[Drug use and treatment misuse: Key points on polydrug use]

Area of Science:

• Addiction Medicine
• Psychopharmacology
• Public Health

Background:

• Problematic psychoactive drug use encompasses a wide range of substances, including legal, prescription, and illicit drugs.
• Polysubstance drug use represents an expanding trend, posing complex epidemiological challenges and requiring further research into user patterns.
• Understanding specific drug combinations and associated user clusters is crucial for identifying medical and social risks.

Purpose of the Study:

• To analyze patterns in polysubstance drug use.
• To identify user clusters associated with specific medical and social risks.
• To inform management and prevention strategies for polysubstance users.

Main Methods:

• Epidemiological analysis of polysubstance drug use patterns.
• Identification of user clusters based on drug combinations.
• Assessment of medical and social risks associated with polysubstance use.

Main Results:

• Certain patterns of drug combinations can be identified, forming user clusters.
• These clusters are associated with specific medical and social risks.
• Current therapeutic tools for polysubstance use are often limited to individual substance treatments.

Conclusions:

• Managing polysubstance users requires assessing individual drug use, inter-drug connections, and patient expectations.
• Complications, psychiatric, and somatic comorbidities must be considered in treatment.
• Prevention strategies need to adapt to identified use clusters, gender, and risks like chronic pain and opioid dependency.
