Cannabis has been around for ages.
Popular in the 1960’s and still popular today.
Many people think it is harmless: Far from it.
While it’s possession is still illegal the consequences of being found in possession of it may not be as severe as they once were. However, the effects have not changed.
Some people can smoke it once and leave it. Others smoke it regularly with no aftereffects. Some people, due to their genetics, can be seriously affected, even with minimal use.
For many, what starts as once or twice at the weekend can lead to daily use. Sometimes several times a day until it is virtually 24/7.
Cannabis addiction can ruin lives, destroy relationships, jobs and studies. It can also ruin your health.

What is Cannabis?
Cannabis is a psychoactive drug derived from the cannabis plant.
Widely used by people to relieve stress and pain from medical conditions and injuries it will affect your mood, as well as how you perceive those around you.
Cannabis contains a psychoactive compound known by it’s abbreviation: THC (Tetrahydrocannabinol). This affects receptors in your brain. This leads to chemical messaging which produces a high.
Cannabis comes in many forms. You can smoke it or eat it in a cookie. However, it matters not how you take it, the effects are the same and dangerous.
What is Cannabis Addiction?
If you smoke cannabis frequently enough, just as with any other drug, prescription medicine, alcohol and caffeine, your brain will start to make adjustments due to it’s presence.
Your brain will develop what is known as tolerance. This means that you will need ever increasing amounts to have the same effect as the amount you took when you first started using it.
Eventually, you will spend inordinate amounts of time trying to source cannabis.
While it is not as expensive as other drugs, you will need to fund your habit which could lead you to using money for bills. This can cause significant problems.
The Brains Reward System
While cannabis may not have the same effects as alcohol or opioids on brain receptors, it is in no way harmless.
THC activates the release of dopamine, a naturally occurring feelgood chemical. This means when you consume cannabis you feel good. The brain will adapt meaning that, in time, without using cannabis you will not experience pleasure.
Risk Factors
Research into why some people are more acutely affected by cannabis is ongoing..
What is known, at this time is:
- Early exposure: The earlier you first use the more likely it is to be problematic
- Genetic predisposition: Those with family members who have addiction issues are more prone to addiction.
- High THC levels: Chemically enhanced cannabis with abnormally high THC levels lead to more cases of addiction
- Mental health conditions: Pre existing conditions can be exacerbated by cannabis. Some people use cannabis to self medicate for mental health conditions but are actually making the problem worse.
Key Takeaways
- Cannabis addiction can progress from occasional use to daily dependence, impacting health and relationships.
- THC, the psychoactive component of cannabis, leads to tolerance and changes in brain chemistry, causing withdrawal symptoms without use.
- Cannabis addiction presents unique risk factors like early exposure and genetic predisposition, worsening mental health conditions.
- Signs of cannabis addiction include neglecting responsibilities, behavioral changes, and a focus on obtaining and using the substance.
- Effective recovery combines therapy, relapse prevention, and aftercare, though no detox exists for cannabis addiction.
Signs and Symptoms of Cannabis Addiction
Being able to see the signs of cannabis addiction can be difficult, even for an experienced addictions clinician.
Unlike cocaine, alcohol and opioid use, there are no obvious physical signs.
However, cannabis addiction leads to behavioural changes, not just a ferocious appetite after using it!
Someone with an addiction to cannabis is likely to loose interest in work projects and social activities.
The person is likely to stop taking care of their responsibilities. Their focus will be on using. It will also take up a lot of their time.

The Impact on Mental Health
Some people are predisposed to cannabis addiction and some are also pre-determined to develop serious psychiatric conditions when they use cannabis.
While it is common for people to use cannabis to try and relieve the symptoms of their anxiety and stress, the cannabis actually makes it worse.
Within the brain is a system known as the endocannabinoid systems. This plays a crucial role in both regulating emotions as well as cognition.
If you affect this with cannabis serious problems can occur such as schizophrenia and psychosis.
Overcoming Cannabis Addiction
Unlike alcohol and heroin, there is no detox for cannabis. However, adjunctive medication is essential in helping someone to manage withdrawal and craving.
A comprehensive treatment programme, including both group and individual therapy, forms the cornertsone of recovery from cannabis addiction.
Relapse prevention training is also an essential element as is aftercare.
All centres provide a minimum of a years aftercare with a weekly support group as well as telephone check in and a dedicated number to call if you are struggling.
