I Can Smell the Cigarettes

I can smell the cigarettes;
But why? Since you ought be too far
For my nose t'sense this dreaded scent,
Sickly distance (my shield of sanity) falls to lark.
No plum fresh'ner nor perfume,
If rids the reek, will mend the wreck
between you and I 'til tomb;
'tween us is a too forte a cleft.
Pernicious youthful decisions,
de facto more strong since
tender brains 'er fertile to fissions
deeper, bridged by naught but blood, but chance--
Shame!-- hear the halfwit's heart hold hope
to, like no mortal, walk on water.

I can't find something which fits on the last couplet.
I know the meter isn't right...but I worked hard on this. So, I am proud.
