About 17.7 percent reported using cannabis for three or fewer years, 16.2 percent for four to five years and 14.3 percent for six or more years.
Those who had six or more years of use were twice as likely as those who never used cannabis to develop a psychosis, such as schizophrenia, and four times as likely to get high scores in clinical tests of delusion.

Of the 1,272 subjects who had never used marijuana, 26 (2 percent) were diagnosed with psychosis. Of the 322 who had used it for six years or more, 12 (3.7 percent) were diagnosed with the illness.
If I'm a researcher is 1.7% even statistically significant? I think you could make a statement like that for just about anything we consume, for example, aspirin.

Your probably right, I am not sure how they did this or why but I found the numbers pretty low too.
