Don't have any in the house (obviously)

Don't buy any. Tell yourself you've quit buying them and quiting smoking them is just a by-product of that.

Get off that never-ending, poisonous treadmill.

I don't want to give you an out, but if cold turkey doesn't work (follow the above and it will work) definitely vape instead. You can ease off the nicotine strength gradually and be rid of the addiction. Smokers of decades duration in my family have quit this way.
