"Ohio law prohibits the over-the-counter purchase of a consumer product containing a total amount of base pseudoephedrine or base ephedrine that exceeds either three and six tenths grams in a single day or nine grams within any period of thirty consecutive days. If, without a valid prescription, you purchase a consumer product containing pseudoephedrine or ephedrine, you are required to sign a log book that may be accessible to law enforcement officers and provide a government-issued identification card to verify your identity. Except in limited circumstances, the purchase of more than the permissible amount of a consumer product containing pseudoephedrine or ephedrine, and the purchase by any individual under eighteen years of age of a consumer product containing pseudoephedrine or ephedrine, are subject to criminal prosecution or delinquency proceedings in accordance with Ohio law. Also, the provision of false information concerning an individual's name, age, or other identification for the purpose of acquiring a consumer product containing pseudoephedrine or ephedrine is subject to criminal prosecution or delinquency proceedings in accordance with Ohio law."
