a smoking and drinking area. In this area no food or drink can be served, no food can be consumed, no entertainment can be offered and there must be no gaming machines provided. A "buffer", which can be either a 2-metre-wide area or a 2.1-metre-high screen that is impervious to smoke, must be on the area's perimeter wherever it is adjacent to other parts of the outdoor area usually accessed by patrons. Premises that choose to have such an area must have a smoking management plan for the premises that complies with legislative requirements. For all other outdoor eating or drinking places, smoking has been prohibited since 1 July 2006. Since 1 January 2010, the Queensland Government banned smoking in cars where children under the age of 16 are present. In 2014, Queensland banned tobacco in correctional facilities, the second state to do so, but high rates of smoking relapse among people released from prison have led to debate around the effectiveness of this ban in promoting long-term cessation. Some prisoners in Queensland are getting around the prison smoking bans by creating and smoking "teabacco", which is nicotine patches or lozenges mixed with tea leaves, and rolled up in Bible paper. A forensic analysis of teabacco made from nicotine lozenges identified some potentially toxic compounds, but concluded that teabacco made from nicotine lozenges may be less harmful than traditional tobacco cigarettes. South Australia South Australia banned smoking in enclosed public place on 1 November 2007. Under the SA Tobacco Products Regulation Act 1997, a place or area is only "enclosed" if it is fully enclosed or is at least partially covered by a ceiling and has walls such that the total area of the ceiling and wall surfaces exceeds 70 per cent of the total notional ceiling and wall area. It is illegal to smoke in cars while children (under 16) are passengers. Since April 2012, smoking is not allowed beneath covered public transport waiting areas, including bus, tram, train and taxi shelters. South Australia banned smoking inside prison cells starting in January 2015. Smoking in public outdoor dining areas has been banned in South Australia since July 2016 (the second-to-last state to do so).
