Cannabis and mental health

With cannabis use now legal for personal use in South Africa, many people assume it carries little risk to mental health. The reality is more nuanced, and it's worth understanding before, or while, you use it.

What it is

Cannabis affects the brain's chemistry, and while many people use it without significant problems, it can affect mental health differently depending on the person, the frequency of use, and individual vulnerability. Research consistently shows that regular, heavy use, especially starting at a young age, is associated with a higher risk of anxiety, low mood and, in some individuals, more serious mental health difficulties. For people with a personal or family history of certain mental health conditions, the risks can be higher. As with alcohol, using cannabis to cope with stress or difficult emotions is worth paying attention to.

Signs to notice

• Using cannabis to manage stress, anxiety or low mood rather than for occasional enjoyment
• Increasing frequency or amount needed to feel the same effect
• Anxiety, paranoia or low motivation that seems to track with use
• Withdrawal from responsibilities, relationships or activities
• Difficulty cutting down despite wanting to
• Noticeable changes in memory, concentration or mood over time

What helps

• Be honest with yourself about why and how often you're using
• Notice any changes in mood, motivation or anxiety over time
• Take breaks from use to see how you feel without it
• Avoid using cannabis to cope with stress, grief or difficult emotions
• Be especially cautious if you have a personal or family history of mental health conditions
• Talk openly with a professional if you have concerns, rather than guessing

When to reach out for help

Reach out to a professional if cannabis use is affecting your motivation, mood, relationships or daily functioning, if you're struggling to cut down, or if you notice new or worsening anxiety, paranoia or low mood. A professional can assess your situation and advise on what's right for you.
