This is an important question. If you didn't get them from a pharmacy yourself or from someone who has a script then they could be fakes that contain another drug. The drug that would likely be substituted in the case they are fakes would be fentanyl, but it could also be RC benzos or anything really.
But no, opiates don't usually make people wanna do it like they do on the discovery channel. But oxy is a more stimulating opioid and i'd be lying if I said certain opiates haven't made me itch for the company of a less than fully clothed person.
