New Illinois Marijuana Law Reduces Possibility of Getting DUI After Smoking Weed

In the past, if you were caught driving in Illinois with even a trace of marijuana in your blood, you could be charged with a DUI, regardless of whether or not your driving skills were impaired.

Under the new Illinois law, if you are caught driving while under the influence of marijuana, police won’t charge you with a DUI unless 5 nanograms or more of THC in your blood (or 10 nanograms or more in your saliva) is detected.

Illinois Municipalities Can Increase the Penalty for Marijuana Possession

Cities and towns throughout Illinois can increase the fine amounts for marijuana possession, or they can add additional penalties, such as a requirement that defendants complete a drug education class in addition to paying the fine.
