A new study finds people who become addicted to drugs later in life are more likely to relapse during treatment, compared with those whose addictions started earlier. For every year increase in the age of starting to abuse opioids, there is a 10 percent increase in relapse, according to Science Daily.
The study of people being treated with methadone for their opioid use disorder found those who injected drugs were more than twice as likely to relapse by using opioids while on treatment, compared with those who did not inject drugs.
Use of benzodiazepines also increased the risk of relapse, the study found. For every day of benzodiazepine use in the previous month, the researchers found a 7 percent increase in relapse.
