There’s a bigger question lurking beyond the clichés and stoner stereotypes: Can weed actually influence the way we make decisions or how we differentiate between right and wrong?
It turns out, this isn’t just a high-debate topic. Science is beginning to explore it, and what studies are finding is as hazy as it is fascinating.
The Brain & Cannabis
Let’s start with the basics. Cannabis interacts with the endocannabinoid system, which plays a key role in mood, memory, appetite, and—yes—decision-making. THC, the primary psychoactive compound in cannabis, can temporarily alter how the brain processes information, particularly in areas linked to reward, risk, and self-reflection.
This doesn’t mean that smoking cannabis changes who you are, but it can affect how decisions are made, especially when it comes to impulse control, empathy, or how we interpret consequences.
Think about it: have you ever made a bold decision while high, like texting an ex, having an online shopping spree, or suddenly deciding to start a hydroponic herb garden after you’ve hit the joint? That’s not just the bud talking; that’s THC-induced, altered risk perception and impulse regulation doing their thing.
Risky Business or Chill Logic?
One of the more interesting angles here is the role that cannabis plays in processing risk assessment. Some studies suggest that people under the influence of the good green may take more risks, especially in social or financial situations. Others argue the opposite—that cannabis can make people more cautious, more thoughtful, and less reactive.
So which is it?
Well, it depends on the person, the strain, the dose, and even the environment. Let’s take a look at the upsides and downsides. A heavy indica might slow you down and make you think twice about every choice. It could also create feelings of being “down” or “bleak” if consumed excessively.
On the flip side, a strong sativa might ramp up creativity and confidence, sometimes at the expense of practicality. Certain tokers may experience paranoia from certain sativas, with many people enjoying hybrid strains as the happy medium.
Morality in the Mix
Now, here’s where things get even more interesting: Does cannabis impact our sense of morality?
We’re not talking about whether weed itself is morally right or wrong—that argument’s tired. We’re talking about whether being high shifts our judgment about right and wrong in general.
Some psychologists suggest that cannabis can increase empathy and compassion, which could nudge people toward more prosocial or ethical decisions. You’re more likely to think about how your actions affect others or to see multiple sides of a situation. In that sense, cannabis might make someone more morally aware—or at least more emotionally in tune with the people around them. I think the world could do better if more of us had that perception.
Contrastingly, being under the influence can cause boundaries to become blurry. If someone already struggles with ethical decision-making, cannabis could dampen their internal moral compass further. In legal or high-stakes situations, being impaired could lead to bad judgment calls or even serious consequences.
It’s important for us to realise the responsibility that comes with altered consciousness.
Personal Insight or Mental Maze?
Some users say cannabis helps them connect the dots between past behaviour and present values. It offers space to process emotions, examine motives, or break free from rigid thinking patterns.
Others, though, find themselves going in circles—overanalysing, doubting themselves, or slipping into moral grey areas that feel deeper than they really are.
If you’re naturally introspective, weed might amplify that. If you tend to avoid tough questions, it could either help you face them or help you hide from them even better.
Culture Shapes Perception
In South Africa, where cannabis carries both deep cultural roots and modern stigma, your mindset going into the experience can shape your moral stance while high.
Traditional healers have used cannabis in ritual and spiritual practices for generations, often to enhance intuition or gain insight. In these contexts, moral and personal decisions are part of the journey, not distractions from it.
In urban settings, where cannabis is often still navigating its way through legality and stigma obstacles, the conversation around “good” and “bad” decisions while high can feel more conflicted—especially if someone’s afraid of being judged or caught.
So, context matters.
So, Should You Trust Yourself When You’re High?
That depends. If you’re making decisions that require emotional nuance, deep honesty, or out-of-the-box thinking, cannabis might open some unexpected doors. But if you’re navigating a high-stakes situation, such as signing a contract, having a serious confrontation, or making life-changing choices, it might be smarter to wait until you’re clear-headed.
The key isn’t to fear the shift in perspective that weed can bring—it’s to be aware of it. Recognise that your brain might be processing information differently. Give yourself space to reflect without reacting too quickly. At the very least, allow yourself the opportunity to reflect honestly before you hit the bong.
Final Thought (Not a Moral Lesson)
Cannabis can absolutely influence how we think, feel, and decide. Whether that leads to better decisions, more compassionate reasoning, or a fridge full of cheese you don’t remember buying—that’s part of the journey.
But the next time you’re high and pondering the universe, ask yourself: Am I being honest with myself right now, or am I just really into this idea because I’m vibing?
That little pause might be all the moral clarity you need.
