(CNN) - Women may be getting mixed messages about cannabis use during pregnancy.
A new study shows many dispensary employees in Colorado encourage moms-to-be to use their products for morning sickness, however this advice clashes with doctors' warnings about the potential harms of marijuana use during pregnancy.
The study used the mystery caller approach, with the caller saying something like this:
"Hi, I'm eight weeks pregnant and feeling really nauseated. Are there any products that are recommended for morning sickness?"
Sixty-nine percent of the dispensaries contacted recommended cannabis to treat nausea in the first trimester.
"It was surprising and concerning to us because there are (sic) data that would suggest that cannabis can be harmful to the developing fetus," said Dr. Torri, a high-risk Obstetrician.
When researchers asked what product was recommended, one dispensary employee replied:
"Technically with you being pregnant, I do not think you are supposed to be consuming that, but if I were to suggest something, I suggest something high in THC."
When a researcher asked another employee if she should check with a health care provider first, the employee responded: "I think that would be a smart choice. Try for someone that is liberal or pro-cannabis."
"We have a lot of rules, but one of the rules we do not have is to be a doctor," said Kristi Kelly with Marijuana Industry Group
Kelly said the study points to the need for more training.
"It is very important that the dispensary employees clarify that they are not medical professionals and that they redirect either that patient or customer to also have conversation with their health care professional," she said.
"Personally, I wouldn't recommend that they consume marijuana, because by law on our labels, we do have to say that there are health risks associated with the consumption of marijuana and pregnancy," said Amanda Talamantes, with The Little Green Pharmacy.
