While Ohio's marijuana laws have loosened in recent years along with many other states across the country, the federal government still considers sale, possession and trafficking of marijuana to be illegal across the country. A growing number of states have also legalized medical marijuana, including Ohio. While dispensaries have not been established in the state, people who are eligible for medical marijuana can receive a patient identification card which can help to establish a defense in case a person is charged with a marijuana offense.
The Fourth Amendment provides protection against unreasonable search and seizure, but police officers in Ohio and around the country are permitted to conduct warrantless searches in certain situations. The U.S. Supreme Court ruled in 1925 that police could search a motor vehicle without first obtaining a search warrant provided they have probable cause to believe that evidence of criminal activity will be discovered. The nation's highest court issued another ruling on May 29 that clarified the scope of this exception.
