Condoms Safe

Does anyone know of a device for contraception other than condoms that is safe for smokers?
I am looking for a way to control birth other than condoms, diaphragms or cervical caps, which is quite effective but also safe for someone who smokes. Ideas?
my boss has been Depo for 13 years and smoked more than that and has no health problems at all or even blood pressure. She loves the coup because they have to worry about a period over 13 years.
Use a Condom. ( Safe SEX! )
