A close family member of mine was smoking a lot of weed. I didn't think it was too much of a
prob as many of us have toked in our lives at some point.
But the stuff people smoke now is much stronger stuff. I wouldn't go near the stuff now.
His behaviour became more erratic. It was definitely due to the drugs which seemed to bring on paranoia and hearing voices.
He was sectioned.
He has to take his medication now. It helps him, but he is still a little unpredictable and he does seem to be of normal nature.
BBB, its not something easy to bear. Especially as its your father. I wish you well. I also say stick with him through this time and make sure he takes his medication.
