Cannabis Retailer Advice on Blunt, Tobacco, and Cannabis Use During Pregnancy


This recent JAMA Network Open study examines the advice pregnant individuals receive from cannabis retailers when they ask about using blunts, tobacco, or cannabis during pregnancy. Using a mystery-shopper approach across more than 500 licensed cannabis retailers in California, the researchers found wide variation, and frequent inaccuracy, in the information provided. While most retailers clearly advised against tobacco and blunt use, far fewer advised against cannabis use during pregnancy, and some actively suggested it was safe or recommended specific products or modes of use. Advice was often based on personal opinion or anecdote rather than evidence, and warnings about prenatal risk were inconsistently shared. Overall, the findings highlight a significant gap between medical guidance and the informal advice pregnant people may receive in community settings, underscoring the need for clearer public health messaging and better education about prenatal substance use.

Reflection for FASD Prevention Conversation Facilitators

This study is a helpful reminder that people are getting information about pregnancy and substance use from many places, often from sources they trust and see as non-judgmental. The advice isn’t always accurate, but it feels supportive, which matters.

For Prevention Conversation Facilitators, this reinforces the importance of leading with empathy, not correction. Many people are trying to cope with stress, anxiety, or nausea and are navigating confusing, mixed messages. Our role isn’t to shame or scare, but to gently ground conversations in evidence, acknowledge why certain choices feel appealing, and support informed decision-making. This research strengthens the case for prevention conversations that are relational, practical, and rooted in trust.
