Kicking the habit
Kicking a heroin habit can be tough. Withdrawal symptoms start between 6 and 24 hours after the last dose and are worst after 2-4 days. They usually last for about a week and include cravings, depression, diarrhoea, increased heart rate, vomiting and loss of appetite.
Some mental health symptoms can last for years after the last dose, such as depression, anxiety, insomnia and continued cravings.
There are many different ways to treat a heroin addiction. Counselling and support groups are common approaches. Some people recommend methadone, which is a prescription drug used as a replacement for heroin. Find out about methadone on the Druginfo website.
