Methadone is a long-acting opioid agonist that is often used to treat withdrawal symptoms and cravings for heroin or other opiates. While it is usually taken orally as a liquid or tablet, injecting it directly into the bloodstream can produce effects similar to those of heroin, including a rush of euphoria, slowed breathing, and a high risk of overdose. However, injecting methadone in this way is extremely dangerous and strongly discouraged, as it also increases the risk of infection, vein damage, and other health problems.
