As a general rule, the legislative process takes a while what with committees, subcommittees and so forth. Thus a bill introduced in January likely would not make it to a floor vote (if ever, as a high percentage of bills never make it out of committee) for some months.
Probably the best way to keep up with pending legislation is
http://www.legislature.state.tn.us/. If you got the gumption you can register and set up a "My Bills" section to keep track of any pending legislation in which you have a particular interest.
I'm not doubting your info Scott. This is obviously of interest to you on even more levels than the rest of us here. Is it your understanding that the new proposed bill would remove the exemption for, "Retail tobacco stores that prohibit minors on their premises"? (Tennessee Code Annotated Section 39-17-1804(9)) Last years bill targeted only the exemption for "Age-restricted venues." (Tennessee Code Annotated Section 39-17-1804(1)). Do you know who the proposed sponsors are to be?
