In Season 1 Episode 23, Rosalind Harker describes Red John as:
Just under 6 feet
Not muscular, not soft
Short straight hair
Gentle voice
Rough strong hands
Smelt of pine and nails
Likes classical - Bach
Smoked a lot

As far as I know, none of the people on Jane's list smoked, except for possibly Bertram as he had a cigarette lighter in his deposit room. Minelli was hypnotized by Jane to stop smoking which indicates he had a smoking problem beforehand. Rosalind also says he was trying to stop, hence eventually seeking Jane's help to quit.
