Well for the longest time I did not post this list because it freaks people out...Most times these false positives do not happen due to cut off levels...gotta get courtney to explain them she is pretty good at explaining how they have nanograms they cut off at and this can help keep the false positives down to a minimum....It can cause a false positive but it doesn't always.....Same thing with the antibiotics and if they do then you have the clinic do a confirmation test on it.......

    So I can't take an aleve? I just got antibiotics for an infection, so if thy cause false positives will te counselor believe you?

-potter407

Take the meds if your GP has prescribed them for infection. If you do have a urine screen and it comes up positive, simply take the prescription in with you, and state that you believe they can cause false positives.

If you listen too much to what causes false positives, you'd have to avoid most medications and supplements in the world!!

Correct that's what I was trying to say...they can cause false positive meaning they don't usually.

When doing a UA does the person collecting the urine ask if you are currently taking medications?  On our UA forms there is an area for current medications. Just wondering.

I once had a nasal inhaler cause me to test positive like it was adderall (dextro)... Took us FOREVER, but we finally figured it out. I nearly lost my phase level as a result... So ALWAYS make sure you have a list of EVERYTHING you've taken or been taking so you can just go down the list like a checklist if you ever have a positive and are sure you haven't done any illicit substances... :-)

It's the ephedrine in things like that that make you seem like you've ingested amphetamines.

Avoid any cold remedies with ephedrine or pseudoephedrine in them.

 @WAY To have someone like you to bring not only your own personal stories but also the information that we can come here to ASk and be Answered  is extraordinary. Not just a fellow addict but a wonderful human being proving she truly cares..
 I have been working on my recovery story to put in here although the names will be changed to protect the innocent. Which ain't me lol

I also want to shout out to Sapphire who is also a true warrior for the rights of MAT, MMT 
She is not only educated in the ways of her Country but has found the difference as well as similarities of the good old shitty USA.
I do love my Country but our judicial system sucks letting Zimmerman off   Not to mention countless others 
Kids killing kids, Mothers killing their children, now idiots that not only take their guns to a brawl but their video cameras too, also screaming "I fear for my life" against unarmed men having a birthday party with kids Who dies?.The men with no guns. These stories go on and on sometimes it is no wonder to me why I started using when I was so young.....but that is why I am here now and on the MMT program..

.
The smirk on Bush Jr's face whenever he spoke as President, makes me sick and I  think he was on drugs as well as drinking his redneck whiskey.

But hey let someone get caught driving home from their clinic here in my neck of the woods, with their methadone take homes in tow.
You will see that person not only losing their methadone but going to jail too,.for DWI . 

What a fricken   f/up mess

@review - so if the cops pull you over and you are on the way back from the clinic, they will take your TH doses off you?

What happens then, will the clinic replace them?

Sounds like a right load of BS on the part of the cops, They wouldn't do it with any other fricking medication.

    Is there any way to print this...not the comments, just the original post?? I would like to have a copy of them.

-ninny111

Take a screen shot of the first post and paste it into MSpaint and then print that? Or arrange the print settings so that the original post will all come out on the first page, and then just use that first page?

@Sapphire

We heard that too but it was a long time ago. Our clinic switched to lock boxes supposedly (I think they are required federally now) because cops were sitting out in our parking lot and pulling people over after they left and dumping all their take-homes and saying they were doing it bc 'they couldnt be sure it was methadone in those bottles' lol it was stupid so now they if they are in a locked box the cop can't open them without your permission, at least in our country/state.

True @sweetskull but even if they find a lock box these redneck cops will think you are carrying a concealed weapon and make you open it. down here (I heard this young girl crying say) 
Wishing you well with your people and yourself but just for extra measure I also hide my lock box under the carpet mat or inside the trunk.
@Sapphire Nope my clinic will not replace any medication once it is out the door no matter what the reason.
Tell ya to go to the ER or even if you have a POlice report they get freaked out if they know they got the bottles..
 I saw a young girl crying showing the owner of the clinic the report and he said it was too bad that so many people sell their meds because the bottles that these idiots sell  have their name and the clinic;s name on them
So the POlice like to come by every so often and pour them out in front of the owner....So he says
