In recent years, methamphetamine meth use has become increasingly widespread. Methamphetamine is a type of amphetamine that can be made from ingredients that are readily available e.
Stimulant users seek a euphoric high , feelings of intense elation and pleasure, especially in those users who take the drug via intravenous injection or smoking.
MDMA 3. It is typically consumed in pill form. Users experience increased energy, feelings of pleasure, and emotional warmth. Repeated use of these stimulants can have significant adverse consequences. Users can experience physical symptoms that include nausea, elevated blood pressure, and increased heart rate.
In addition, these drugs can cause feelings of anxiety, hallucinations, and paranoia Fiorentini et al. Normal brain functioning is altered after repeated use of these drugs. For example, repeated use can lead to overall depletion among the monoamine neurotransmitters dopamine, norepinephrine, and serotonin. Depletion of certain neurotransmitters can lead to mood dysphoria, cognitive problems, and other factors.
Caffeine is another stimulant drug. While it is probably the most commonly used drug in the world, the potency of this particular drug pales in comparison to the other stimulant drugs described in this section.
Generally, people use caffeine to maintain increased levels of alertness and arousal. While caffeine may have some indirect effects on dopamine neurotransmission, its primary mechanism of action involves antagonizing adenosine activity Porkka-Heiskanen, Adenosine is a neurotransmitter that promotes sleep. Caffeine is an adenosine antagonist, so caffeine inhibits the adenosine receptors, thus decreasing sleepiness and promoting wakefulness. In , Kromann and Nielson reported on a case study of a year-old woman who suffered significant ill effects from her use of caffeine.
The woman used caffeine in the past to boost her mood and to provide energy, but over the course of several years, she increased her caffeine consumption to the point that she was consuming three litres of soda each day. Although she had been taking a prescription antidepressant, her symptoms of depression continued to worsen and she began to suffer physically, displaying significant warning signs of cardiovascular disease and diabetes.
Upon admission to an outpatient clinic for treatment of mood disorders, she met all of the diagnostic criteria for substance dependence and was advised to dramatically limit her caffeine intake.
Once she was able to limit her use to less than 12 ounces of soda a day, both her mental and physical health gradually improved. Despite the prevalence of caffeine use and the large number of people who confess to suffering from caffeine addiction, this was the first published description of soda dependence appearing in scientific literature.
Nicotine is highly addictive, and the use of tobacco products is associated with increased risks of heart disease, stroke, and a variety of cancers. Nicotine exerts its effects through its interaction with acetylcholine receptors. Acetylcholine functions as a neurotransmitter in motor neurones. In the central nervous system, it plays a role in arousal and reward mechanisms. Nicotine is most commonly used in the form of tobacco products like cigarettes or chewing tobacco; therefore, there is a tremendous interest in developing effective smoking cessation techniques.
To date, people have used a variety of nicotine replacement therapies in addition to various psychotherapeutic options in an attempt to discontinue their use of tobacco products. Vaping as a means to deliver nicotine is becoming increasingly popular, especially among teens and young adults.
Vaping uses battery-powered devices, sometimes called e-cigarettes, that deliver liquid nicotine and flavourings as a vapour. Originally reported as a safe alternative to the known cancer-causing agents found in cigarettes, vaping is now known to be very dangerous and has led to serious lung disease and death in users.
An opioid is a category of drugs that includes heroin, morphine, methadone, and codeine. Opioids have analgesic properties; that is, they decrease pain. Humans have an endogenous opioid neurotransmitter system—the body makes small quantities of opioid compounds that bind to opioid receptors reducing pain and producing euphoria.

There is no doubt that some types of psychoactive drugs are ubiquitous, such as sedatives, opiods, cannabis, hallucinogens and tobacco.
The list includes both; ones that come with psychoactive effects naturally and once that are synthesized in the laboratory. Regardless of how they are manufactured or grown, these psychoactive drugs have a strong impact on your brain receptors. That is what makes considering different aspects, such as age, method of administration, setting and purity, highly important before taking them. This might sound surprising for some people, but most patients who come to 1 st Step Behavioral Health Center for treatment are young teenagers.
People who reduce their caffeine intake often report being irritable, restless, and drowsy, as well as experiencing strong headaches, and these withdrawal symptoms may last up to a week. Most experts feel that using small amounts of caffeine during pregnancy is safe, but larger amounts of caffeine can be harmful to the fetus Health Canada, Nicotine is a psychoactive drug found in tobacco and other members of the nightshade family of plants, where it acts as a natural pesticide.
Nicotine is the main cause for the dependence-forming properties of tobacco use, and tobacco use is a major health threat. Nicotine creates both psychological and physical addiction, and it is one of the hardest addictions to break.
Nicotine content in cigarettes has slowly increased over the years, making quitting smoking more and more difficult. Nicotine is also found in smokeless chewing tobacco. People who want to quit smoking sometimes use other drugs to help them. For instance, the prescription drug Chantix acts as an antagonist, binding to nicotine receptors in the synapse, which prevents users from receiving the normal stimulant effect when they smoke.
At the same time, the drug also releases dopamine, the reward neurotransmitter. In this way Chantix dampens nicotine withdrawal symptoms and cravings. In many cases, people are able to get past the physical dependence, allowing them to quit smoking at least temporarily. In the long run, however, the psychological enjoyment of smoking may lead to relapse.
Cocaine is an addictive drug obtained from the leaves of the coca plant Figure 6. In the late 19th and early 20th centuries, it was a primary constituent in many popular tonics and elixirs and, although it was removed in , was one of the original ingredients in Coca-Cola.
Today cocaine is taken illegally as a recreational drug. Cocaine has a variety of adverse effects on the body. It constricts blood vessels, dilates pupils, and increases body temperature, heart rate, and blood pressure. It can cause headaches, abdominal pain, and nausea. Since cocaine also tends to decrease appetite, chronic users may become malnourished. The faster the drug is absorbed into the bloodstream and delivered to the brain, the more intense the high.
Injecting or smoking cocaine produces a faster, stronger high than snorting it. However, the faster the drug is absorbed, the faster the effects subside. In order to sustain the high, the user must administer the drug again, which may lead to frequent use, often in higher doses, over a short period of time National Institute on Drug Abuse, a.
Cocaine has a safety ratio of 15, making it a very dangerous recreational drug. An amphetamine is a stimulant that produces increased wakefulness and focus, along with decreased fatigue and appetite.
Amphetamines are used in prescription medications to treat attention deficit disorder ADD and narcolepsy, and to control appetite. Some brand names of amphetamines are Adderall, Benzedrine, Dexedrine, and Vyvanse. Meth is a highly dangerous drug with a safety ratio of only Although the level of physical dependency is small, amphetamines may produce very strong psychological dependence, effectively amounting to addiction. Continued use of stimulants may result in severe psychological depression.
MDMA is a very strong stimulant that very successfully prevents the reuptake of serotonin, dopamine, and norepinephrine.
In contrast to stimulants, which work to increase neural activity, a depressant acts to slow down consciousness. A depressant is a psychoactive drug that reduces the activity of the CNS. Depressants are widely used as prescription medicines to relieve pain, to lower heart rate and respiration, and as anticonvulsants. Depressants change consciousness by increasing the production of the neurotransmitter GABA and decreasing the production of the neurotransmitter acetylcholine, usually at the level of the thalamus and the reticular formation.
The most commonly used of the depressants is alcohol , a colorless liquid, produced by the fermentation of sugar or starch, that is the intoxicating agent in fermented drinks Figure 6. Alcohol is the oldest and most widely used drug of abuse in the world. In low to moderate doses, alcohol first acts to remove social inhibitions by slowing activity in the sympathetic nervous system. In higher doses, alcohol acts on the cerebellum to interfere with coordination and balance, producing the staggering gait of drunkenness.
At high blood levels, further CNS depression leads to dizziness, nausea, and eventually a loss of consciousness. Alcohol use is highly costly to societies because so many people abuse alcohol and because judgment after drinking can be substantially impaired. Even people who are not normally aggressive may react with aggression when they are intoxicated.
Alcohol use also leads to rioting, unprotected sex, and other negative outcomes. When people are intoxicated, they become more self-focused and less aware of the social situation. As a result, they become less likely to notice the social constraints that normally prevent them from engaging aggressively, and are less likely to use those social constraints to guide them.
For instance, we might normally notice the presence of a police officer or other people around us, which would remind us that being aggressive is not appropriate.
But when we are drunk, we are less likely to be so aware. The narrowing of attention that occurs when we are intoxicated also prevents us from being cognizant of the negative outcomes of our aggression. Alcohol also influences aggression through expectations.
If we expect that alcohol will make us more aggressive, then we tend to become more aggressive when we drink. Barbiturates are depressants that are commonly prescribed as sleeping pills and painkillers. In small to moderate doses, barbiturates produce relaxation and sleepiness, but in higher doses symptoms may include sluggishness, difficulty in thinking, slowness of speech, drowsiness, faulty judgment, and eventually coma or even death Medline Plus, Related to barbiturates, benzodiazepines are a family of depressants used to treat anxiety, insomnia, seizures, and muscle spasms.
In low doses, they produce mild sedation and relieve anxiety; in high doses, they induce sleep. In the United States, benzodiazepines are among the most widely prescribed medications that affect the CNS. Toxic inhalants are also frequently abused as depressants. These drugs are easily accessible as the vapours of glue, gasoline, propane, hairspray, and spray paint, and are inhaled to create a change in consciousness.
Inhalants are some of the most dangerous recreational drugs, with a safety index below 10, and their continued use may lead to permanent brain damage. Opioids are chemicals that increase activity in opioid receptor neurons in the brain and in the digestive system, producing euphoria, analgesia, slower breathing, and constipation.
Opium is the dried juice of the unripe seed capsule of the opium poppy. Dopamine activity is often associated with reward and craving; therefore, drugs that affect dopamine neurotransmission often have abuse liability.
Drugs in this category include cocaine, amphetamines including methamphetamine , cathinones i. Crack Figure 3 is often considered to be more addictive than cocaine itself because it is smokable and reaches the brain very quickly. Crack is often less expensive than other forms of cocaine; therefore, it tends to be a more accessible drug for individuals from impoverished segments of society.
During the s, many drug laws were rewritten to punish crack users more severely than cocaine users. This led to discriminatory sentencing with low-income, inner-city minority populations receiving the harshest punishments.
Figure 3. Crack rocks like these are smoked to achieve a high. Department of Justice. Amphetamines have a mechanism of action quite similar to cocaine in that they block the reuptake of dopamine in addition to stimulating its release Figure 4.
While amphetamines are often abused, they are also commonly prescribed to children diagnosed with attention deficit hyperactivity disorder ADHD. It may seem counterintuitive that stimulant medications are prescribed to treat a disorder that involves hyperactivity, but the therapeutic effect comes from increases in neurotransmitter activity within certain areas of the brain associated with impulse control.
Figure 4. As one of their mechanisms of action, cocaine and amphetamines block the reuptake of dopamine from the synapse into the presynaptic cell.
In recent years, methamphetamine meth use has become increasingly widespread. Methamphetamine is a type of amphetamine that can be made from ingredients that are readily available e.
The cocaine, amphetamine, cathinones, and MDMA users seek a euphoric high , feelings of intense elation and pleasure, especially in those users who take the drug via intravenous injection or smoking.
