Marijuana’s potency has increased over the past few decades. The majority of products have THC levels higher than 15%.¹ There is growing scientific evidence that heavy, regular use of cannabis products and marijuana that begins during the teen years may lower a person’s IQ. It can also increase the risk for several mental health problems including depression, anxiety, and psychosis.²
In both youth and adults, the perceptions around the risk of marijuana use has decreased dramatically. This is true not only in Connecticut but all over the United States. Some of this shift is in response to changes in social policies and laws.
