Computer-delivered Screening & Brief Intervention for Marijuana Use in Pregnancy

A single 20 minute interactive computer-delivered intervention designed to promote motivation to change prenatal marijuana use, without presuming the participant to be currently using marijuana while pregnant.

Group text messaging software from Trumpia, Inc. will be used to create the tailored text messages that will be sent to participants assigned to this intervention. Text messages will sent after the initial study participation visit until childbirth or participant opts out of receiving them.
