As a sober guy, I can tell you that weed isn't sobriety. I know some people who have quit drinking and started smoking, and while they might not be as inebriated as they once were, it's not a program of recovery and accountability either.
It's a bargain, and in my case, a fools errand. Upon trying it in the past eventually weed needed beer to go with it.
Real sobriety is a spiritual physical and moral revitalization.
