Cannabis (also called marijuana, dagga, or weed) contains many compounds, but the two most well-known are THC (tetrahydrocannabinol), which causes the “high,” and CBD (cannabidiol), which is non-intoxicating and has some medical uses.
Here is a balanced overview of the potential benefits and risks.
Potential Benefits
Some of these benefits are supported by good evidence in specific medical situations, while others have more limited evidence.
- Pain relief: May help some people with chronic pain, especially nerve-related pain.
- Reduces nausea and vomiting: Can help people undergoing chemotherapy.
- Improves appetite: May benefit people with severe weight loss from illnesses such as cancer or HIV/AIDS.
- Muscle spasticity: Can reduce muscle stiffness and spasms in some people with multiple sclerosis.
- Sleep: Some people report improved sleep, particularly if pain is keeping them awake.
- Anxiety: Low doses may reduce anxiety in some individuals, although higher-THC products often have the opposite effect.
- Seizures: Certain prescription CBD medications are approved for treating some rare forms of epilepsy.
Potential Risks
Physical
- Impaired coordination and slower reaction times, making driving or operating machinery dangerous.
- Increased heart rate, which may be risky for people with heart disease.
- Chronic smoking can irritate the lungs, causing coughing and bronchitis-like symptoms.
Mental
- Short-term memory impairment.
- Difficulty concentrating and learning.
- Reduced motivation in some people, particularly with heavy, long-term use.
- Anxiety, panic attacks, or paranoia, especially with high-THC products.
- Increased risk of psychosis in people who are genetically vulnerable or who use high-potency cannabis frequently.
Dependence
- Cannabis can be addictive. About 1 in 10 people who use cannabis develop cannabis use disorder, with the risk increasing when use begins during adolescence or becomes daily.
Effects on Young People
Regular use during adolescence is associated with:
- Problems with attention, memory, and learning.
- Higher risk of developing dependence.
- Increased likelihood of mental health problems in susceptible individuals.
Medical vs. Recreational Use
Medical cannabis is typically prescribed for specific conditions and is used under medical supervision, often with controlled amounts of THC and CBD.
Recreational cannabis is used primarily for its intoxicating effects and may contain much higher THC levels, increasing the risk of unwanted side effects.
What Does the Bible Say?
The Bible does not specifically mention cannabis. However, it teaches principles that are relevant:
- Self-control is a fruit of the Spirit (Galatians 5:22–23).
- Christians are encouraged to have a clear and sober mind (1 Peter 5:8).
- Believers are told not to be mastered by anything (1 Corinthians 6:12).
- Our bodies are described as temples of the Holy Spirit (1 Corinthians 6:19–20).
From a Christian perspective, any substance that impairs judgment, leads to dependence, or weakens self-control should be approached with great caution.
Summary
Potential benefits:
- Pain relief
- Reduced nausea
- Better appetite
- Relief from muscle spasms
- Help with certain seizure disorders (CBD)
- May improve sleep for some people
Potential risks:
- Impaired judgment and coordination
- Memory and concentration problems
- Anxiety, paranoia, or panic
- Risk of addiction
- Lung irritation when smoked
- Possible increased risk of psychosis in vulnerable individuals
- Reduced motivation with heavy long-term use
Whether cannabis is helpful or harmful depends on factors such as the person’s age, health, reason for use, dose, THC content, frequency of use, and method of consumption. For some medical conditions it can be beneficial under medical supervision, while for others—especially frequent recreational use—the risks may outweigh the benefits.
