For me, I find a lot of people binge drink, these binges don’t go on as long as drug binges because you pass out or die before a few days is up. Amphetamine for me is the most likely to maybe not start a binge, but allow you to continue it well beyond what you could manage on any other drug, including coke. As for opioids, I’ve done a few days on them but probably no more than 2/3 days where as amphetamines, I could say WAY MORE than 2 weeks.
Think the best answer is that people will binge on their drug of choice given the chance, whether that be cannabis, coke, speed, alcohol, etc etc..
EDIT: in answer to the actual question, the drug most likely to lead to a binge is alcohol, unquestionably. Almost every person will be more likely to try, or do something they wanted to avoid, or just be much more likely to overindulge in any other drug when drunk.
