    Swim was wondering if it was okay to take his liquid vicodin 4 days after taking methadone. He's heard reports of people not feeling anything even after not takin domes for 7 days!!!

    A bit late on the reply but it's an interesting question. As i am sure most people know, methadone has a very long half life, up to 72 hours in some cases but about 36 hours is probably normal.

    I don't know if this is entirely accurate but i have read that after 3 half life cycles the drug is considered excreted, so if we take Wikipedia's estimate of 36 hours (max) and multiply it by 3 we get about 4 and a half days which sounds reasonable to me.

    The 7 day thing could be possible i suppose, but it would depend on how long they have been taking the methadone for and what sort of doses they are taking. Methadone definitely can block other opiates if the dose is high enough because it saturates the receptors.

    How much are SWIY on mate? SWIM is on 70mls and as our body is used to such a high concentration of opioids/opiates the effect of heroin is greatly reduced.

    The point of methadone treatment is to raise one enough so they are not getting withdrawal, and it blocks the effects of short acting opiates, to help change one's using habits. At around 80mgs SWIM could no longer feel oxys or heroin.. Methadone fills all the opiate receptors and blocks other opioids when one reaches a certain dose..

    That is why then try and get your methadone put down otherwise SWIY have to take large amounts to get an effect like SWIM

    SWIM is on 60ml and only takes half his/her methadone when he/she knows he/she is going to score.

    That way SWIM can feel the gear and doesnt waste the methadone.

    if methadone is used first it will saturate your receptors as it is fat soluble you r also just toping those levels up more. then useing on top swiy wont feel as much. try useing first then toping up with green if needed. or use less of your methadone and wait longer befor having the gear. also be aware risk of od is increased by useing both.

    methadone is made to block out opiates. So yes, it does. However. I would say just come completely off the dope and switch over to the dones man. The first day wont be that great, but the second day when you dose the dose from the day before will still be in you. I dunno man, swim prefers dones over dope. lasts alot longer and easier to get.

    While some of this might be true, IMO, I would switch to Methadone for a short while and then come off of that quickly as trying to detox off methadone can be a major bitch which several threads on here are dedicated to just that

    also methadone is not made to block opiates at all !!! it just saturates so most others if taken after cant bind to receptors.

    During my methadone treatment I was told that doses over 30mls reduce the effects of other opiates, especially any euphoric effects. And swim can say that is definetly true.
    When swim got below 20mls the 'proper' heroin effects came back, and under 15mls it was as if he was taking the heroin straight.
    100mls is 'methadone saturation' and you'll get absolutely sod all noticeable from taking heroin.

    Re: Does methadone block out a bit of a hit of heroin?

    The way methadone works is, when someone takes their first dose, it goes into the body and begins to fill one's organs, then on the next day of taking the same dose, it finishes filling up the organs and begins to raise one's blood levels. Then, on the third day of taking the same dose, it raises the blood level to the max for that dose, which can be effected by metabolism, etc..

    This long acting opioid then maintains an endorphin level, so that if the same dose is taken each day, one's endorphins do not drop to the point of being sick.. When one is stabilized at a proper dose for treatment of addiction, which can vary widely from person to person, depending on their tolerance and metabolism, among other things, then they can often skip a day, without really noticing any withdrawal. The methadone stays in the receptors longer than any short acting opioid, so this causes any short acting opiate transmitters to not bind to the sites, resulting in a decreased or even no feeling at all.

    If one desires to use methadone as a supplement, and wishes to remain able to use shorter acting opiates and experience effects, they should keep their methadone dose low enough to keep from getting really sick, but not high enough to notice no withdrawal symptoms, as this is the point where many receptors are full, but not all of them. The shorter acting, more euphoric opiate transmitters can bind to unfilled sites..

    As stated above, this dose can vary widely from person to person depending on multiple factors, but for SWIM, when he was beginning methadone, he stopped noticing as strong effects from heroin, at around the 50-60mg level, and by 80mgs a day, he could no longer feel any of what his usual dose of heroin would normally do. At about 40mgs, SWIM wasn't totally comfortable, but noticed that when he used heorin, the effects seemed stronger when mixed with the methadone, than a proper dose of heroin alone..

    Hope this helps..

    Re: Does methadone block out a bit of a hit of heroin?

    yes, it's rght, methadone blocks heroine when methadone is taken in doses
    of 20 - 30 ml / mg.
    however, SWIM is on 80 mg and tried some dope that hit the area some
    while ago, was estimated 70 % at least. SWIM did a hit, and felt a nice
    rush, but the effects somehow aren't that strong as when taking heroin
    without any other substance. dangerous for newbies is, that they take their
    methadone and then start iv'ing heroin. then they say "hey, i feel nothing,
    so now let in more of the stuff. that could be lethal...

    how much is a blocking dose of methadone?

    i am sorry if this has already been answered, i searched the forum and couldnt find anything but i have been told that methadone does not block your opioid receptors yet some people say it does. swim goes to the methadone clinic everyday and is up to 140mg and has noticed that large amounts of herion used interveniously (.5g in one shot) does not have any effect on them at all. where as the same amount would get swim to a nice warm place but now they dont even get a rush... and someone at the same clinic is on 180mg and claims that they still get high off a smaller amount of diesel. i know everyones body is different, it just doesnt make sense to me. could anyone help swim out?

    Re: how much is a blocking dose of methadone?

    A lot of reports that Red Rock has read say that 70mg is the level at which methadone "blocks" any other opiates. Red Rock has heard reports from methadone blocking people from using heroin as low as 40mg-80mg. Methadone doesn't block like buprenorphine, but instead saturates the opiate receptor sites enough that no other opiate can get through...Opiate antagonists can get through however such as naloxone or naltrexone.

    Re: how much is a blocking dose of methadone?

    Swim was able to get high on methadone and on buprenorphine (suboxone). He didnt really mess with heroin when on high doses of suboxone but when he got down to lower doses like 2-4mg he was able to do a dime bag of H and feel damn nice. :) I agree with the whole thing about methadone just kind of taking over. The high for swim was less when on methadone but he still felt it. He got up to 180mg of methadone too and was still using. Who knows though, it may have just been a mental thing for him at that time.
    Sorry that this post didnt really give any factual information like what was being asked for. Just thought I would share swims personal experience with what was in question. ;)
