I have a client who is addicted to oxycodone who is currently MIA - whereabouts unknown. I told my secretary to read the obituaries in the newspaper every day because I think that sadly, that is going to be the next time we will hear any news on him.
It's a powerfully addictive painkiller and apparently Boogard, who played with chronic pain from the various injuries he sustained in fights and in games, had developed a severe addiction to it.
