I'm 4 days post op bbl, I was told not to smoke for at least 2 weeks but try for at least a month. Would 1 a day put me at risk?

I was told that if the cravng or withdrws were too much gt a low dose e cig and I wld be fine. my prob is when I went to the phrmcy to buy 1 & check the mg of nicotine, the phrmsist told me I wld be safer to smk 1 real cig a day. a cpl hits in the morning, pt it out, & smk on that same cig all day. that my immune system is getting weak because of withdrawals, but what about the nicotine? I feel screwed! Like I'm risking infection if I don't and risking dead skin if I do!
