Cannabis

Cannabis and Health

Cannabis, also called marijuana, pot, or weed, refers to all components of the cannabis sativa plant.

The cannabis plant contains over 100 compounds. This includes cannabidiol (CBD) which is not intoxicating, and delta-9 tetrahydrocannabinol (THC), which is the main intoxicating component in the plant.

Cannabis products can differ greatly. Dried cannabis has a higher average THC level now than it has before. Concentrates or edibles often have even higher amounts of THC. This can make it easy to accidentally use more than intended. If using cannabis, it's important to start with a low amount and go slowly so you don't take too much.

The way cannabis is used- by combustion (smoked or vaped), consumed through food or beverage, applied on the skin, or by heating concentrates to inhale (dabbing)- impact how fast the effects are felt, and how long they last. Inhaling cannabis typically results in feeling effects more quickly, while edibles take longer.

The human brain is developing through the mid-twenties. Research shows using cannabis before the brain is fully developed impacts the way the brain develops. This can create difficulties with memory/learning, processing, emotional regulation, REM sleep, and increase the likelihood of developing a cannabis use disorder (dependency). A growing body of research also indicates a higher risk of experiencing poor mental health outcomes.

Cannabis Smoke

Cannabis smoke has many of the same chemicals as tobacco smoke, which can harm lung health. More long-term research is needed to determine relationships between cannabis and cancer.

Secondhand cannabis smoke can be harmful to those exposed to it. Cannabis smoke contains chemicals and fine particles that are not healthy for the lungs. Secondhand cannabis smoke can contain solvents, pesticides, mold, and other chemicals used during the growing or manufacturing process. The risk is greater with untested products. Long-term exposure to secondhand cannabis smoke can damage arteries, increasing the risk of heart attack and stroke. There is also risk of feeling the effects of THC after being exposed to secondhand smoke which may impact ability to safely carry out tasks like driving.

Accidental Ingestions

Since 2017, Maine has seen a rise in cannabis use rates by youth and young adults. With the launch of legal adult use cannabis in Maine in 2020, it is more easily accessible. The rates of accidental ingestions by young children (ages 0-5) have increased since 2019. Effects of cannabis may be more severe in a young child who consumes cannabis.

Signs of accidental ingestion can include:

  • Sleepy/drowsy or unable to be woken up
  • Slurred speech
  • Fast heart rate
  • Difficulty breathing
  • Difficulty walking or sitting up

If you think a child has ingested cannabis, the Poison Control Hotline can help- call 1-800-222-1222. If the reaction is severe, call 911 or go to an emergency room.

Cannabis and Driving

Impaired driving laws also apply to driving under the influence of cannabis. Cannabis can impair coordination, slow reaction times, and slow decision making.

Some cannabis products, like edibles, are still impacting the brain several hours after use. It's important to make a safe plan to get where you need to go.
