Cannabis use does not come without risks or harms. It is your duty to understand cannabis and what effects it may have. Please act responsibly.

 

Chemical Compounds: THC & CBD

 

Cannabis plants produce chemical compounds known as cannabinoids. These compounds interact with our bodies via the endocannabinoid system. The two most well-known cannabinoids are THC (tetrahydrocannabinol) and CBD (cannabidiol).

 

THC

The most researched cannabinoid is delta-9-tetrahydrocannabinol (THC). THC is responsible for the way your brain and body respond to cannabis, including the high and intoxication. THC has some therapeutic effects but it also has harmful effects. Harmful effects may be greater when the strength of THC is higher.

 

The potency (concentration or strength) of THC in cannabis is often shown as a percentage of THC by weight (or by volume of an oil). THC potency in dried cannabis has increased from an average of 3% in the 1980s to around 15% today. Some strains can have an average as high as 30% THC.

 

CBD

Cannabidiol (CBD) is another cannabinoid. Unlike THC, CBD does not produce a high or intoxication. There is some evidence that CBD may block or lower some of the effects of THC on the mind. This may occur when the amount of CBD in the cannabis is the same or higher than the amount of THC. CBD is also being studied for its possible therapeutic uses.

HEMP

Cannabis that contains very low amounts of THC in its flowers and leaves (less than 0.3%) is classified as hemp.

Health Effects of Cannabis

 

Short-term health effects

The flowers and leaves of the cannabis plant are used for their ability to cause effects on the mind, including:

  • feeling high (euphoria)

  • a sense of well-being

  • relaxation

  • heightened sensory experiences:

  • sight

  • taste

  • smell

  • sound

 

While cannabis may make you feel relaxed and happy, your body and brain may also experience effects that are negative, unwanted and/or unpleasant.

 

Some of the short-term effects on your brain can include:

  • confusion

  • sleepiness (fatigue)

  • impaired ability to:

    • remember

    • concentrate

    • pay attention

    • react quickly

  • anxiety, fear or panic

 

Short-term effects on your body can also include:

  • if smoking, damaged blood vessels caused by the smoke

  • decreased blood pressure, which can cause people to faint

  • increased heart rate, which can be dangerous for people with heart conditions and can lead to an increased risk of heart attack

  • Cannabis use can also result in psychotic episodes characterized by:

  • paranoia

  • delusions

  • hallucinations

 

Long-term health effects

 

Long-term effects develop gradually over time, with daily or near-daily (weekly) use that continues over:

  • weeks

  • months

  • years

 

The long-term effects of cannabis on your brain can include an increased risk of addiction. Long-term cannabis use can also harm your:

 

Effects appear to be worse if you:

 

These effects can last from several days to months or longer after you stop using cannabis. They may not be fully reversible even when cannabis use stops.

 

Other long-term effects of smoking cannabis are similar to the effects of smoking tobacco. These effects can include risks to lung health, such as:

  • bronchitis

  • lung infections

  • chronic (long-term) cough

  • increased mucus buildup in the chest

 

Health effects during pregnancy and breastfeeding

 

Just like with tobacco and alcohol, a pregnant woman or new mother's use of cannabis can affect her fetus or newborn child.

 

The substances in cannabis are carried through the mother's blood to her fetus during pregnancy. They are passed into the breast milk following birth. This can lead to health problems for the child.

 

Cannabis use during pregnancy can lead to lower birth weight of the baby. It has also been associated with longer-term developmental effects in children and adolescents, such as:

  • decreases in:

    • memory function

    • ability to pay attention

    • reasoning and problem-solving skills

  • hyperactive behaviour

  • increased risk for future substance use
