What does this even mean? What's the implication here

There usually is no meaning. Treatment has a negative connotation, treat is good.

SMOKE OLD GOLDS!

Early cigarette ads were fond of touting the health benefits of smoking, so this presumably attempts to subvert that by framing it as something to purely enjoy.

It is so JARRING to me how much perception has been distorted over the years. How could I in my youth ever perceive a bundle of burning, poisonous leaves in cheap-ass paper sending out vile smelling smoke that leaves people coughing... as cool and even sexy?

Just... what?! It's good to remember how much our culture and surroundings can shape our perception of reality and apply that knowledge to other things.

Does "straight from the shoulder" mean anything?

It's the 'straight from the toppa my dome' of the 1940s.

No thanks I'll stick to smoking old gods instead

that's a cool title

I thought that’s what the name was until I reread the ad a few times!

Apparently it has the meaning of straightforward/direct... Never heard it before either

It's kind of her to share her cigarette with the zit on her shoulder.

well, why not?

Hey now cigarettes can be cool, but the type of people who can pull it off basically consists of deranged Brits like John Constantine or Detective Halligan.
