Categories of psychoactive drugs Stimulants, depressants, opioids, hallucinogens, and cannabis Psychoactive drugs are substances that alter brain function, leading to temporary changes in perception, mood, consciousness, and behavior Major categories include: Stimulants (cocaine, amphetamines) increase alertness, attention, and energy by enhancing the activity of dopamine and norepinephrine neurotransmitter systems in the brain Depressants (alcohol, benzodiazepines, barbiturates) reduce anxiety, induce sleep, and slow down brain activity by increasing the effects of the neurotransmitter GABA and reducing excitatory neurotransmission Opioids (heroin, morphine, prescription painkillers) produce feelings of euphoria and pain relief by activating opioid receptors in the brain, primarily in regions involved in reward processing and pain modulation Hallucinogens (LSD, psilocybin) cause altered perceptions, thoughts, and emotions by acting on serotonin receptors in the brain, particularly the 5-HT2A receptor subtype Cannabis (marijuana, synthetic cannabinoids) produces relaxation, altered sensory experiences, and impaired memory by activating cannabinoid receptors (CB1 and CB2) in the brain Mechanisms of psychoactive drugs Interactions with neurotransmitter systems Psychoactive drugs exert their effects by interacting with specific neurotransmitter systems in the brain Mimic the actions of endogenous neurotransmitters Block neurotransmitter reuptake Alter neurotransmitter production or release Stimulants (cocaine, amphetamines) increase dopamine and norepinephrine levels by: Blocking their reuptake transporters (DAT and NET) Promoting their release from presynaptic terminals Leads to enhanced signaling in reward and arousal pathways Depressants (alcohol, benzodiazepines) enhance the activity of the inhibitory neurotransmitter GABA by: Binding to GABA receptors (particularly GABA-A) Increasing their responsiveness to GABA Results in reduced neuronal excitability and anxiety Opioids bind to and activate opioid receptors (mu, delta, and kappa) in the brain Mimic the actions of endogenous opioid peptides (endorphins, enkephalins) Leads to reduced pain perception and increased dopamine release in reward circuits Hallucinogens (LSD, psilocybin) act as agonists at serotonin 5-HT2A receptors Leads to altered sensory processing, perceptual changes, and mystical-type experiences Cannabis compounds (THC) bind to and activate cannabinoid receptors (CB1 and CB2) Modulates the release of various neurotransmitters (GABA, glutamate, dopamine) Results in altered cognition, memory, and mood Effects of drugs on brain Short-term effects on brain function Acute changes in neurotransmitter levels, receptor activation, and alterations in neuronal firing patterns Leads to the desired psychological and behavioral effects Long-term adaptations in brain structure and function Chronic use of psychoactive drugs can lead to long-lasting changes: Receptor density Neurotransmitter production and release Synaptic plasticity Stimulant use can cause: Dopamine depletion Reduced dopamine receptor availability in the brain's reward system Contributes to anhedonia, craving, and addiction Long-term alcohol use can result in: Neurodegeneration, particularly in the frontal lobes and hippocampus Impairments in executive function, memory, and emotional regulation Chronic opioid use can lead to adaptations in the brain's pain and reward systems Reduced sensitivity to natural rewards Increased sensitivity to pain (hyperalgesia) Contributes to the development of tolerance and dependence Hallucinogen use, particularly chronic use, may cause: Persistent perceptual disturbances (HPPD) Alterations in brain network connectivity Long-term effects are not well understood Regular cannabis use, especially when initiated during adolescence, can: Impair cognitive function, particularly memory and attention Increase the risk of developing psychiatric disorders in vulnerable individuals Therapeutic uses vs risks Potential therapeutic applications for mental health disorders Some psychoactive drugs, when used under medical supervision, can be effective treatments for various mental health disorders Depression Anxiety PTSD Substance use disorders Stimulants (methylphenidate, amphetamines) are used to treat attention-deficit/hyperactivity disorder (ADHD) Enhance dopamine and norepinephrine signaling in the prefrontal cortex Improve attention and reduce impulsivity Antidepressants (SSRIs, TCAs) are used to treat depression and anxiety disorders Increase the availability of serotonin and/or norepinephrine in the brain Benzodiazepines are prescribed for short-term treatment of anxiety disorders and insomnia Rapid anxiolytic and sedative effects mediated by GABA-A receptor activation Opioid agonists (methadone, buprenorphine) are used in medication-assisted treatment (MAT) for opioid use disorder Reduce withdrawal symptoms and craving Block the effects of illicit opioids Ketamine, an NMDA receptor antagonist, has shown rapid antidepressant effects in treatment-resistant depression Long-term safety and efficacy remain under investigation Psychedelic-assisted psychotherapy (psilocybin, MDMA) is being explored as a potential treatment for: Depression Anxiety PTSD Substance use disorders Promising initial results Risks associated with the use of psychoactive drugs The use of psychoactive drugs in treating mental health disorders also carries risks: Side effects Drug interactions Dependence Potential for abuse Necessitates careful monitoring and individualized treatment plans
Sensitivity analyses (reported in the Supplementary File) were conducted in four additional populations (defined in the Supplementary File) to test the robustness of the ITT results to different patterns and levels of e-diary completion
