Polydrug Use

Polydrug Use Defined Polydrug use refers to: “. . . the concurrent use of multiple drugs, or the combining of drugs. It can occur in a range of patterns and for a variety of reasons, and may or may not involve drug dependence. ” Swan & Ritter (2001, p. 1) Polydrug Use

Polydrug Use • Becomes a concern in terms of its relative risk • Generally associated with hazardous or harmful use of > 1 drug • Appears to be ‘the norm’ amongst many drugusing groups – many of whom rarely limit use to one drug, or – who use a primary drug along with a range of other drugs • Is highly prevalent among clients of drug treatment services. Polydrug Use

Patterns of Polydrug Use Think about: context, patterns of use and dependence Common patterns of use include: – using from multiple drug classes, but there is no evidence of dependence on any one class of drug – dependence on one drug class, but use of other drugs – dependence on several drugs or classes of drugs. Polydrug Use

The Nature of Polydrug Use Polydrug use depends on a range of factors: – demographic and social – availability and price – desired effect and outcome of use – previous experiences (institutionalisation or previous medical treatment appears to influence polydrug use behaviours). Polydrug Use

Reasons for Polydrug Use • To enhance effects of other drugs • To counteract effects of other drugs • To provide a substitute for a preferred but unavailable drug • To conform to normative ways of using drugs • To counteract the unpleasant effects of drugs from different classes • To self-manage the withdrawal from one drug by using another.

Service Provision and Polydrug Use • Engage into treatment • Ensure effective collaboration • Use Harm Reduction strategies – prevention BBV, reduce use, crisis intervention • Multimodal treatment and cross referral • Regular review. Polydrug Use

Polydrug Assessment Issues (1) • Conduct a systematic assessment of each drug class – episodic use, time frame of at least 4 weeks, changing patterns of use with changing availability, dependence (>1 drug? ). Include tobacco ! • Examine relationship between use of various drugs – Is use of one drug related to the absence or use of another? Any drug free periods? Use of one drug to modify withdrawal from another? • Identify drug use patterns, dependence and high-risk using practices – use of drugs from different classes +/- dependence on one or all. Polydrug Use

Polydrug Assessment Issues (2) Try to gain a sense of: • patient’s reasons for choosing to use particular drugs • their multiple problems or concerns • how their drug use and lifestyle affects them (include both positive and negative aspects) • potential for withdrawal. Polydrug Use

Screening • WHO is developing a composite polydrug screening instrument: ASSIST: Alcohol, Smoking & Substance Involvement Screening Tool • To be used in primary health care settings to help GPs decide whether the patient will benefit most from: – information – brief intervention, or – referral to specialised treatment. Polydrug Use

Other Assessment Issues • Allow adequate time (more time is needed than for a single drug assessment) • Obtain corroborating information – e. g. , friends / family, with consent • Delay assessment if intoxicated – apply harm reduction principles • Consider your role and the practice staff in the management of people with complex polydrug use issues. Polydrug Use

Key Issues in Treatment • Harm mimimisation strategies a priority • Opportunistic brief interventions are often all that can be delivered • Long-term treatment perspective is required – few people abandon all drug use in the short term • Numbers of drugs used tend to with age • Patients may only be interested in dealing with most immediate/problematic issues. Polydrug Use

GPs and Management (1) • Polydrug issues are complex, patients often present in crisis. Clarify your role • Consider a ‘shared care’ approach: – AOD specialists (including mental health services) – relevant local health and welfare agencies – crisis intervention services – families and other peer support groups (esp. useful with young people). Polydrug Use

GPs and Management (2) • Develop ongoing therapeutic relationship (BI, counselling etc. ); encourage return despite possible frequent non-attendance • With patient, identify which (most harmful) drug to tackle first for stabilisation or withdrawal • Polydrug withdrawal is complex – work with (or refer to) specialists • Ensure contact and liaison with other AOD services. Polydrug Use

Who is Suitable for Counselling? • Counselling is suitable for those who: – self-identify as polydrug users – are subject to court orders – are pressured into treatment by employers, family or friends • Counselling is not suitable for those who: – are actively psychotic – have significant cognitive impairment or intellectual impairment – are grossly intoxicated.

A Final Comment If the young polydrug user can be kept alive, and free of disease, there is a natural tendency towards eventually moderating or giving up drug use. Treatment may provide ‘a nudge along the natural pathway of recovery’. Polydrug Use
