Statistics About Cannabis
🌍 Global and regional statistics
- As of 2023, an estimated 244 million people worldwide reported using cannabis in the past 12 months. That corresponds to about 4.6% of the global population aged 15–64. UNODC+2Statista+2
- Over the past decade, global cannabis use has increased by ~34%. UNODC
- In 2022, global data showed ~228 million cannabis users — reflecting a rising trend. UNODC+1
- The use rates vary greatly by region. For example: Statista+2UNODC+2
- In some regions, adult populations (15–64) have use rates in the “6%–12%” range. UNODC+1
- In the European Union (among 15–34-year-olds), recent-year use is estimated at ≈ 15.4%. EUDA
- Among 15–24-year-olds in that group, cannabis use in the last year is about 18.6%, and about 10.1% used it in the last month. EUDA
- Among adults (15–64) in the EU, about 1.5% (≈ 4.3 million people) are “daily or almost daily” cannabis users (i.e. 20+ days a month). EUDA+1
- Use tends to be more common among men than women. For example, globally in 2023 cannabis use among 15–64-year-old men was ~7.0%, while among women it was ~2.3%. UNODC+1
⚠️ Health-use disorder and treatment data
- According to the 2025 global drug report, ~42% of all drug-use disorder cases worldwide are related to cannabis use disorders. UNODC
- In many regions, cannabis remains the leading drug for which people seek treatment: e.g. 37% of people in treatment in Oceania, 32% in Africa. UNODC
- In the United States (2021 data), about 52.5 million people — roughly 19% of Americans — reported using cannabis at least once. Hastalık Kontrol ve Önleme Merkezleri
- Among those who use cannabis, studies estimate ~3 in 10 people may meet criteria for Cannabis Use Disorder (i.e. problematic or dependent use). Hastalık Kontrol ve Önleme Merkezleri
📈 Trends and Observations
- Use is rising: from 228 million in 2022 to 244 million in 2023. UNODC+1
- Cannabis remains the most commonly used illicit drug globally. UNODC+1
- While prevalence varies by age and region, younger age groups (teens, 20s, 30s) often show higher rates of use. EUDA+2PubMed+2
📊 What This Data Suggests (Trends & Patterns)
- Cannabis use is growing globally, both in absolute numbers and as a share of population.
- Younger people tend to have higher use rates compared with general adult population (e.g. youth 15–24 or 15–34 vs. 15–64).
- A small but significant portion of users smoke regularly (daily or almost daily) — which may increase risk of dependence or health issues.
- A large fraction of global drug-use disorders are linked to cannabis — so while many users might use casually, there is a non-negligible burden of problematic use.
- The rising potency of cannabis could influence health risks, making even occasional use potentially stronger than in the past.
What Are the Risks of Cannabis?
Cannabis has both therapeutic uses and potential dangers. The risks depend on how often, how much, how early and how it is consumed (smoking, vaping, edibles).
Here are the main risks, explained clearly:
1. Mental Health Risks
• Anxiety & Panic Attacks
High-THC strains can trigger sudden anxiety, paranoia or panic, especially in new or sensitive users.
• Psychosis Risk
Heavy or frequent use can increase the risk of psychosis, especially in people with a family history of schizophrenia or bipolar disorder.
• Depression & Motivation Decline
Regular use may worsen depression symptoms and cause amotivation (low drive, low productivity).
2. Addiction & Dependence
Cannabis can be addictive.
- About 3 in 10 people who use cannabis may develop Cannabis Use Disorder (CUD).
- Daily users have the highest risk.
- Symptoms include craving, needing stronger doses and difficulty cutting down.
3. Cognitive & Brain Function Effects
• Memory Problems
THC affects short-term memory and attention. Regular use can make studying or focusing harder.
• Learning & Concentration Issues
Chronic use (especially starting young) may reduce cognitive performance.
• Teenage Brain Vulnerability
Using cannabis before age 21 is linked to stronger negative effects because the brain is still developing.
4. Respiratory Risks (When Smoked)
Smoking cannabis exposes the lungs to heat and chemicals.
Possible effects:
- Chronic cough
- Wheezing
- Increased phlegm
- Bronchitis symptoms
- Irritation of airways
While cannabis smoke contains fewer toxins than tobacco, it still irritates and inflames the lungs.
(Note: Vaping reduces smoke exposure but introduces other risks, like chemical inhalation.)
5. Impaired Driving
Cannabis slows reaction times and affects coordination.
- After using cannabis, the risk of traffic accidents increases by 2–3×.
- THC impairment lasts 4–8 hours, depending on dose.
6. Increased Heart Rate
Cannabis temporarily raises heart rate and can strain the cardiovascular system.
Higher risk is seen in:
- older adults
- people with heart disease
Some studies show increased risk of heart events shortly after heavy THC exposure.
7. Impact on Sleep
Many use cannabis to sleep but in long-term:
- It can reduce REM sleep
- Dependence can disturb natural sleep cycles
- Withdrawal often causes insomnia or vivid dreams
8. Pregnancy and Child Development Risks
Using cannabis while pregnant may cause to:
- Low birth weight
- Attention and behavior problems in children
- Possible developmental delays
THC crosses the placenta and is stored in fetal tissues.
9. Cannabinoid Hyperemesis Syndrome (CHS)
A rare but increasing condition among heavy users, causing:
- Severe nausea
- Vomiting cycles
- Relief from hot showers (a key symptom)
It usually stops only after quitting cannabis.
10. Contaminants & Black-Market Risks
Illegally sold cannabis may contain:
- Pesticides
- Mold
- Heavy metals
- Synthetic cannabinoids
These can cause dangerous reactions.

What Are the Benefits of Cannabis?
Cannabis has several potential medical and therapeutic benefits, mostly due to two key compounds:
- THC — provides pain relief, appetite stimulation and relaxation
- CBD — offers anti-inflammatory, anti-anxiety and anti-seizure effects without causing a “high”
Below are the most widely recognized benefits:
1. Pain Relief (Chronic Pain)
Cannabis is commonly used for neuropathic pain, arthritis pain, migraine and back pain.
- Helps reduce pain signals in the nervous system
- Often used by patients who don’t respond well to opioids or want a safer alternative
2. Reduces Inflammation
CBD is known for its anti-inflammatory effects.
Useful for:
- arthritis
- inflammatory bowel disease (IBD)
- autoimmune conditions
- muscle recovery
3. Helps with Anxiety & Stress
Many people use cannabis (especially CBD-dominant strains) to:
- Relax
- Reduce stress
- Improve mood
High-THC can increase anxiety for some people but CBD tends to reduce it.
4. Improves Sleep
Cannabis may help with:
- Falling asleep faster
- Reducing nighttime awakenings
- Managing insomnia
- Calming a racing mind
But long-term daily use may disrupt sleep cycles.
5. Appetite Stimulation
THC increases hunger.
Helpful for:
- cancer patients undergoing chemotherapy
- people with HIV/AIDS
- severe appetite loss due to illness
It can help people avoid dangerous weight loss.
6. Nausea & Vomiting Control
THC is used medically to reduce nausea, especially:
- chemotherapy-induced nausea
- nausea from chronic illnesses
Certain pharmaceutical THC products (like dronabinol) are FDA-approved for this purpose.
7. Seizure Reduction
CBD (especially medical-grade) is beneficial for epilepsy.
- Studies show CBD can reduce seizures in rare conditions like Dravet syndrome and Lennox-Gastaut syndrome
- Leads to fewer and less severe seizures
8. Muscle Relaxation & Spasm Relief
Helpful for conditions like:
- multiple sclerosis (MS)
- spinal cord injuries
- muscle spasticity
Cannabis can ease muscle stiffness and reduce cramps.
9. Neuroprotective Potential
Some early research suggests cannabis compounds may protect brain cells and reduce inflammation in neurological disorders such as:
- Parkinson’s disease
- Alzheimer’s disease
- Multiple sclerosis
More research is needed.
10. Mood Improvement & Creativity
Recreational users often report:
- enhanced mood
- increased creativity
- improved sensory perception
- deeper relaxation
These effects change acording to strain and dose.
11. Possible Benefits for PTSD
Some studies show cannabis can:
- reduce nightmares
- ease hypervigilance
- calm anxiety spikes
CBD appears to help regulate the stress response system.
12. Harm Reduction Compared to Other Substances
For some people, cannabis can be a safer alternative to:
- alcohol
- opioids
- benzodiazepines
CBD and low-THC cannabis have low risk of overdose and lower addiction potential.
Key Point to Remember
Cannabis benefits depend on:
- the dose
- the THC/CBD ratio
- the method of use (smoking vs. vaporizing vs. edibles)
- individual sensitivity
While cannabis has real medical and wellness benefits, it also has risks — especially with heavy or early-age use.
