- Strengths
- Withdrawal symptoms support the biological viewpoint that the brain is relying on the drug to function normally, as symptoms are of a sever deficit of the relevant neurotransmitter
- There is a strong positive correlation between diagnosis of psychosis and heavy use of cocaine and/or amphetamines, suggesting that the drugs are including psychosis
- Self- report evidence from drug users show the development of psychological need correlates positively with physiological measurements of dependency
- Weaknesses
- There are large individual differences in whether a person becomes an addict. According to the biological explanation everyone is at risk of misuse developing yet, in the case of a common drug such as alcohol, for example . the majority of adults i Britain use the drug but only a minority misuse it.
- Cultural norms and peer group influences play a major role in the likelihood of misuse occurring, as well as decisions about the drug of choice
- If biological factors were what determined the amount required for a fix, overdosing because of context dependency would not occur.
- Over dosing on a normal sized fix of heroin while in the police custody is believed to be cause by the mismatch between the fix and context cues
- Operant conditioning is also important in both starting and maintaining drug taking. Initially people usually start taking drugs because they enjoy the effect
- Over dosing on a normal sized fix of heroin while in the police custody is believed to be cause by the mismatch between the fix and context cues
