- With regular heroin use, a tolerance will develop, leading the abuser to use more of the drug to achieve the same effect. As higher doses are used over time, physical dependence and addiction develop.
- Withdrawal may occur even a few hours after the last dose of heroin. It produces a drug craving, restlessness, muscle and bone pain, insomnia, diarrhea and vomiting, cold flashes with goose bumps, kicking movements and other symptoms.
- Major withdrawal symptoms peak within two-to-three days after the last dose, and subside after a week.
- Sudden withdrawal by heavily dependent users who aren't in good health is occasionally fatal, although heroin withdrawal is considered much less dangerous than alcohol or barbiturate withdrawal.
- Opiate drug addictions are diseases of the brain and medical disorders that can be treated effectively when treatments of methadone are integrated with support services, a panel of experts at the National Institutes of Health concluded in 1998.
- Methadone blocks the effects of heroin for about 24 hours. LAAM, also a synthetic opiate medication for treating heroin addiction can block the effects of heroin for up to 72 hours.
