some of the keywords/titles on the site article are like following Acomplia a weight loss drug to cure obesity Is it safe to use adsense on such Diet Pills site? As I know Pill or pharmacy type sites are not allowed in adsense? But my niche is weight loss and I am promoting diet pills
Adsense does not allow the promotion of prescription drugs: https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=48182 According to the Wikipedia article, Acomplia (Zimulti) is non-prescription in the UK, a prescription drug in most of the EU, and has not been approved for sale in the United States. You might be OK if you only displayed Adsense to visitors from the UK, but it's a high risk, since it's a prescription drug pretty much everywhere else.
