My experience with the substance is similar to yours. I’ve started again occasionally and see that the experience differs depending on the strain. I do get paranoia that wears off; there were times where I’ve experience schizophrenia like symptoms; where reality seems off or my perception of it changes temporarily until it wears off. Hopefully I don’t have early onset of the disorder.

Regarding your friends, is it possible that the behavior you are seeing is when they are under the influence and not during sober?
