Hi there, My nephew smoked cannabis at the age of 15 and went into psychosis and came out of it without medication and was perfectly fine for 3 years. Then when he reached the age of 18 he briefly experimented again with cannabis and the same symptoms happened, he came out of the psychosis again quite quickly without the aid of medication, he has promised never to do this again as he would like to train to become as an electrician, would this be wise for him to choose this career path? Kindest regards, Julia
