As of May 2017, however, you will find the addition of "Marihuana Extract" in the Texas Register [PDF] (not the Health and Safety Code) by the order [PDF] of the Commissioner of the Department of State Health Services.

While in all of these states recreational marijuana remains illegal, Connecticut, Delaware, Illinois, Maryland, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New York, North Carolina, Ohio and Rhode Island have all decriminalized the drug. In these states, having smaller amounts of marijuana on you won't lead to an arrest or a criminal record. The maximum amount you're allowed to have on your person will vary by state.
