Cannabis, commonly known as marijuana, is one of the most widely used psychoactive substances in the world. While some people use cannabis for recreational purposes and others for certain medical conditions, it is important to understand that regular or excessive use can have significant effects on both physical and mental health.
According to the United Nations Office on Drugs and Crime (UNODC), approximately 228 million people worldwide used cannabis in 2022, representing a 20% increase over the past decade. Despite its growing popularity, cannabis use is associated with several short-term and long-term health risks.
This guide explains the seven most common side effects of cannabis, discusses its legal status in Pakistan, explores cannabis withdrawal symptoms, and outlines available treatment options for cannabis addiction.
7 Common Cannabis Side Effects
1. Short-Term Memory Impairment
One of the most common side effects of cannabis is difficulty forming new memories and recalling recent events. This occurs because THC (tetrahydrocannabinol), the primary psychoactive compound in cannabis, affects the hippocampus—the part of the brain responsible for learning and memory. Frequent cannabis use may worsen these cognitive effects and interfere with daily activities, academic performance, and work productivity.
2. Altered Judgment and Coordination
Cannabis can slow reaction time, impair coordination, and reduce decision-making abilities. These effects significantly increase the risk of accidents while driving, operating machinery, or performing tasks that require concentration and precision. Users should avoid potentially dangerous activities while under the influence of cannabis.
3. Increased Heart Rate
Shortly after consumption, cannabis often causes a temporary increase in heart rate that may last several hours. While this effect may be harmless for healthy individuals, it can pose serious risks for people with existing heart disease or cardiovascular conditions. Anyone with heart-related health concerns should consult a healthcare professional before using cannabis.
4. Anxiety and Paranoia
Some individuals experience anxiety, panic attacks, paranoia, or heightened fear after using cannabis, particularly when consuming high-potency products or large doses. These psychological effects are more common among first-time users and individuals with a personal or family history of mental health disorders.
5. Dry Mouth and Dry Eyes
Often referred to as “cottonmouth,” cannabis reduces saliva production, leading to a dry mouth. Users may also experience red, dry, or irritated eyes. Although these symptoms are generally mild, staying hydrated and using lubricating eye drops can help relieve discomfort.
6. Increased Appetite
Commonly known as “the munchies,” cannabis stimulates appetite and may lead to increased food consumption. While this effect can be beneficial for individuals experiencing appetite loss due to certain medical conditions, it may contribute to unwanted weight gain if healthy eating habits are not maintained.
7. Respiratory Problems
Smoking cannabis can irritate the lungs and airways, causing chronic coughing, wheezing, and bronchitis. Long-term smoking may also affect overall lung function. Alternative methods of consumption may reduce respiratory irritation but do not eliminate all potential health risks.
Cannabis in Pakistan
In Pakistan, cannabis is illegal under the Control of Narcotic Substances Act, 1997. Despite legal restrictions, cannabis remains one of the most commonly used illicit substances across the country. Possession, sale, and use of cannabis may result in legal consequences in addition to the physical and psychological risks associated with long-term use.
Cannabis Withdrawal Symptoms
People who use cannabis regularly may develop dependence. When they stop using it, they can experience withdrawal symptoms as the brain adjusts to functioning without THC.
Common withdrawal symptoms include:
- Irritability
- Anxiety
- Sleep disturbances or insomnia
- Reduced appetite
- Mood swings
- Restlessness
- Difficulty concentrating
- Strong cravings for cannabis
Although cannabis withdrawal is generally not life-threatening, professional support can make the recovery process significantly easier and reduce the risk of relapse.
Cannabis Addiction Treatment
Effective treatment for cannabis addiction focuses on addressing both the physical dependence and the underlying psychological factors that contribute to continued use.
Treatment may include:
- Medical assessment and supervised detoxification
- Individual counseling
- Cognitive Behavioral Therapy (CBT)
- Family counseling
- Group therapy
- Relapse prevention planning
- Long-term aftercare and recovery support
