“…Nonetheless, epidemiological and clinical studies on the foetal impact of alcohol, drug, and tobacco use during pregnancy are plentiful. These studies usually focus on outcomes such as birth weight, birth deficiencies, as well as long-term effects on the child's health, social and psychological development (Bauer et al, 2011;Della Grotta et al, 2010;Higgins, Clough, & Wallerstedt, 1995;Hjerkinn, Rosvold, & Lindbaek, 2009;Holmila, Raitasalo, & Kosola, 2013;Kissin, Svikis, Morgan, & Haug, 2001;Moe, 2002;Shankaran et al, 2007;Walton-Moss, McIntosh, Conrad, & Kiefer, 2009). Smaller clinical samples and register-based population studies have also been used to study substance abuse in connection with pregnancy or among mothers of small children (Holmila et al, 2013;Kahila, Gissler, Sarkola, Autti-Ramo, & Halmesmaki, 2010;Raitasalo, Holmila, Autti-Ramo, Martikainen, et al, 2015;Raitasalo, Holmila, Autti-Ramo, Notkola, & Tapanainen, 2015;Sarkola, Gissler, Kahila, Autti-Ramo, & Halmesmaki, 2012).…”
