Should i ask this cool lady who lives next to me to buy me cigarettes?

I actually want primetime flavored cigars, not cigarettes. But there is some cool 40 year old woman who lives next to me and is awsome who talks to me on facebook and is cool when i see her, should i risk my good reputation by asking her to buy them for me? It's not a big deal because its just flavored cigars and i'm 17. Should i ask her by facebook or in person(indirect to avoid awkwardness, person to be straightforward) p.s do not judge.
