My wife don`t like pipe tobacco or cigars. It`s a shame that I have 30 boxes of aged cubans. She don't like that I grow tobacco in the garden. Well you can`t always win:)
I have tried to grow tobacco for couple of years and it`s fun hobby.
You need to grow, color cure and ferment the tobacco. It`s time consuming but fun.

I am pretty sure that there is no evidence that pipe tobacco has affect on PSA levels.
In medical literature tobacco is not divided in different categories (pipe tobacco, cigars etc)
You should probably meet ENT doctor who can check your sinuses (paranasal sinus CT scan). If there is problen that can be treated to improve your sense of smell.
Just my thought ( I am ENT doctor in Finland).
