Apparently the bioavailability is really high if you just swallow the pill. Some people like to chew them. Not really my thing, but I tried snorting oxy a couple of times, it worked, but I'm not sure if it was any stronger than just eating it.
If you've had any other opioids, maybe wait until they've worn off. Safer and feels nicer.
I always liked the burn I got snorting em lol, but chewing em works pretty well the same, just let em dissolve under your tongue after chewing, could crush em and do it the same way. These just have quicker onset, don't know if it made me any higher.
BA isnt everything. Sniffing them will hit quicker, which many of us, including myself prefer. Swallowing them will last longer, especially if taken whole. Depends on what you are looking for.
