No. Infusing cannabis into coconut oil works great when looking for a way to ingest cannabis. Since the essential fatty acids in the coconut oil are easily processed by the liver, and THC is also processed by the liver when eaten, the infused oil gives the cannabinoids a great entry into the liver where it can be processed into the metabolite called 11-hydroxy-THC.
Once the cannabinoids are infused into the coconut oil, you will be able to gain the benefits of both the medical marijuana strain you have chosen to use, as well as the natural health and immune benefits of the coconut oil itself.
CBD has also proven effective at protecting the liver from steatosis caused by alcohol drinking by preventing an increase in oxidative stress and the autophagy induced by alcohol, thus protecting the liver from progressive damage.
I suggest that you discuss the use of cannabis with with your primary care provider since he/she is aware of your medical history and overall health.
