What is it?
Cannabis is the scientific name for the hemp plant. Its leaves and flowers contain THC, a psychoactive resin (a sticky gum). THC affects how we think, feel and act.
Cannabis may come as
- dried leaves and flowers or ‘buds’
- pressed resin from flowers and leaves (hashish or hash)
- and concentrated resin extracted with a solvent (hash oil).
Cannabis is usually smoked, but it can also be vaporized into a mist. Some people bake the oil into cookies or brownies, or drink in a tea. Others place a drop of a tincture (concentrated liquid) drop under the tongue.
Why do youth use cannabis?
The most common reason young people give for using cannabis and other psychoactive substances is to feel good or have a good time. Youth report that smoking a joint with friends or at a party helps them relax and engage with others. Youth also use substances because they are curious. It is natural to want to explore the world and try new things. Trying cannabis can be a way to explore something new.
Some people use substances to improve their performance. Some youth say cannabis helps them concentrate. They use cannabis to help them concentrate in the same way others use caffeine to be more alert, perform better or keep focused.
Young people may also use substances to feel better. For youth, this is usually to help them cope with pressure. As one young person said, cannabis “helps me relieve stress, manage anger… calms me down, helps me make it through the day.”
How does cannabis affect the health of youth?
We need more research to better understand how cannabis affects the health of children and youth.
Medical use of cannabis
Research has shown that the CBD in cannabis can help relieve the pain, nausea and muscle problems that are a part of serious medical conditions. Cannabis can also improve the appetite of those with weight loss from HIV/AIDS or cancer treatment. It may also provide relief from anxiety and depression for those struggling with chronic illness. Cannabis is not recommended for children and youth except in very rare medical circumstances. Talk to your doctor if you have questions about the medical use of cannabis.
Non-medical use of cannabis
Many people who use cannabis socially say it helps them relax and increases their sense of well-being. On the other hand, some people feel anxious after using cannabis, which can cause them to withdraw from others. They may also have a hard time remembering things for several hours after smoking cannabis. When a young person uses a lot of cannabis everyday, it can negatively affect their quality of life, IQ level, motivation, attention, concentration and life satisfaction.
It is dangerous to drive or take part in high-risk sexual behaviour while under the influence of cannabis. Cannabis smoke contains toxins, so over time, heavy use of cannabis can increase the risk of breathing problems such as coughing and shortness of breath.
Cannabis, especially the kinds high in THC, has been linked to psychotic symptoms or psychosis in a small number of people. They experience thoughts, feelings, sounds or see things (hallucinations), that others around them do not experience. It is difficult to tell what is real and what is not. Psychosis may be thought of as a break with reality. For most people, the symptoms go away as the body metabolizes the active ingredients in cannabis. Their thinking, feeling and perception returns to normal and the symptoms do not return unless cannabis is used again. A small number of people may develop longer lasting psychosis. This usually happens only to those with a family history of serious and persistent mental illness. The younger someone starts using cannabis and the amount and length of time they use can contribute to a set of life conditions that, for this very small group, results in a diagnosis of schizophrenia.
When is using cannabis a problem?
Using cannabis is a problem when it negatively affects the life of your child or the lives of others. Most people do not experience long-term effects from experimenting with or using substances. It is important to remember that the level of risk related to cannabis use differs from person to person and depends on much more than the properties of the drug itself.
The level of risk for cannabis use differs from person to person and depends on factors like:
- starting to use at an early age (young brains are still developing and are more vulnerable to the effects of psychoactive substances)
- how often it is used
- how much it is used and the THC content (the active ingredient in cannabis)
- their personal health history
- when and why they use the drug
- what they're doing when they use (driving, using other drugs, etc.)
A young person may think it is fun to use cannabis every day or smoking a lot of cannabis at a party. But this can result in less contact with others, increase poor decision making or have other negative health effects. Visit Foundry’s website for more information on the health effects of cannabis.
Cannabis may help ease anxiety or stress if it is only used one in a while. But, like alcohol, if it is used more regularly, or the amount of cannabis being used increases, the chance of harm increases.
It is dangerous to drive while under the influence of cannabis. If the police stop someone and find they are diving while impaired, they can fine that person, suspend their driver's license or bring criminal charges against them.
It is important to help young people think about the pros and cons of using cannabis so they can decide if it is something they really want to do. Please visit Foundry's website for tips on reducing the risk of harm from cannabis use.
