Substance Misuse CAMHS

1. Substance Misuse CAMHS Background etc Alcohol and drugs....rising evidence of neurobiological and social vulnerability, versus purely ‘behavioural and morally objectionable’ Brain circuitry and reward centres, euphoria with drugs focussed around brain areas involved in natural reward (food, sex and imbibing fluid)

2. Substance Misuse CAMHS Background etc Tolerance (delayed and rapid) and sensitisation (cocaine seizures and psychosis) Withdrawal manifestations of established homeostatic changes in the brain caused by chronic use. Potentially lethal in alcohol and hypnotics. The use of long acting substances to manage withdrawal. Dependence. All those which cause dependence share action on reward centres. Specifically DA in the nucleus accumbens. DA crucial but also 5HT, Opioids, GABA and Glutamate
