I'm sorry to say that some personal friends of mine inherited their mother's bipolar schizophrenia. in their mid-20s to early-30s, both showed serious symptoms.
In their case I will personally testify that schizophrenia is the single health condition I would plead with you to use extreme caution & experiment with a safe environment & trusted friend. my gut tells me to tell you to run away from weed as fast as possible, but i am not an expert, just a considerate guy with some first-hand experience, suggesting extra caution.
my (friends) should avoid THC like ebola, i'm afraid.
i lived with them for over a year & had to leave because of the problems that were starting. one was gun-nut alcoholic & little brother was clinical enough to throw a spear at a sherrif.
not a laughing matter, i'm just an ass that has to joke my way through life.
