why do you still want to smoke, even though you know that smoking is bad for the body?

どうしてタバコを吸うのは体に悪くなると知っているく せに、まだ吸いたいの?

is my translation into japanese correct?

also, と, as a quotation particle, can be used with 書く, 知っている, 分かる etc, right?

どうもありがとうございます

Yep you're write, although I'd say "bad for your body" or just "bad for you". と is a quotation particle that is very flexible. You can also use it with other vebs like 感じる and 怒る.

It isn't wrong but I think any of the variations below are more natural...

タバコ（喫煙）は、体に悪い（よくない）と分かっているのに（わかってながら）（くせに）、（どうして）まだ吸いたいの？

体に悪いのが分かっているのに and
体に悪いのを知っているのに

would also be acceptable here, right?

I wouldn't use 知っているのに but yes 悪いのが分かっているのに or "to iu no ga wakatte iru no ni" etc are fine.
