Not sure why you're joking, cannabis use absolutely gave me schizoid symptoms like ideas of reference, etc. This is an actual thing that can happen for some people.
Exactly cannabis abuse and schizophrenia often go hand in hand. There is also some evidence that cannabis use can trigger the condition, esp. in people with a predisposition.
I think you might mean schizotypal symptoms. Schizoid personality disorder is considered "on the spectrum" with schizophrenia but has very little similarity to it other than social withdrawal.
