I was wondering if anyone out there has first hand knowledge of how long a few medications stay in the users system. The medications are: Oxycodone 30mg, hydromorphone (dilaudid) 8mg, and Morphine sulphate 100mg extended release. I know that the majority of painkillers last aprox. 3 days in a persons system but have no idea if it differs on these medications. I mean, does the strength of the pill matter? Also, does it make a difference if the drug is extended release? I would think that it may last longer...anyone know for sure? Please give me any info you all have on this. This is for a good cause, really. Talk to you all soon and thanks in advance.

A consideration
One thing to consider is that people metabolise substances at different rates. If a general guideline tells me opioids will be out of my system in 3-5 days, I like to give it say, 7 days just to keep myself on the safer side. :)
Another potentially helpful link is http://www.erowid.org.
Some of the material may be a bit questionable, but I believe the guidelines are taken from an outside source. Overall, pretty reliable by my own experience.

You can easily calculate how
You can easily calculate how long it will take for the drug to leave the system if you know its half life. Half life is the period of time required for half of the drug to be removed from the organism through biological processes (metabolism and elimination). In other words, this means that for every X hours that passes without taking the medication the level in the blood falls by 50%. After first X hours the level is reduced to 50% of the original level, after second X hours to 25% of the original level, after third X hours to 12.5%, and so on.

There is a very BIG
There is a very BIG difference between plasma half life and time for drug clearence. Please note methadone has a long half life yet is still cleared in about the same time as opiate analogues. If you're calculating plasma half life up to drug clearence, no big deal. BUT, if you're calculating drug clearence rate back to plasma half life the consequences could be lethal.
By clicking on this link - This will open a new window so you can look at your post, and then find the drug in question on the chart.
Just remember that some ER formulations will stick around longer than regular release formulations. Regular Oxycodone + acetaminophen will not stay in your system as long as an extended release Oxycodone preparation. Same with Morphine.
