Never grew my own but would've liked to.
I smoked a pack-&-a-half a day for 50 years, plus chewed & dipped.
Just quit 6 months ago. Still on nicotine, though-- gum & vape. Need to quit the vape.
Nicotine's a helluva drug.
PS-- I do grow my own weed, though. Haven't bought any in about 7 years. I don't smoke that anymore, either. I make cannabutter and bake cookies with it.
