Throw it away. Life's too short, I have found. You could be smoking something decent. Seriously, if you want to try and save compromised tobacco, from now on I'll send you mine that I consider beyond resurrection. As a bonus, I'll throw in "mystery" concoctions that I don't like and don't know what they are. A world of discovery awaits you!
The downside is you might have wait a year or so until I "make" more. I mean, I toss it, ya' know?
