Under the heading of archiving sources.(which I did not.)
To the best of my understanding It was not illegal to give free samples
of tobacco products away in adult only venues under Federal law pre-deeming
as long as other conditions were met. However there are several more restrictions
at the local and state level that may negate this.
Regarding post deeming the new federal regs specifically mention no free samples of newly
deemed tobacco products may be given away as free samples.
Found it. Here it says,"(2)(i) Paragraph (d)(1) of this section does not prohibit a manufacturer, distributor, or retailer from distributing or causing to be distributed free samples of smokeless tobacco in a qualified adult-only facility."
CFR - Code of Federal Regulations Title 21
Here it says,"Do NOT give away free samples of newly-regulated tobacco products, including any of their components or parts.

Of course I could be misconstruing something here.
