Certain medications, including opiates and cannabis, can influence breast tissue and lactation processes in various ways. Galactorrhea, which is the inappropriate production of milk from the breast, can occur due to the effects of these substances. This phenomenon is primarily linked to their action on hormonal pathways, where they may increase prolactin levels, a hormone that plays a significant role in lactation.

Increased prolactin levels can lead to unexpected lactation in individuals who are not currently breastfeeding or pregnant. This effect is especially notable with certain medications that alter the endocrine system, emphasizing the potential for these substances to interfere with normal breast tissue physiology. Understanding the role of these substances in lactation and breast tissue responsiveness enhances our comprehension of how various medications impact not only breastfeeding but also overall breast health.
