“…Males typically have higher SS scores than females (Zuckerman et al, 1978), but the link between SS and drug use is found in both sexes, in general. The link between high SS and drug abuse has been found with many drugs including nicotine, alcohol, opioids, hallucinogens, and stimulants (Pedersen et al, 1989; Bobes et al, 2002). Several studies have established that HSs are more sensitive to the subjective, reinforcing and/or physiological effects of drugs: the drugs studied included alcohol (de Wit et al, 1987; Fillmore et al, 2009), amphetamines (Hutchison et al, 1999; Kelly et al, 2006, 2009; Stoops et al, 2007), methylphenidate (Chait, 1994), benzodiazepines (Kelly et al, 2009), and nicotine (Perkins et al, 2000).…”
