Thank you all for your responses. I am in NA. My primary drugs were alcohol and opiate. I know most people don't think it is a relapse, but I struggle to understand how it is not. Here's why I feel guilty: I used a drug (nicotine) with no legitimate reason besides to feel the desired effect, and it did alter my mood and mind. And I repeated the experience, and there was craving. So, if that's not a relapse, what is? When I've talked to some people they say they never stole, lied, etc. for cigarettes, but I never did those things for pot and I still don't smoke pot and would obviously consider smoking pot a relapse as would most everyone else.
