Marijuana and Breastfeeding: Is Smoking Marijuana During Breastfeeding Safe?


The debate on whether marijuana should be legal is one that is happening worldwide. Canada has recently legalized marijuana with strict regulations in place, and cannabis is legal in many states in the United States of America. What renders this debate to be legitimate is the medicinal value it may hold for patients going through intense pain owing to their medical condition. Marijuana does not cause any direct damage to the human body and the only reason it has been banned is owing to the fact that it may work as a gateway drug that encourages substance abuse. In areas where it has been legalized, men and women are allowed to use it cope with other medical conditions.

Can you take marijuana before or after breastfeeding?

Mothers breastfeeding their children should strictly refrain because smoking marijuana and breastfeeding simultaneously can be extremely harmful for the baby. Unlike other food and drugs, the human body takes a long time to metabolize cannabis, which is stored in the adipose tissue cells. The breast tissue in the body of a woman is made up mostly of adipose tissue, which implies that the storage unit of marijuana is also too close to the source of breast milk production and secretion. Consuming alcohol may have a simple solution where you can pump out the milk for one or two cycles to get rid of any alcohol present in breast milk. But the slow absorption of cannabis makes the combination of breastfeeding and marijuana extremely unsafe for the baby. Marijuana cannot be safely consumed by a woman breastfeeding her own child.
