How can I connect with smokers or HR directors on the internet?

I teach people to stop smoking as a teleconference individually or in companies.

Most of the forums are run by competitors or drug companies that suggest drugs with harmful side effects, so I get really cranky posting on their sites.

Sites like Facebook or Twitter don’t ask if people are smokers.

I need some ideas on how to reach smokers or maybe Human Resource people so I can reach companies that are changing their smoking policy or just want to help smokers stop smoking.
