Lakes District Health Board says it is hard to predict whether the banning of legal highs will see an increased number of people turning to its services for help as they struggle with withdrawal.
Spokeswoman Sue Wilkie said they currently saw one to two patients a week presenting at the emergency departments, but more were being dealt with by the mental health services.
The health board's infant, child and adolescent mental health services had found the use of synthetic highs had been creating more problems for young people.
Miss Wilkie said those problems included marked exacerbation of symptoms and across different diagnoses, from psychosis to anxiety.
"Anecdotal observations by the team would suggest that use of synthetic cannabis reduces the chances of recovery and can significantly increase the risk of serious relapse of mental illness or lack of recovery."
