Is it safe to consume Oxycontin and penicillin at the same time?

It's never safe to take heroin....well that's what they say. I found heroin to be quite safe, in any amount, and have absolutely no interaction whatsoever with my hefty prescription regimen. It has enhanced my life in many ways. Dean's list, love life off the charts, and it has opened my eyes to philanthropic pursuits. Obviously those who claim it's addicting have never tried it. All in all, heroin is obviously a wonder drug the pharmaceutical cartel would bad mouth lest they lose their inestimable profits. Is that a needle hanging from my arm? (Why'd my mother leave me?) Gotta go now.
