This is such an easy problem to fix. Fresh air is pumped into the hall ways / corridor from outside. This creates pressure; that pressure has to go somewhere. It enters the units underneath and beside the entry door. If your neighbor’s door is letting in more air than yours, then they will be at a higher pressure. Because you will be at a lower pressure then your neighbors the smoke smell will come into your unit. Plugging holes, buying extra fans etc etc wont do shit... You need to let more air enter your unit to increase the pressure. Contact an air balance engineer. Yellow pages...Problem solved.
