Medical marijuana + pregnancy

Adina • I`m 24 with a 2 year old boy and another on the way. Married for 3 yrs.

A friend of mine told me about a medical cannabis card for my back issues & spine curvature. I wouldn’t take anything orally as I am expecting but there is an ointment for the back that is supposed to relax the nerves. I get my back looked at tmwr & have had this spine issue as a child so I am a little nervous to know what they tell me. Does anyone know someone who has a medical marijuana card or has gotten one while pregnant?
