I have been smoking weed and THC Vapes every day, all day for the last 10 years. I've recently learned that this has caused my brain to go into a state of psychosis which has caused my brain to build "walls". After a long realization and breakthrough with my therapist. I threw all of my paraphernalia into the dumpster. I am currently over 5 hours sober. How can I teach my brain this is a dependency and not a need? I am looking to connect with others who have gone through the same.
