Time it takes for physical dependence on oxys to develop…

SWIM knows there is prob no set rule here and everyone may be different, but it is said if you take Benzos for 14 days, even if it is the same dosage you can develop a physical dependence on the drug, do opiates generally take more or less time to develop a physical dependence on. SWIM is a bit worried, as he has been taking around 10-15MG of oxy for the past 8 days (with one day off), and he wonders if he will have some WD symptoms. It does not seem like SWIMs tolerance has gone up too much, which I guess is a good sign, he still feels good off of 10MG and 20MG is almost too much to take at one time for him.
