Tenant has been smoking inside... can I keep all of the deposit?

[Matt Gilroy]

Hello BP,

I was at my rental house this morning making a repair.  The house smells so strongly of cigarettes that I still smell like an ash tray after spending less than 30 minutes inside.  The tenant is fully aware that there is NO smoking inside.  He has been there for about 6 years.  The house needs a fair amount of work because the lack of his cleanliness.  New carpets and paint is a 100% must, especially after the cigarettes.  

Am I allowed to keep all of his damage deposit specifically for smoking if I choose not to renew his lease that is up 3/31/19?
