Replacement could imply more than habitual use of substances. I've found the hardest part of not drinking to be the loss of the sociable activities I engage with while drinking. I've certainly used marijuana as an "intermediary" between drinking and not drinking as it seemed like a way to engage with inebriation without drinking and later would stop using marijuana when I realized I was enjoying my activities more or less the same with or without its use.
