Good to Know

Cannabis. Marijuana. Weed. Mary Jane. Herb. Pot.

THC: the psychoactive chemical (active ingredient) that changes the brain and makes people feel physical effects.

CBD: the non-psychoactive chemical found in the cannabis plant.

Adults age 21 and over are free to possess marijuana and consume it in private.

Adults age 18 and over are allowed to use medical marijuana with a prescription.

Smoking: Cannabis (marijuana) is commonly smoked using pipes, water pipes called bongs, or hand-rolled cigarettes called joints.

Vaping: Vaporizers heat marijuana to release its active THC and the vapor is inhaled. Vaping often refers to nicotine use, but vape pens are also commonly used to inhale THC.

Dabbing: THC concentrates, like hash oil, wax, and shatter, can contain up to 60-80% THC and may take effect very quickly. High levels of THC can be dangerous.

Edibles: Candies, baked goods, teas, and sodas can contain more THC than a user is aware of. Edibles take longer to take effect, causing some users to consume too much.

Topical: Marijuana infused lotions, salves, and balms are sold for localized pain, inflammation, and skin
conditions. Some do not contain THC and do not make the user feel high. Most infused products contain THC and effects can be felt for hours

There are many reasons why people choose to use. For example:

  • To deal with stress, physical pain, or emotional suffering.
  • To relax or have fun, much like alcohol.
  • To address health issues as prescribed by a doctor.
  • Cannabis impairs decision making and driving skills.
  • Cannabis use by teens can impact brain development.
  • Research shows that using cannabis during pregnancy can cause health problems in newborns— including low birth weight (CDC).
  • Cannabis is harmful If ingested by young children or pets.
  • Like all substances, cannabis carries some risk of addiction.

Health Consequences for Youth

While we still have a lot to learn about the physical, emotional and mental consequences of underage non-medical marijuana use, we already know enough to know that it can be dangerous. It’s important for you to learn some of the negative health impacts so that you can help young people understand some of the risks they could be taking by using cannabis (marijuana).


Marijuana is addictive. It’s harder to stop using marijuana if you start at a young age. Youth who start using marijuana, alcohol or other drugs — even occasionally — may be more likely to continue using later in life.

Learning & Memory Loss

Youth who use marijuana regularly are more likely to have difficulty learning, memory issues, and lower math and reading scores. The more marijuana youth use, the harder it may be for them to learn. And the effects can last weeks after quitting.

Lower Athletic Performance

Marijuana smoke has many of the same chemicals as tobacco smoke, which are not healthy for lungs. Marijuana can impact a teen’s ability to learn new skills, even weeks after they last used. Marijuana can also affect athletic performance and coordination.

Harms Brain Development

Brain development is not complete until about age 25. For the best chance to reach their full potential, youth should not use cannabis.

Legal Consequences for Youth 

Getting caught with cannnabis (marijuana) can involve fines, public service hours, misdemeanor/felony charges and even possible loss of driver’s license. It can also cause a young adult to lose their parents’ trust, resulting in the loss of privileges. And if there’s one thing youth hate to hear, it’s “I’m not mad. I’m just disappointed.”

Loss of Financial Aid

Marijuana charges can result in the loss of federal financial aid for college, including: Perkins Loans, Pell Grants, Supplemental Educational Opportunity Grants, PLUS Loans, and Work-Study Programs.


Many employers still prohibit marijuana use by their employees, which could mean losing a job. Losing a job also means losing a job reference, which makes future employment even harder to get.

All minors under the age of 18 are prohibited from working in any occupation in a registered marijuana dispensary, any establishment that cultivates, produces, or sells marijuana or products that contain marijuana, and any non-medical marijuana social clubs.

Banned from Sports/Activities

If they’re caught using marijuana, they can be removed from sports teams and extracurricular activities, suspended, expelled or referred to drug counseling.

Pregnancy & Marijuana

How Marijuana Affects Pregnant & Breastfeeding Women

  • Marijuana During Pregnancy
    There is no known safe amount of marijuana to use while pregnant. That’s because no matter how it’s used (smoked, eaten, etc.), THC gets passed to your baby and may have a long-term impact on your child’s ability to learn. Talk to your doctor early in your pregnancy about marijuana use.
  • Marijuana While Breastfeeding
    If you use marijuana while breastfeeding, it gets passed to your baby. THC is stored in fat cells. That means THC stays in your breast milk, so “pumping and dumping” doesn’t work. THC gets into your breast milk and may affect your baby. Talk to your doctor if you have any questions.

    Medical Marijuana

    In general, it isn’t a good idea to use any medicines while pregnant or breastfeeding that aren’t recommended by a doctor. Talk to your doctor about a safer choice.

    Common Questions About Marijuana

    • Is marijuana safe to use while pregnant or breastfeeding?
      There is no known safe amount of marijuana use while pregnant or breastfeeding. There are some foods and medicines you can’t use while pregnant or breastfeeding because they might harm the baby. The same goes for marijuana. No matter how it’s used, if you use marijuana while pregnant or breastfeeding, THC gets passed to your baby.
    • It’s legal, so doesn’t that mean it’s safe?
      The fact that it’s legal does not make it safe. Using marijuana during pregnancy or while breastfeeding may harm your baby, just like alcohol or tobacco.
    • It’s natural, so doesn’t that mean it’s safe?
      Not all natural substances or plants are safe. Lead, tobacco and poisonous berries are great examples. Marijuana contains THC, which may harm a baby.
    • What about using it for medical reasons?
      A doctor can recommend marijuana in special cases, so a doctor can decide whether the benefits are greater than the risks. It is unsafe to use any medicines while pregnant or breastfeeding that are not recommended by a doctor. Talk to your doctor about safer choices that do not risk harming your baby.
    • Can I use it to treat my nausea?
      THC in marijuana may harm your baby. Talk to your health care provider about safer options that do not risk harming your baby.
    • Is it still harmful if I vape or eat it instead of smoke it?
      If you consume marijuana, you are consuming THC, which is passed to your baby and can cause harm.

      Secondhand Smoke

      Secondhand smoke from marijuana has many of the same cancer-causing chemicals as smoke from tobacco. A smoke-free environment is safest and healthiest. Don’t allow smoking in your home or around your baby

Legal Implications

Some hospitals test babies after birth for drugs. If your baby tests positive for THC at birth, Michigan law says the hospital must notify child protective services. Talk to your doctor early in your pregnancy to get the support you need to be healthy. Your doctor can help connect you with treatments that are confidential and nonjudgmental.

Talk to your doctor if you’re pregnant or breastfeeding and need help to stop using marijuana. Your treatment will be confidential.

You must be over 21

In order to possess or use cannabis (marijuana) you must either be a medical marijuana cardholder OR be 21 years of age or older. It’s that simple.

Don’t use in public

Using marijuana in any form (smoking, eating or vaping) isn’t allowed in public places, including amusement parks, ski resorts, sporting and music venues, state and national parks, campsites, playgrounds, sidewalks and roads, marijuana retail businesses, bars, restaurants and outdoor or rooftop cafes.

So where can you use it? Marijuana use is legal within the confines of private property. Just keep in mind that property owners, landlords, and rental companies can ban the use and possession of marijuana on their premises.

Federal land is under federal law

Cannabis (marijuana) is legal under State of Michigan law. Federally, it is not legal. If you’re on federal property, such as a national park or a border crossing, you can’t even have it in your possession.

Don’t cross state lines or international boundaries

It’s illegal to leave Michigan with any cannabis (marijuana) products – medical or non-medical. Mailing cannabis (marijuana) from Michigan is also illegal.

There’s a limit to how much you can grow

Michiganders can grow marijuana for personal use. As many as 12 plants per household.

The 12 plants should be indoors, or outside in a locked enclosure that is not easily visible from public areas. Growing on rental properties is subject to landlord approval.

Safety & Marijuana

Keep it out of sight

An adult who chooses to use should make sure the cannabis (marijuana) is not visible from the public eye.

Keep it locked up

An adult who chooses to use must take reasonable precautions to prevent unauthorized access by individuals under the age of 21. Ease of access is the #1 way youth and vulnerable populations obtain substances.

Store all marijuana products in a locked area, out of sight and out of reach of children. Keep cannabis (marijuana) in the child-resistant packaging from the retailer. Remember, how you store cannabis (marijuana) should change as your children get older. What works to protect a toddler from accidental ingestion may not work to protect a curious teenager who might actually be looking for it.

Accidental Ingestion

If your child eats or drinks marijuana, they may need immediate medical help. Some symptoms to look out for include: problems walking or sitting up, difficulty breathing, and becoming sleepy. If a child may have eaten marijuana, call the poison control hotline, 1-800-222-1222, or 911 if it’s an emergency.

If you’re a pet owner, you should also store your cannabis (marijuana) safely. Call a veterinarian if your pet is showing the following symptoms of ingesting cannabis (marijuana): depression and listlessness, loss of motor coordination, loss of balance, vomiting or low body temperature.
