age of 13. Now he uses an electronic system to smoke which is a million times:
Healthier and Cheaper (I life in Belgium and we have a shop at home, if you would like to buy one, visit www.edampen.be for more information.)

I would rather be a belligerent drunk than be a smoker. At least being a drunk would be fun! With smoking you really don't get anything but being drunk is just fun so yea, I'd take up drinking as my bad habit. 

As someone who smokes and drinks I have an interesting take on this.  Alcohol can completely ruin your life or it can be a fun activities during games and whatnot.  Whether the alcohol gets abused or not depends on the person like how well they deal with the stuff. On the other hand you have some people some upwards of 3 packs a day (I smoke about a half pack a day), anyways, that much smoking is what really cauzes the serious health problems and they are more likely to happen sooner too. So I think depending on certain personalities that tell which drug they are more able to handle or some kind of personality quiz or sompin.  

As for myself I wish I could quit smoking and wish I had never started.  Even though I drink as well it doesn't screw up my life, I am able to control that drug well and with responsibility, so I would pick the drinking one.

You all are humanitarians! It's a good thing you guys don't want to do either of those things!

Though, I don't plan on doing either, I'd rather do drinking than Smoking.
It is VERY possible to drink casually, and do it once in a while as you socialise.
SMOKING is a very different story, though. Once you take even ONE, your life can very easily be destroyed. Addiction is VERY hard to get through, and more preventable in Drinking than Smoking.

*stroking fake bear* I'm so torn right now, I do both of those things... mm... if I had to choose it would have to be drinking (I just like it more then smoking)    -what are you looking at? Don't judge me-

As someone who has spent 21 years inhaling smoke and had some alcoholic beverages, I think if I were ever to become one, I'd be an alcoholic.  Give me some Coke and Crown Royal and I will be all set destroying my liver, rather than cough all the time.  The only problem is, Smoking cost less usually, so if you were on a tight budget and had to choose, well there you go.

Don't do either though, instead of wasting your money on that pay Dave with that donation button :p waste money on things that matter! 

Drinking obviously. Been a drinker for about a few years now. It's not pretty once you realize how useless it is, just to escape from your mistakes.

Drinking, we drink every Friday night so it's an easier habit to take up. Not to mention smoking cigarettes is nasty, I've tried it and stopped immediately. They smell gross, they taste gross, and they are full of toxins.

If I had to choose, then I would choose drinking. Smoking can give people lung cancer and heart diseases. People that breathe the smoke from the cigarette can also get lung cancer and heart diseases, thus I choose drinking (just as long as I don't drink too much alcohol).

Both are bad. But my opinion is that smoking seriously damages health as tobacco abuse brings lung cancer, shortens life by ten years and brings death

I would choose drinking. Drinking isn't necessarily as damaging to your body as smoking is. Trust me, both of my parents smoke, and i've seen what it's done to them so far. Additionaly, my grandad smoked. He died at 50.
