I'm not sure, but personally I think they're both bad in different ways.
I keep hearing lately how sugar is worse than cigs...what do you guys think??? That's all. Lol.

Maybe one way it's "worse" isn't so much in its effect as the fact its so damn hard to avoid? Give up cigarettes and you don't find nicotine is surreptitiously added (under all sorts of names) to everything you buy. Also, we don't give cigarettes to our children from a young age as a "treat" and help them onto the road to addiction? Sugar is still seen as a benign, "ok if done in moderation" substance ... that (mis)perception makes it even more dangerous.
Long term, because we have made it ubiquitous in our diets, we may find it causes a more widespread health timebomb than cigarettes ever did/will?
I was actually thinking about this sort of thing the other day and I'd say as bad as alcohol and tobacco is, there are probably more, even worse, consequences from all the sugar "we" ingest every day...
My friend and I were comparing sugar to cigarettes at work last week! Which is "worse" probably depends on how often and in what amount you abuse them (and if you have any existing preconditions). If a person binges on sugar regularly (like many people) and only has an occasional "social cigarette" (say once a month), then the sugar's likely doing more harm than the smoking.
Either way though, I like making this comparison for people when discussing sugar with them. People don't realize how addicting it really is! Most people just thing they "like" sugar, or that it "tastes good". They don't realize that it's actually a seriously addicting substance (in many ways!).
