Items used for injecting illegal drugs are classified as drug paraphernalia. It is illegal to sell, deliver for commercial consideration, or possess with intent to use drug paraphernalia.
Penalties are stiffer for delivery to a minor or delivery to a pregnant woman.
Any store or place that sells or delivers for commercial consideration drug paraphernalia is declared a public nuisance. The Illinois Code contains a section called the Hypodermic Syringes and Needles Act. However, the web address for that section is not working correctly, and at this time, access to the Act is not possible. The webmaster at the Illinois Statutes website has been notified, and corrections will hopefully be made soon.
