Child development and parenting capacity
Although parents have needs in their own right, here we are concerned with the impact of parental substance use on the child.

Cleaver et al. (1999) reviewed the factors that place children at more or less vulnerable to the behaviours that result from their parents' problems. Their review was confined to the findings from research. This means that factors identified from clinical and professional practice were omitted.
In the following extract from Cleaver et al. (1999), only the effects of parental drug and alcohol use on the child are included. They point out that it can be difficult at times to distinguish the effects of substance use from the effects of mental health (e.g. where there is co-morbidity or a dual diagnosis) and domestic violence (e.g. where violent behaviour stems from excessive alcohol use).
It is recommended that those directly concerned with addressing children in need and child protection, should obtain Cleaver et al. (1999):

The edited extract below is included for educational urposes, and as a 'taster' to go out and buy the book.
The age ranges have been divided in the effects upon:
Pre-birth - 2 years old
Key problems/risks
Health
- Foetal damage brought about by intake of harmful substances. The impact will depend on which substances are taken, the stage of the pregnancy when substances are ingested, and the route, amount and duration of substance use. Moderate regular alcohol or drug use may be less harmful than binge alcohol or drug use, which can place the foetus at risk from sudden withdrawal.
- Spontaneous abortion, premature birth and low birth weight, and still birth.
- Babies suffering withdrawal symptoms from foetal dependency may be difficult to manage.
- Drugs and alcohol use may have caused neurological and physical damage to the baby.
- Babies may be neglected physically and emotionally to the detriment of their health.
- Living in an impoverished physical environment may exacerbate the child's health problems.
Emotional and Behavioural Development
- A lack of commitment and increased unhappiness, tension and irritability in parents may result in inappropriate responses which lead to faulty attachment.
- Different strangers caring for children at different times can lead to insecure attachments.
Identity
- Children may fail to develop a positive identity because they are rejected and are uncertain of who they are.
Protective factors
- Good regular antenatal care.
- Adequate nutrition, financial support and housing for the expectant mother.
- The avoidance of viruses, unnecessary medication, smoking and severe stress.

- Inconsistent parenting may damage children's attachment.
- When parent's behaviour is unpredictable and frightening children may display emotional symptoms similar to those of post-traumatic stress disorder

Other
- Children may have their physical needs neglected, e.g. they may be unfed or unwashed.
