Oxycodone is pretty overhyped. I can achieve the same efffects from 300mg of Tramadol, an unscheduled opioidm as I could with 20mg of OC. And that is coming from the opioid comparison chart AND from personal experience.
I voted alcohol because getting buzzed sucks and getting drunk as fuck sucks because you don't remember shit. I've also heard from friends who have tried cocaine that it's really overrated.
Honestly, weed is the most overhyped. People talk about it all the time, and it's better than alcohol I agree, but people don't talk about the 'alcohol high'.
