Chronic marijuana use and higher dosages are found to correlate with a greater incidence of psychosis and schizophrenia. This point is particularly significant due to the increases in drug potency over the last two decades. While the average potency has risen from 3% THC (tetrahydrocannabinol—the intoxicating ingredient in marijuana) a couple of decades ago to 9% now, there are some samples of weed that measure as high as 25%. These premium strains are normally grown hydroponically, are often smuggled in from Canada and demand a higher price than commercial-grade marijuana from Mexico.
Heavy abusers of marijuana were found to suffer damage to social life, work or career status and cognitive ability. Schoolwork and the achievement of goals were also found to suffer.
