Sorry to hear about one of your children devloping schizophrenia. But as you say, if he/she was smoking it like cigarettes then maybe something should have been done earlier? And you could argue perfectly logically, that the reason weed is getting stronger is because it is illegal. Take Alcohol Prohibition as Exhibit 1. And I know if my child (or anyone for that matter) was drinking vodka like beer, they would be headed for big trouble. I would intervene immediately and put an end to it. But I wouldnt blame the vodka and demand that people who make it are put in jail.
