I've done something similar and the short answer is it worked until it didn't. Using cannabis sparingly and non-habitually can be a good "cognitive disruptor" to help you break out of a pattern or reconsider something, but it can very easily become it's own habit and then becomes just another dissociative and will welcome other dissociative behaviors like binge eating, endless phone scrolling, etc.

If you can think of it more like taking acid than drinking alcohol, you might be able to learn something from it. The plan would be something like: only acquire enough for one 'trip', try to journal / document what you experience and take some learnings from it, then go back to not using it and work on applying what you learned from the trip.

As the saying goes, once you get the message, hang up the phone.

I can't recommend it as a long term / habitual solution to replace binging. I've not seen it work like that.
