[|Human|] Can marijuana and lactulose cause a side affect when used together Hi, my father in law is dying of sclerosis of the liver he had been sober for 10 months he is taking lactulose for liver disease and constipation . Due to the liver disease he is unable to take any pain med so he smokes marijuana, can the marijuana and lactulose together cause a bad side affect?
[|AI|]  Hello;welcome to Chat Doctor Lactulose is a locally acting medicine and has its effect on the intestines and there is hardly any chance of interaction with other medicines or even marijuana for that matter. Although it is not necessary to say that marijuana is harmful to health but since he has found a way to relieve his pain without the use of painkiller, and he has terminal illness I personally will not comment on that.Let's just hope and pray for the best. Thanks
