Myth Busters
Some of the most common beliefs about teens and substances are outdated, incomplete, or simply wrong. Here's what the research actually shows.
General Myths
Before we get into specific substances, it helps to start with the bigger picture. Many of the most common beliefs about parenting and prevention are more complicated than they seem. Here are a few worth a second look.
"The kids don't even notice when we're drinking."
Tap to bust itKids notice far more than we think. Research shows children as young as 3 to 5 can recognize the smell of alcohol and begin associating it with adult behavior. They pick up on mood shifts and routines, and what we model early sticks with them.
Tap to flip back"It's good for them to see how to drink responsibly."
Tap to bust itEarly exposure to adult drinking, especially at social events, tends to normalize alcohol rather than teach moderation. Children ages 4 to 6 internalize what they see, and the more they watch parents drink, the more they associate alcohol with fun and social life, shaping their beliefs before they ever take a sip.
Tap to flip back"They're too young to understand what's happening."
Tap to bust itKids start forming ideas about alcohol far earlier than expected, sometimes as young as preschool. Even if they don't fully understand it, they're watching and learning from what we do. What we model matters, and our kids are paying attention.
Tap to flip back"So many other parents drink at events, it's normal."
Tap to bust itWhat's typical isn't always what's best. Many parents quietly wish for more alcohol-free options. Nearly half of adults say they're trying to drink less, and about 1 in 4 aren't drinking at all. When one parent makes the first move, it gives others permission to do the same.
Tap to flip back"There's not much a parent can really do."
Tap to bust itParents have real influence. Teens are less likely to develop substance problems when parents provide strong support, set clear rules, and communicate consistent attitudes. Consistent, positive family involvement is one of the strongest protective factors there is.
Tap to flip back"Everyone's kid is doing it anyway."
Tap to bust itTeens consistently overestimate how many of their peers use substances. Social media, older peers, and cultural messaging exaggerate how common and low-risk it really is, and that perceived norm itself increases risk. Most teens are using less than their peers assume.
Tap to flip backAlcohol
Alcohol is often treated as the most familiar and least worrying substance, which is exactly why the myths around it are so persistent. Here's what the research actually tells us about teens and drinking.
"A little supervised drinking at home teaches responsibility."
Tap to bust itResearch shows the opposite. Teens allowed to drink under adult supervision at home are more likely to drink outside the home and binge drink, which increases their risk of harm. Early permission normalizes alcohol and raises the likelihood of problems later.
Tap to flip back"Teen drinking is a normal rite of passage."
Tap to bust itUnderage drinking is neither inevitable nor harmless. During adolescence, the brain is still developing the areas responsible for judgment, impulse control, and decision-making, and alcohol can interfere with that process.
Tap to flip back"Alcohol affects teens the same way it affects adults."
Tap to bust itAlcohol hits adolescents harder and faster. Even at low levels it slows reaction time, impairs judgment, and reduces coordination. Because teens are still building foundational brain and body systems, these effects can last longer and carry more immediate consequences.
Tap to flip back"Starting a little earlier doesn't really make a difference."
Tap to bust itThe earlier a teen begins drinking, the greater the risk of developing alcohol use disorder later in life. Starting before age 14 significantly increases that risk. Delaying first use is one of the strongest protective factors parents have.
Tap to flip back"Drinking is just a social thing, it won't affect their mental health."
Tap to bust itA history of adolescent alcohol use is associated with mental health disorders such as anxiety and depression, both during the teen years and later in life. Alcohol disrupts the developing brain systems that regulate emotion, making it harder for teens to manage stress and mood.
Tap to flip back"Most teen drinking deaths happen because they decided to drive drunk."
Tap to bust itDrunk driving is extremely dangerous, but it accounts for only about a third of underage deaths linked to alcohol. The other two-thirds come from alcohol-related causes such as homicide, suicide, poisoning, and other accidents. The risks of teen drinking go far beyond getting behind the wheel.
Tap to flip backCannabis
Today's cannabis is far more potent than it was a generation ago, and a lot of the old assumptions no longer hold up. Let's take a look at what has changed.
"It's natural, so it's basically harmless."
Tap to bust itNatural doesn't mean safe. Today's cannabis is a highly processed product, and regular adolescent use is linked to lasting disruption of brain development and higher rates of depression, suicidality, and psychosis.
Tap to flip back"Cannabis isn't addictive."
Tap to bust itResearch clearly shows cannabis can be addictive, especially for adolescents whose brains are more vulnerable to reward-based learning. Higher-THC products raise the likelihood of dependence and withdrawal symptoms like irritability, sleep disruption, and cravings.
Tap to flip back"It's the same weed I grew up with."
Tap to bust itIt isn't. Today's vapes, edibles, and concentrates carry THC levels many times higher than anything from a generation ago. This is a fundamentally different and more potent drug.
Tap to flip back"A little cannabis helps my teen relax."
Tap to bust itIf a teen is using cannabis to manage anxiety, stress, or pain, that signals an underlying need worth understanding. Teen cannabis use is linked to higher rates of depression and anxiety and a greater risk of psychosis and bipolar disorder later in life.
Tap to flip back"Cannabis doesn't really affect the teenage brain."
Tap to bust itDuring adolescence the brain is actively building the systems for learning, memory, and emotional regulation. Higher-potency cannabis can interfere with that process and potentially alter the trajectory of normal brain development.
Tap to flip back"The cannabis industry isn't targeting kids."
Tap to bust itLike tobacco before it, cannabis marketing often uses flavors, packaging, and social-media-friendly branding that appeal to younger audiences. Products are designed to feel familiar, accessible, and low-risk to teens.
Tap to flip backNicotine
Vaping and Zyn reshaped what nicotine use looks like, and many of the beliefs parents carry haven't caught up. Here are the ones worth reconsidering.
"Vaping is basically harmless, it's just water vapor."
Tap to bust itIt isn't water vapor. Vape aerosol carries nicotine and other chemicals, and nicotine disrupts the developing teen brain, affecting focus, memory, and mood well into the mid-20s.
Tap to flip back"Tobacco-free pouches like Zyn are safe."
Tap to bust it"Tobacco-free" isn't risk-free. Pouches still deliver high doses of nicotine, with the same addictive power and health risks, just in a more discreet form.
Tap to flip back"If they only vape socially, they won't get hooked."
Tap to bust itThe teenage brain is especially sensitive to nicotine's grip on the reward system. Dependence can develop fast, often faster than parents expect, even from occasional use.
Tap to flip back"Vaping is a safer swap than cigarettes."
Tap to bust itFor a teen who never smoked, vaping isn't a safer swap, it's a new addiction. And early nicotine use makes future cigarette smoking more likely, not less.
Tap to flip back"They'll grow out of it, it's just a phase."
Tap to bust itNicotine dependence formed in adolescence often carries into adulthood. The earlier nicotine use begins, the harder it is to quit and the more likely it becomes a long-term habit.
Tap to flip back"The flavors are just for taste, they don't matter."
Tap to bust itFlavors are a key reason young people start and keep vaping. The industry uses sweet and fruity flavors specifically because they make nicotine more appealing and easier to tolerate for new users.
Tap to flip backPsychedelics
As psychedelics get more attention in the news and popular culture, it's easy for teens and parents alike to lose sight of the risks. Here's what to keep in mind.
"Psychedelics are natural, so they're safe."
Tap to bust itMany psychedelics come from plants or fungi, but that doesn't make them risk-free. They can produce intense changes in perception, judgment, mood, and behavior that are difficult for teens to navigate safely.
Tap to flip back"If they're being studied as medicine, they must be fine for teens."
Tap to bust itResearch on psychedelic-assisted therapy involves carefully controlled settings with adults. That's very different from unsupervised use by adolescents, and the two should not be confused.
Tap to flip back"Mushrooms are harmless, it's not like other drugs."
Tap to bust itThe altered consciousness psychedelics bring on can lead to a higher probability of accidents, and in some cases, accidental deaths. Impaired judgment during a psychedelic experience raises the risk of injury and unsafe decisions.
Tap to flip back"You always know what you're getting with mushrooms."
Tap to bust itPotency is unpredictable. Products sold online, through social media, or in informal markets may contain highly concentrated psilocybin, other psychoactive substances, or undisclosed ingredients.
Tap to flip back"Psychedelics are good for mental health."
Tap to bust itFor teens, psychedelics can trigger anxiety, panic, paranoia, or frightening experiences, especially in unfamiliar settings or for those vulnerable to mental health challenges. Adolescent use has been linked to early-onset psychosis and depressive episodes.
Tap to flip back"It's just a one-time experience, no lasting harm."
Tap to bust itA single experience can lead to lasting effects. Research links adolescent hallucinogen use to adverse outcomes including early-onset psychosis, and effects on a developing brain can be unpredictable and enduring.
Tap to flip backOpioids (like Fentanyl)
Opioids can feel like a distant concern until they aren't. Understanding the realities now, before they ever come up, is one of the most protective things you can do.
"My kid would never use hard drugs, so fentanyl isn't a risk."
Tap to bust itToday's fentanyl crisis isn't about seeking out hard drugs. It's often hidden in counterfeit pills or mixed into other substances without the user knowing. A teen who'd never consider themselves at risk can still encounter it through a single decision.
Tap to flip back"It's just one pill, how dangerous can it be?"
Tap to bust itA single exposure can be life-threatening. Fentanyl is a powerful synthetic opioid, and because it's so potent, one counterfeit pill can contain a lethal dose.
Tap to flip back"Pills from friends are safer than street drugs."
Tap to bust itCounterfeit pills are designed to look exactly like real prescription medication, but may contain fentanyl. There's no way to know by looking, and pills shared by friends can be just as dangerous.
Tap to flip back"You can tell if a pill is fake or laced."
Tap to bust itYou can't tell by sight, smell, or taste. Counterfeit pills are pressed to mimic real medications, and fentanyl is odorless and colorless. The only way to reduce risk is to avoid pills not prescribed directly by a doctor.
Tap to flip back"Naloxone is only for people with addiction."
Tap to bust itNaloxone (Narcan) can reverse an opioid overdose in anyone, and it's a simple, safe tool any parent can carry. Having it on hand can save a life in the minutes that matter most.
Tap to flip back"This is a big-city problem, not something in our community."
Tap to bust itFentanyl has reached communities everywhere, including Marin. Because it can appear in any counterfeit pill, no community is exempt, which is why awareness matters no matter where you live.
