Glad to see this topic. I have 3 years in the program and have been vaping for the past year. Bottom line is that nicotine is a drug and is mood altering, but so is caffeine. The difference is that it is not making my life unmanageable. I am open and honest about it with my sponsor. I know not to trust my own thinking. I like the definition of alcoholism and addiction as a mental obsession, coupled with a spiritual malady, and a physical allergy. While working a program works the mental obsession and spiritual malady, the physical allergy is always there and I have to be weary of anything that will spark it. I steer clear of Tylenol PM cause I know that could take me out. Be careful. Talk about it in the meetings.
