LOL, I wouldn't of said that to tchort.
He must be on to me; I make up about 90% of what I post

Are you just guessing? you said "Probably" which indicates to me that youre guessing. Do you have a basis for your statement? Methadone and Oxycodone have absolutely nothing in common....
Im not saying that youre wrong...I dont know either way. But i dont want to take your advice if youre just guessing...
Look at the link below; this isn't a "guess", it's a hypothesis backed up by historical facts, basic chemistry and reading [free] white papers going back to the '60s.

Refer to what
Unknown says:
First, oxycodone and methadone DO have something in common. They are both mu opioid agonists.
Second, Chasing methadone, im guessing, means to increase absorption and BA of the drug. Methadone has a high volume of distribution, meaning that even IF the drug absorbed quicker, it would still acheve the same peak plasma levels, and same speed of onset as oral, IV, IM, rectal, nasal, sublingual, transdermal, buccial, etc.
My point was that a number of full mu agonist opioids are chased; including Opium, Morphine, Heroin, Oxycodone, Fentanyl. Most likely any mu agonist can be chased or smoked; the point is that mitigating factors could make this a very, very ridiculous thing to do.
Like
Unknown points out, the high volume of distribution of Methadone when it is absorbed through any route of administration makes Chasing probably the absolute worst way to consume it. Depending upon the numerous factors I listed in the
Smoking & Chasing Opioids: General Information thread, such as poor technique/charring, using a crushed pill or an extracted/purified product, using volatilization enhancers or inhibitors, etc, even under the best of circumstances you most likely won't reap the benefits of a faster onset. Instead, you will still have to wait for effects to come up, but because Chasing (even with optimal drugs, experience and expert technique) almost always lowers the BioAvailibility of opioids, you'd be wasting a lot of Methadone for nothing.
The reason for Chasing is faster onset, which makes the chemical feel stronger. The downside is less of that chemical is available to be absorbed by the body, thats the trade off. If you do not get the faster onset, and you lose some of the substance that would have been absorbed via a different route of administration, it's a lose-lose situation.
There is even a lot of debate about IV Methadone (which by default has a 100% Bio-Availibility and the fastest onset possible). Some people say they get a rush and it is faster than swallowing it or plugging it (fully kicks in after 10-20 minutes instead of 30-90 minutes). The consensus though is that even taken intravenously, Methadone acts almost the same (in regards to speed of onset, potency, etc) as it does when taken orally.
In short: Don't chase Methadone.
