I have found that cannabis helps with controlling my tics. Tics include voicing out phrases, arm jerks, head jerks and grimacing. It is also being used to control schizophrenic symptoms including daytime nightmares, obsessing on problems magnified by my imagination. I am able to positively dream of better outcomes with much emotional relief. My psych dr and I discuss the necessity to maintain therapeutic levels once learned and to be consistent with this herbal medicine. There are dozens of research studies supporting cannabis for schizophrenia. The science is there and increased understanding will come once full legalization of medical use takes place across the nation.
