A long-term study from Denmark, explored a number psychological factors that may or may not have adverse outcomes on the children.
The Danish study determined that parental factors most likely to create either violent or suicidal tendencies in adulthood are 1) parents who used marijuana; 2) having parents who are sociopaths or 3) having parents who attempt suicide. In other words, marijuana abuse is far more serious in predicting adverse behavioral outcomes than other parental mental health conditions such as bipolar disorder and alcoholism.
