Why do people smoke weed?

A partner asks, half joking, why you need it every night. A friend who stopped asks if you've ever thought about it. And the honest answer that comes out is something like it just helps. If you'd like support, we offer cannabis addiction treatment in Kitchener-Waterloo, in person or online anywhere in Ontario.

This article looks at the most common reasons people use cannabis, what cannabis does in the brain, when those reasons start to shift, and how to get curious about your own. If you're wondering whether your own use is a lot, our article on what is considered heavy cannabis use looks at frequency and strength.

Why do people use cannabis?

There's rarely one reason. Most people have a mix, and the mix changes over time. Since legalization in Canada, recreational cannabis has become easier to buy and easier to talk about, so more people are asking the question out loud. When people ask why do people smoke marijuana, the answers tend to fall into three groups:

• Feeling good: enjoyment, laughter and the high itself.
• Feeling better: easing stress, a low mood or a racing mind.
• Fitting in: being part of a group, a ritual or a shared way of unwinding.

None of these reasons is wrong. They're human. What matters is how well cannabis is meeting them, and what it costs your health along the way.

To relax and take the edge off

For many people, cannabis is the way the day ends. The job is done, the house is finally quiet, and cannabis signals that it's time to stop.

• Relaxation after a long or tense day.
• Stress relief when the mind keeps replaying things.
• A clear line between "on" and "off".

That kind of calm is real, and it's a big part of why cannabis can feel so hard to give up. The need underneath it, to rest and switch off, is good for your health.

For fun, curiosity and feeling good

Some people start out of curiosity and keep going because it's enjoyable. A cannabis high can bring euphoria, laughter and a sense that everything slows down.

• Pleasure and a lighter outlook.
• Music, food and films that feel more vivid.
• A sense of creativity or new ideas.

Getting high can simply be fun, especially with friends or on a day off. For plenty of people that's where it stays, and smoking weed is an occasional thing rather than a daily one.

To connect with other people

Cannabis is often social. Passing a joint, sharing an edible or sitting on a balcony with friends can feel like belonging.

• Socializing and feeling more at ease in a group.
• Bonding with a partner or old friends.
• Friendships that grew up around cannabis.
• Peer pressure, or simply not wanting to be the one who says no.

Some people also use cannabis in spiritual or ceremonial settings, where it carries meaning beyond getting stoned.

To cope with hard emotions

This is one of the most common reasons, and the one people talk about least. Cannabis can quiet anxiety, soften sadness or make a painful memory feel further away. You might notice you reach for it after a hard conversation more than after a good day.

• Coping with grief, loneliness or a heavy week.
• Calming anxiety or a busy, worried mind.
• Lifting depression or numbing feelings that are hard to sit with.
• Emotion regulation when nothing else seems to help.

Using cannabis this way makes sense. The trouble is that the calm tends to be short, and the emotions are usually still waiting the next day. Over time, that can wear on your mental health.

For sleep, appetite and physical discomfort

Some people use cannabis to fall asleep, to bring back their appetite or to ease pain. Others use it for medical reasons with a prescription, which is a conversation to have with a doctor about your health.

• Sleep that comes more easily, at least at first.
• Appetite when eating feels hard.
• Easing aches or tension at the end of the day.

These reasons often blend with emotional ones. Poor rest, for example, is often tied to worry, and cannabis can end up holding both.

Out of boredom and routine

Sometimes the reason isn't deep at all. Cannabis fills an empty evening, makes chores more bearable or simply becomes what happens at a certain time of day. Over months, the cannabis routine can run on its own, even when you'd rather be doing something else.

What weed does in the brain

THC, the main active part of cannabis, acts on the reward system. It nudges up dopamine, the chemical linked with enjoyment and motivation, which is part of why weed feels good and why you want it again. The short-term effects of THC can include calm, a shift in how time feels, stronger hunger and a brighter outlook.

Other effects vary from person to person and from product to product, depending on how much THC is in it. Over time, the brain adjusts to regular use. That's why the same amount often does less, and why the effects people chase can slowly become harder to reach.

When the reasons start to shift

For many people, cannabis use stays steady. For others, the reason changes quietly. It starts as enjoyment or comfort and becomes something you need to feel normal. This often shows up as using to avoid feeling bad rather than to feel good.

• Tolerance builds, so you need more cannabis for the same effects.
• Comfort replaces the effects you used to enjoy.
• Health risks become easier to ignore.

There are other risks too. Some people feel more paranoia or anxiety with strong THC products. And for a smaller number of people, especially those with a family history of psychosis or mental illness, frequent use of strong cannabis can raise the risk of psychosis. Public health guidance in Canada is clear that daily use of high-THC products carries the most risk to mental and physical health. If you have health worries, a doctor is a good place to start.

How everyday use can become cannabis dependency

Dependence doesn't happen overnight. When cannabis is the main way you relax, cope or rest, your body and mind start to rely on it, and that's how cannabis dependency usually builds. Surveys of cannabis users often find that people who use most days notice this most. When they skip a day, they may feel:

• Anxiety, restlessness or irritability.
• Cravings that are hard to ignore.
• A harder time falling asleep or eating.

These are signs of withdrawal, and they're your body adjusting. They don't mean something is wrong with you, and they tend to pass with time and support.

Getting curious about your own reasons

You don't need to decide anything right away. It can help to get curious first:

• What am I usually going through just before I use cannabis?
• What would I have to face if I didn't use cannabis tonight?
• Is it still enjoyable, or mostly a way to get by?
• How is it touching my relationships, my work or my health?
• Would cutting back feel like a loss, or a relief?

The answers can be surprising. For some people, the reason is a busy, restless mind. Our next article on cannabis and ADHD looks at that pattern.

How therapy can help

In therapy, we can look together at what cannabis is doing for you and what you need underneath it, whether that's rest, connection, calm or a break from hard days. Then we can find other ways to meet those needs, at your pace. Counselling isn't about judging your use or forcing a decision. It's about support for your mental health, so cannabis becomes a choice rather than the only option you have.
