Keywords:
Substance abuse, Psychotic symptom, Causal factors, ThailandAbstract
Substance abuse creates a burden of many diseases on drug users' physical and mental health. This case-control study aimed to compare the risk of developing psychotic symptoms from various substance abuse. The samples were drug users admitted to drug abuse clinics/psychiatric clinics in government hospitals aged 18 years and over across the country. A stratified multistage cluster sampling method was used to eligible 2,000 individuals. The samples were interviewed and observed by research assistants trained with researchers and healthcare professionals' history taking and physical examination. Statistical analysis utilized chi-square and multiple logistics regression.
The respondents were 94% male; most were over 24 years of age, 56% were single, 70% had graduated from junior high school and lower, and 27% unemployed. Factors affecting psychiatric symptoms consisted of 1) personal factors including marital status (single), and no occupation (unemployment, housework, no income), 2) drug factors such as yaba (methamphetamine tablet), ice (methamphetamine crystal), marijuana, heroin, volatile substances, ecstasy, ketamine, non-prescribed medicines, 3) duration of drug use (more than 10 years), and 4) regularly used (more than 20 days in 1 month), and frequently used (more than once a day). These factors statistically significantly increased 1-7 times the risk of developing psychiatric symptoms.
