Hello. Very Good evening. As per your history or question asked, first of all Mirtazipine is a antidepressant drug but the daily maximum dosage of Mirtazipine is 15 mg should be taken at bedtime. Next no doctor prescribes you Cap. Tramadol which is a narcotic Pain killer and should be avoided in person taking Mirtazipine. And it depends for which severe Pain, the tramadol is being prescribed. Tramadol,  if taken on regular basis can proved to be addictive & also a high end Pain killer given in intravenous form in Emergency room. Lanzoprazole is taken for Gastritis and Acid peptic Disorder for a given course, but can be taken on and off. Consumption of cannabis is illegal and should not be used by patients taking Mirtazipine or Tramadol. Its like playing with fire. For more information kindly come to practo chat. Take care and have a hasty recovery. Bye.
