Vicodin abuse comes with all the risks of opioid abuse. Over time, the body becomes used to the effects of the drug, meaning a person has to take increased doses of Vicodin for the same effects. Eventually, the body will need opioids to function normally, which is why people experience withdrawal effects when not engaged in Vicodin abuse.
There’s an additional danger: in high doses, paracetamol damages the liver. The complications of opioid abuse are serious enough; when combined with liver damage someone addicted to Vicodin may face even more severe problems.
Like all opioids, recovery from Vicodin abuse can be difficult, with painful side effects. Monitored detox in a clinical environment is key to successful, long lasting recovery.
