Method Man does a lot for the community. He's been spearheading the effort of methadone maintenance treatment (MMT) since it was legalized in the United States in 2002. MMT is an experimental program that helps people addicted to heroin and other opioids live without using drugs. It's now considered a mandatory treatment for all drug addicts in the United States. Additionally, Method Man also runs Wiz Khalifa's Foundation, which helps provide methadone maintenance treatment to those who need it.
