6.1 What is behind psychostimulants\u2019 stimulating effects?<\/strong><\/p>\n\n\n\n

Psychostimulants are drugs that activate the central nervous system, making you feel more alert, energetic, and even excited.<\/p>\n<\/div>\n<\/div>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

They work by increasing the levels of key brain chemicals<\/strong> like dopamine, norepinephrine, serotonin. This rise in activity stimulates the brain\u2019s reward and arousal pathways<\/strong>, enhancing feelings of pleasure and wakefulness.

Drugs like cocaine and methamphetamine<\/strong> (MAMPH) specifically target dopamine and norepinephrine transporters<\/strong>. They cause a rapid buildup of these chemicals in the brain, intensifying their effects and leading to a powerful, short-term high.<\/p>\n\n\n<\/div><\/div><\/div><\/div>

Schizophrenia and Stimulant Use: challenges and consequences<\/strong><\/p>\n\n\n\n

Recent studies on the overlap between schizophrenia and stimulant use disorders reveal significant diagnostic and treatment challenges<\/strong>.<\/p>\n\n\n\n

Stimulants like methamphetamine and amphetamines<\/strong> can worsen psychotic symptoms<\/strong>, making it harder to distinguish between schizophrenia itself and drug-induced psychosis.

For individuals with schizophrenia, stimulant use increases the risk of hospitalization and premature death<\/strong>. This highlights the need for specialized treatment approaches that address both disorders simultaneously<\/strong>.<\/p>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

How do psychostimulants create addiction?<\/strong>

Humans have used drugs for various reasons throughout history, including medicine, social interaction<\/strong>, and relaxation<\/strong>.

Our brains have specific areas that respond to natural rewards like food, social connections, and sex – these form the brain’s reward system<\/strong>. Interestingly, drugs activate these same regions, triggering intense feelings of pleasure, such as euphoria and improved focus<\/strong>.

Over time, the brain learns to associate<\/strong> drugs with pleasure, reinforcing repeated use.

For people with schizophrenia or stimulant addiction, the craving for these substances can persist even when they no longer bring pleasure<\/strong>, leading to compulsive drug-seeking behavior despite negative consequences.<\/p>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

What happens to the brain on amphetamines?<\/strong><\/p>\n\n\n\n

Amphetamines interfere with<\/strong> the brain\u2019s normal chemical balance by blocking the reuptake<\/strong> of dopamine and norepinephrine, which causes their levels to rise in the brain<\/strong>. Amphetamines also affect the release of these chemicals within brain cells<\/strong>, further increasing their concentration. This buildup creates a spike of pleasure and euphoria<\/strong>, which can lead to a cycle of reward and addiction<\/strong>.<\/p>\n\n\n\n

However, prolonged use can alter brain structures involved in decision-making and impulse control, particularly the prefrontal cortex<\/strong>.

Research suggests that overstimulation of dopamine pathways may increase glutamate levels<\/strong>, disrupting brain function and contributing to psychotic symptoms, similar to those seen in schizophrenia.<\/p>\n\n\n\n

\u2018\u2019In essence, amphetamines not only trigger pleasurable sensations but can also disrupt important brain functions, potentially leading to serious mental health issues over time.\u2019\u2019<\/strong><\/p>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

The hidden dangers of amphetamines<\/strong><\/p>\n\n\n\n

Amphetamines<\/strong>, including drugs like ecstasy <\/strong>(3,4-Methylenedioxymethamphetamine (MDMA)) and methamphetamine<\/strong>, are known to boost energy, focus, and alertness<\/strong> while reducing the feeling of fatigue.

However, they come with side effects<\/strong> such as hyperactivity, anxiety, aggression, and sleep problems.

These drugs can also cause rapid heartbeats, high blood pressure, and other heart-related issues<\/strong>.

One of the most severe<\/strong> risks of amphetamine use is the potential for psychotic disorders<\/strong>.

The consequences of addiction affect not just the individual, but also their family, community, and the healthcare system<\/strong>.<\/p>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

How widespread is the global use of psychostimulants?<\/strong><\/p>\n\n\n\n

Psychostimulants like cocaine, amphetamines, and newer substances are widely used around the world.

Psychostimulants like cocaine, amphetamines, and newer stimulants<\/strong> are among the most widely used drugs worldwide. In 2019, the United Nations<\/strong> estimated 18 million people used cocaine globally. In the Americas alone, authorities seized over 1,200 tons of cocaine, methamphetamines<\/strong>, and amphetamines, reflecting the scale of the issue.<\/p>\n\n\n\n

While usage varies across regions, stimulant abuse remains a persistent global challenge<\/strong>.<\/p>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

Who is most affected by stimulant use disorder?<\/strong><\/p>\n\n\n\n

Stimulant use disorder (StUD), involving drugs like cocaine and amphetamines<\/strong>, affects a significant portion of the population.

Data from the U.S. show that approximately 0.2% of individuals aged 12 and older struggle with stimulant addiction<\/strong>, with slightly higher rates among teenage girls aged 12- 17<\/strong>. Among adults, young people aged 18-29<\/strong> are the most affected.

Intravenous <\/strong>stimulant use is more common among men<\/strong> than women.<\/p>\n\n\n\n

Non-prescribed stimulant use is widespread among high school and college students, with 5-35% reporting use in the past year.<\/strong><\/p>\n\n\n<\/div><\/div><\/div><\/div>

\n\n\n\n

Risk factors for developing stimulant use disorder<\/strong><\/p>\n\n\n\n

Risk factors for developing stimulant use disorder include both personal and environmental<\/strong> influences. <\/p>\n\n\n\n

People with mental health conditions (i.e. bipolar disorder, schizophrenia), or other substance use disorders are at higher risk<\/strong> of developing stimulant addiction or relapsing.<\/p>\n\n\n\n

Environmental factors<\/strong> play a big role, especially for teens. Those exposed to cocaine before birth or growing up in households where parents use drugs are more likely to develop issues with stimulants. <\/p>\n\n\n\n

Exposure to community violence<\/strong>, living in unstable homes<\/strong>, having mental health challenges<\/strong>, or spending time with drug users and dealers also<\/strong> increases the risk.<\/p>\n\n\n\n


<\/p>\n\n\n\n

How do stimulants lead to addiction?<\/strong>

Substance use disorders affect people of all age groups and social classes but are most common among those between the ages of 12 and 25<\/strong>.

Many individuals start using stimulant<\/strong>s, like methamphetamine or prescription medications, in their early twenties<\/strong>, often to manage weight<\/strong> or boost performance in school, work<\/strong>, or sports<\/strong>.

Regular use can quickly lead to addiction<\/strong>, especially with smoking or injecting stimulants, which can result in severe addiction within weeks or months<\/strong>.

Patterns of use can range from occasional bingeing to daily use<\/strong>, with tolerance often reducing the pleasurable effects over time.<\/p>\n\n\n\n
