Kratom is much better than Methadone as you are then addicted to Methadone and withdrawal from Methadone is MUCH worse. I have seen someone who was mildly dependant on Opiates given a much higher dosage of Methadone that actually increased their tolerance to opiates and pushed them further into opiate dependence.
Kratom has almost no physical withdrawal symptoms and is a heroin addicts best option to try to kick the habit. This is the absolute worst thing that can be done given the amount of heroin addicts that were created by the DEA's crackdown on legal opiate prescription pain relief.
