Not sure what 'somewhat of an opiate tolerance' means... but you did specify your ROA (oral administration). Again, if you take a dose of oxy that is consistent with your previous doses or tolerance level (take less than you would if taking the oxy alone, as you'll be taking another substance, kratom) - you'll be okay. I would make sure not to drink alcohol or take benzos (basically no other CNS depressants in particular) on top of your kratom and oxy dose/s. I'm assuming you weren't planning on it, as you only mentioned the two.
Again, all considered, you should be fine. Just 'be smart' about it. Are you knowledgeable (regarding kratom)? Ie., what are you hoping to get from this combo?
