Cannabis Addiction | Signs, Symptoms & Effects

Cannabis is one of the most popular drugs in the world, and the chances are that you know someone who smokes it.

Almost 8% of people in the UK reported using cannabis in 2020. Cannabis-related hospitalisations rose more than 50% between 2013 and 2018, as cannabis addiction can creep in while people still think they are in control of their intake. By learning to recognise the signs and risks of cannabis addiction, you will be well-equipped to take the first steps toward recovery.

What Is cannabis addiction?

Cannabis addiction involves the compulsive use of cannabis despite any negative consequences it may have. The drug is made from the psychoactive parts of cannabis plants, which can create feelings of relaxation. You may feel like you have to smoke it to get through the day or become stressed out when you don’t have any. Continuing to smoke even though it impacts negatively on your life is a sign of cannabis addiction.

What are the long-term effects of cannabis addiction?

MRI scans have shown changes in the grey and white matter and connectivity in the brains of people suffering from cannabis addiction. These alterations involve brain areas that help you carry out tasks. Some studies have found these changes to persist even after cannabis use has stopped.

Cannabis addiction can permanently affect how well you think and concentrate. It affects short-term memory, making you forgetful while also affecting your motivation. Sleep problems are common, alongside losing appetite, feeling tired and irritable and experiencing mood swings. Long-term use can lead to low energy, low self-esteem and dissatisfaction with life.

Cannabis smoke contains many of the same cancer-causing chemicals as tobacco. Long-term use carries the risk of chronic obstructive pulmonary disease and respiratory cancers.

Smoking cannabis with tobacco puts you at risk of becoming addicted to nicotine, compounding the difficulties you may face when trying to quit alone.

Cannabis addiction and mental health

Memory loss, anxiety, and panic attacks are common results of cannabis addiction.

Most cannabis sold illegally in the UK is a strong kind known as skunk, linked to a higher risk of mental health episodes. Heavy, regular use of skunk can cause short-lived paranoia severe enough to require hospital treatment. It can also send you into a psychotic state.

Cannabis increases your risk of developing mental illness, especially if you use it at a young age.
