Although cannabis is now legal in Ohio for medicinal use, a panel for the state’s Supreme Court said recently that lawyers are not permitted to provide legal services for those groups and individuals interested in getting into the business of medical marijuana because cultivation, sale and use of herb still remains illegal in the eyes of the federal government.The board’s advisory opinion indicates that, “a lawyer may not advise a client to engage in conduct that violates federal law, or assist in such conduct, even if the conduct is authorized by state law.”
