Welcome,
My ex-abf's drug of choice was cocaine, he is a tooter.
Relapses are a common occurance. To me, it's good that he has hopped back on the recovery train.
Keep your eyes and ears open, observe what his actions are...they will speak for themselves.
Remember one thing, he will always be an addict, it's just a matter of whether he is active or not.
Keep posting, we are here for you.
