Stay Curious, Stay Educated.
The more we know about drugs and alcohol — what they are, what they look like, and how they affect people — the easier it is to look out for ourselves and each other. Being informed can help us avoid serious risks like addiction, overdose, and other dangerous situations, including death. Knowledge about drugs and alcohol helps us recognize signs that may mean someone is in trouble, and talking about it helps break the stigma that keeps so many people from getting help when they need it.
Substance use is not uncommon. Unfortunately, neither is using without knowing exactly what you’re taking or what is going on in your mind and body when you use. That’s why asking questions and getting information from trusted sources matters. We all know that you can’t believe everything you read or hear – it’s way too easy for people to post whatever they want, true or false. Take some time to read through the info below and note our legit sources. You can also check out (link to AI info) to learn more about how to search wisely.

What are stimulants or uppers?
“Uppers” is a slang term for stimulants. Stimulants/Uppers are a group of drugs that increase energy, attention, and alertness, and can boost mood. Stimulants can come in a pill, powder, or crystal form.
- Common prescription stimulants: amphetamine (Adderall®), methylphenidate (Ritalin®)
- Common illegal stimulants: cocaine, methamphetamines/meth, MDMA, crack, bath salts
- Legal stimulants: caffeine, nicotine (21+), pre-workout supplements, energy drinks
What do stimulants and uppers do?
Stimulants and uppers increase your heart rate and can increase energy and alertness, and can boost mood by speeding up messages that are being sent between your brain and central nervous system. This is why coffee can make you feel more energized. While coffee is a legal stimulant and generally considered safe in a controlled amount, some stimulants can be very dangerous because of how strong they are. Each stimulant also works differently in the brain and some stimulants, like meth, can cause major changes in the brain.
Stimulants can cause high blood pressure, anxiety, insomnia (can’t sleep at night), little or no hunger, and can be very addictive. Taking larger doses or using it for a long time can cause more side effects like dizziness, tremors, chest pain, excessive sweating, vomiting, abdominal cramps, and death.
When stimulants start to wear off, withdrawal symptoms can be experienced and feel like a “crash.” Withdrawal symptoms include feeling shaky, weak, dizzy, and overall exhaustion and depression.

- Methamphetamines is one of the most common drugs involved in overdose deaths in Pima County.
- Summer time is especially dangerous for people who use stimulants. Since stimulants can increase heart rate and raise body temperature, it can cause someone to overheat more easily. In Arizona, we know how hot and deadly it can get in the summer time. Click here to learn more about how to stay safe in the heat!
What are depressants or downers?
“Downers” is a slang term for depressants. Depressants/Downers are a group of drugs that produces a “sedative” effect which could look like drowsiness, relaxation, and slowed reaction time. Opposite to stimulants, it decreases alertness and focus. Depressants can come in a pill, powder or crystal form.
- Common prescription depressants: benzodiazepines (Xanax®, Klonopin®, Librium®), barbiturates, prescription opioids
- Common illegal depressants: Tranq/xylazine, illegally made benzodiazepines, illegal opioids (heroin, fentanyl)
- Legal depressants: Alcohol (21+)
What do depressants and downers do?
Depressants or downers slow down the messages between your brain and the central nervous system, causing someone to feel more relaxed or tired and can reduce feelings of pain. Typically, many prescription depressants are used to treat anxiety or pain.
Depressant use can cause extreme drowsiness, vomiting, unconsciousness, shallow breathing, black outs/memory loss, and even death. Since depressants can slow the central nervous system, it also slows breathing and heart rate. If too much is taken, it can cause very low oxygen levels in the body and result in a coma or death.
Withdrawal symptoms from depressants can be severe and potentially life threatening. Withdrawal symptoms could include severe anxiety, panic attacks, delirium, rapid heart rate, sweating, and in more severe cases, seizures.
What are things to know about depressant use?
- Xylazine is a new drug present in Pima County, also known as “Tranq” because it is an animal tranquilizer. Xylazine can cause wounds in the skin. Click here to learn more about xylazine!
What are opioids?
Opioids can be natural or synthetic (made in a lab). Doctors can prescribe opioids to reduce or treat pain. Both illegal and prescription opioids can lead to an addiction, overdose, and even death.
Opioids are also considered depressants/downers and can come in pill, powder, or crystal form.
- Common prescription opioids: oxycodone (OxyContin®, Percocet®), hydrocodone (Vicodin®), prescription fentanyl, codeine, tramadol, hydromorphone
- Common illegal opioids: heroin, fentanyl, counterfeit pills (M-30’s, percs)
What do opioids do?
Opioids block pain receptors (meaning you feel less pain) and can cause changes in mood and thinking abilities, including feelings of relaxation and happiness. It can also slow your respiratory system (your breathing).
Opioids are highly addictive and your body can develop a dependence on them fairly quickly, in a matter of a few days. Once you develop a dependence, your brain and body feel like they can no longer function normally without them. Dependence can bring withdrawal symptoms such as higher sensibility to pain, cramps, nausea, vomiting, chills, diarrhea, and more.
- Often times, people continue to use to avoid withdrawal symptoms. As people use more often, they may develop a tolerance, which means they may need to take larger doses and/or take it more often since their body is used to the substance. This puts them at higher risk of health problems, overdoses, and deaths.
What are things to know about opioid use?
- Fentanyl is found in many illicit drugs and is highly addictive and dangerous. In Pima County, fentanyl is one of the most common drugs involved in overdose deaths.
- Narcan (naloxone) can reverse an opioid overdose. Click here to learn more about Narcan!
- There are medications that can treat opioid use disorder, if you have difficulties stopping or managing opioid use.
What is alcohol?
Alcohol is also considered a depressant or downer and is usually referred to as “alcohol” or “booze,” can be distinguished by type (vodka, whiskey, tequila, beer, wine, seltzer, etc.), or drink category (cocktail, brew, etc). They typically only come in liquid form as a drink.
What does alcohol do?
At first, alcohol can give feelings of increased energy, euphoria, relaxation, and decreased anxiety, but also impacts your thinking, judgement, and vision negatively. Over time, it can also increases anxiety and makes your quality of sleep worse (FYI –“passing out” is not the same as getting good sleep).
When you quit or stop alcohol use, it can cause withdrawal symptoms. Withdrawal symptoms can range from mild symptoms like headaches, anxiety, sweating, upset stomach, and fatigue, to severe forms like delirium tremens which can cause tremors, confusion, hallucinations, seizures, organ damage, and death.
What are things to know about alcohol use?
- Drinking alcohol with any other substance, even legal or prescription drugs, increases chance of addiction, injury, and death.
- There are medications available to treat alcohol use disorder, if you have difficulties stopping or managing alcohol use.
- Alcohol is the most common substance used by people under 21 in the United States. Underage alcohol use can lead to physical and mental health issues. This can include an increased risk of physical harm, slower brain development, and increased risk of addiction to alcohol. There are also legal consequences from underage drinking like being arrested, serving time in jail, losing your driver’s license, and thousands of dollars in fines.
- Alcohol is legal for adults ages 21 years and older in the United States, but there are still potential health consequences with drinking.
- If you are drinking, it is illegal to drive a vehicle of any kind (cars, bikes, scooters). When drinking alcohol, people’s thinking and reaction time is slower and your vision can be impaired. People have lost their lives due to car crashes caused by alcohol use. If you are drinking, do not drive. Call a friend, trusted adult, or an Uber to get home safely.
What is marijuana?
Marijuana is often called by other names including weed, pot, and cannabis. Typically it refers to dried leaves, flowers, stems, and seeds of the Cannabis plant, but it can also be extracted into different and stronger forms, such as oil, wax, shatter, and extracts. It contains a chemical called tetrahydrocannabinol (THC) which is what causes the “high.” In addition to THC, cannabidiol (CBD) is a compound that is found in marijuana and does not cause the “high.” You may see CBD products sold with or without THC.
Marijuana can cause changes in mood, thoughts, and perceptions of reality.
What does marijuana do?
People respond differently to marijuana depending on their biology, type of marijuana (strain), and what other substances are in their system. In general, people use marijuana for the feeling of being “high”, including feeling relaxed, heightened senses, and time moving differently. Commonly, people experience increased heart rate, dry mouth, red eyes, and increased appetite. It can also cause paranoia, panic, and in extreme cases psychosis (not knowing what is real and/or hallucinations).
Using marijuana for a long time does have some long-term health risks and people can get addicted to marijuana. If someone uses frequently and for a long time, it can impact decision-making skills, memory, and is even linked to higher rates of mental health conditions (like anxiety and depression). If someone is using marijuana through smoking, it is still harmful to the lungs, much like smoking cigarettes.
What are things to know about marijuana?
- Compounds of marijuana have been approved for medical purposes like treating seizures (CBD), nausea in patients with cancer (THC-like chemical), and to help increase appetite in individuals who don’t feel like eating (THC-like chemical). But, like other medications, make sure you talk to your doctor about it first.
- While marijuana is legal in Arizona for reactional and medicinal use for adults 21 years and older, it is still illegal on a federal level (nationwide).
- 1 in 6 people who start using marijuana before the age of 18 can become addicted to marijuana.
- The association between marijuana and schizophrenia is stronger in people who start using marijuana at an earlier age and use marijuana more frequently. If you have a family history of mental illness conditions, like schizophrenia or psychosis, marijuana use may trigger similar symptoms.
- Marijuana can have impacts on your ability to drive safely. It can impact your reaction time, coordination, and concentration. It is dangerous and illegal to drive while under the influence.
What is nicotine?
Nicotine is a highly addictive chemical compound present in a tobacco plant. All tobacco products contain nicotine, including cigarettes, non-combusted cigarettes (commonly referred to as “heat-not-burn tobacco products” or “heated tobacco products”), cigars, smokeless tobacco (such as dip, snuff, snus, and chewing tobacco), hookah tobacco, and most e-cigarettes or vapes.
Using any tobacco product can lead to nicotine addiction. This is because nicotine can change the way the brain works, causing cravings for more of it.
Why is it difficult to quit smoking or vaping?
Because the brain is still developing, young people have a higher risk of becoming addicted to the nicotine in tobacco products than adults.
Many people don’t understand how easy it is to become addicted to tobacco products. The younger a person is when they start using tobacco, the more likely they are to become addicted. (Source)
Nicotine exposure during adolescence can disrupt normal brain development. (Source)
Because of nicotine’s powerfully addictive nature and major effects on the developing brain, no tobacco products are safe for youth to use.

PolySubstance Use
The use of more than one drug or drug type at the same time is called polysubstance use. There is no safe way to mix drugs, and mixing drug types (like taking an upper with a downer) does not cancel out the risks. For example, some people will take a downer after using an upper thinking it will calm down the effects of the stimulant. But it doesn’t exactly work like that, it just makes it more unpredictable and can greatly increase the risk of heart attack and overdose. There is no way of knowing how the body will react to different combinations, so your experience may vary. (Source)
- Mixing Uppers & Uppers
- Combining multiple uppers (stimulants) like meth and cocaine can increase your risk of a heart attack, brain injury, liver damage, & stroke. Stimulants can increase your heart rate and blood pressure to dangerous levels and increase your risk of several serious health problems.
- Mixing Downers & Downers
- Combining multiple downers (depressants) like opioids and benzos can increase your risk of damage to the brain and other organs, overdose, and death. Downers can slow down your breathing, so combining the multiple downers can lead to an overdose more easily.
- Mixing Uppers & Downers
- Combining uppers (stimulant) and downers (depressant) can modify or even hide the effects of the other drug, making it easier to overdose.
- Mixing Alcohol & Uppers/Downers
- Alcohol is a depressant with similar effects to other downers. Mixing alcohol with other drugs can increase your risk of an overdose and can cause serious damage to the brain, heart, and other organs.
Counterfeit pills
Fake pills (also known as counterfeit pills) can look like real medications. Every year, millions of counterfeit pills are made to look like real prescription medications you can get from a doctor. As of January 2026, 29% of counterfeit pills tested at DEA laboratories contain a deadly dose of fentanyl. (Source)
Counterfeit pills:
- can have incorrect dosages (too much, too little, or inconsistent)
- can have illegal substances in the pills (i.e. fentanyl or meth)
- are not tested or regulated, making them even more dangerous
The most common examples include:
- Oxycodone (OxyContin®, Percocet®)
- Hydrocodone (Vicodin®)
- Benzodiazepines (Xanax®, Valium®)
- Amphetamines (Adderall®)
If someone offers you a pill, there’s no way to know what’s inside or if it really is that medications. It is not worth the risk!
Do you think you can spot the fake pills?








why does it matter?
Counterfeit pills that contain fentanyl can be deadly. You can’t see, smell, or taste it. Taking a small amount, can cause an opioid overdose. A lethal dose (which is the the amount that is too much for the body to handle) of fentanyl is about two milligrams, equivalent in size to a few grains of salt, which is the amount that would fit on the tip of a pencil!
To reduce the risk of a deadly overdose, naloxone should be readily available and counterfeit pills can be tested to see if fentanyl is in the pills. Being prepared to respond to an overdose can help you save a life!
