How do synthetic drugs in vape liquids affect brain function and decision-making?

Question

Accepted Answer

Synthetic drugs in vape liquids can disrupt executive brain functions, leading to poorer decision-making and risky behaviour

Synthetic drugs and psychoactive substances mixed into vape liquids can impair brain function, especially the brain areas responsible for executive functions. Executive functions normally help a person think rationally, assess risks, and weigh consequences before acting. When these functions are disrupted, people become more likely to act on emotional impulses or immediate stimulation rather than considering outcomes.
Executive functions are tied to rational thinking and risk assessment
The substances can disrupt the part of the brain responsible for executive functions, which include the ability to think rationally, assess risks, and consider the consequences of actions. Under normal circumstances, these functions allow someone to pause before acting and judge whether a decision is safe. With impairment, rational evaluation is weakened, and behaviour becomes less guided by careful assessment.
Impaired self-control increases impulsive choices and dangerous actions
When executive functions are affected, individuals are more likely to act based on emotional impulses or immediate stimulation without factoring in consequences. The reported outcomes include situations where users may drive, harm themselves, get involved in fights, or make decisions that endanger themselves and others. Such behaviour is described as potentially reflecting drug-related impairment in judgement, self-control, and decision-making rather than a person’s true character.
Hallucinations and delusions can distort reality and trigger uncontrolled reactions
Psychoactive substances can also lead to hallucinations or delusions that distort a person’s perception of reality. This can cause someone to believe false things or react to threats that do not actually exist. Those distorted perceptions may then contribute to acting uncontrollably.
Adolescents may be more vulnerable because their brains are still developing
Adolescents’ developing brains can show more pronounced disruption to self-control functions compared with adults. The combination of an immature brain and the effects of synthetic drugs can further increase the likelihood of decisions that put adolescents at risk. This is one reason experts highlight the particular danger of synthetic drugs delivered through vaping among youths.
