Someone please help I've been worrying about this situation! My family has a history of schizophrenia (grandmother) and bipolar (mother). My mom told me herself that she feels weed caused her to have a mental breakdown which happend twice within the last 6-7 months since she smoked so much when she was younger and she smoked still as an adult. I'm 16 and smoke daily and I'm terrified I will get any of these mental illnesses because I have witnessed my mom and grandmother go through it, and it is terrifying. Please someone tell me your input on if you feel smoking at an early age, could cause mental illness? Or if you have a history of mental illness in your family, are you still completely healthy?
