What kind of cigarettes did Sylvia Plath smoke?

Answer 1

Sylvia Plath was a lifelong anti-smoker, though she did begin to smoke in the last six months or so of her life. (Ted Hughes mentions in his letters how much this surprised him).

Since Sylvia never really had time to settle in to smoking it is likely she would have smoked mild cigarettes - perhaps Embassy, Strand, or Guards.

She would not have been smoking Senior Service or Capstan.

Answer 2

Sylvia Plath was known to smoke Parliament brand cigarettes.
