Well I don't see a health problem with it, especially with canning jars (other than the fact that tobacco isn't known to be health food in the first place...). I do a lot of canning in the fall and there I'm bringing an entire canning jar, lid and contents to ~212 deg (full rolling boil) for sometimes up to an hour and a half. I doubt 160 deg is going to bother anything even if you left it in the oven for a week.
