Recreational use of cannabis (commonly known as marijuana) became legal in Illinois on January 1, 2020. Recreational use and possession of cannabis is only legal for adults ages 21 and older.
Tetrahydrocannabinol (THC), the psychoactive component in marijuana, impacts normal brain function and development, even in adults. The THC component of today’s marijuana is three times what it was 25 years ago. Like tobacco, smoking marijuana can harm your lungs.
Over-consumption of marijuana can result in negative, harmful side effects including hallucinations and paranoia. Driving under the influence of marijuana is illegal and can increase your risk of getting into an accident. Cannabis use can also lead to addiction. Research suggests that the earlier in life you begin using it, the greater the risk for addiction.
There is no safe amount of cannabis while pregnant or breastfeeding, regardless of how you consume it. THC can be transferred to your baby through your placenta or breast milk.
