Can I Use Adwords Campaign for An Adsense Website?

Wrong. People either misquote google or don't read. They readily accept PPC.
Isn't that "paid" traffic? They don't like people who are paid to visit your site.
Google's empire is based on paid traffic.

Have you read that from google?

Of course you can. Google is constantly bombarding adsense
site owners (like me) with free vouchers to spin their
site on adwords. Specifically your adsense sites.

Using PPC for adsense sites is perfectly within adsense TOS.

You have to follow the rules. Adsense cannot be the only or
majority of the site's revenue. And of course, the site must
follow adwords guidelines.

In fact, google case studies and examples on adsense are
almost always a site that is monetized by something else.
Why? Because that's a perfect storm. Those are the
sites google actually wants using adsense. Those that
are not dying for an adsense click. Those people do dumb
things.

The problem is that people think they will get rich on clicks.
They probably won't. They will be lucky if they break even.

Try something else.
