The Rhode Island Council for Child and Adolescent Psychiatry, or RICCAP, is warning against legalizing recreational marijuana. The organization has issued a statement about the drug’s impact on young people.

With two New England states, Massachusetts and Maine, set to vote on recreational marijuana next week, RICCAP cites the growing interest in legalizing marijuana as the impetus for putting out a statement. 

The group says its members have seen an increase in marijuana-related hospitalizations among young people. They say one in six young marijuana users will get addicted, and Rhode Island doesn’t have enough treatment programs for adolescents.

What’s more, RICCAP’s Doctor Elizabeth Lowenhaupt says adolescents are particularly vulnerable to marijuana’s effects.

“The people who have used marijuana as adolescents are more likely to develop psychotic illness like schizophrenia down the line than their peers who haven’t,” said Lowenhaupt.

Lowenhaupt says the data isn’t clear on whether legalizing marijuana increases use of the drug among adolescents. But debate is likely to intensify in Rhode Island, especially if neighboring states choose to legalize recreational marijuana.

Both Rhode Island and Massachusetts are among a growing number of states to allow medicinal use of pot, and tthe two states have already decriminalized possession of small amounts of marijuana.
