Cannabis Rehab

At Asana Lodge, we are highly experienced in caring and rehabilitating those with cannabis addictions. Get in touch with us today for help or advice on how to start your journey to recovery and a life that is free from cannabis abuse. We can begin drug rehab treatment as soon as you are able to do so, with no waiting lists.

What is Cannabis?

The ‘high’ caused by cannabis is known to place the user into an extremely calm state of relaxation, which is caused by the chemical tetrahydrocannabinol (THC). Cannabis is extremely addictive and can result in behavioural changes such as mood swings, paranoia and depression.  This is because over time the body becomes familiar with the drug’s effect and becomes dependent on it as a result. The drug can either be smoked or eaten in baked goods, otherwise known as ‘edibles’.

All of our cannabis rehab programmes are completely bespoke and tailored to meet each clients’ individual needs. Your care is our utmost concern, and our sympathetic and understanding staff are here for you at every step of the way.


How Does Cannabis Abuse Affect The Body?

If you abuse cannabis, particularly to the point where it becomes a drug addiction requiring rehab, you may notice physical side effects including an increased desire to eat, euphoric sensations, an overly- calm mood and lack of correct sensory function. This is because the drug can affect your central nervous system and interrupt signals sent by the brain around the body.

Other short-term side effects of cannabis abuse are feeling sick, feeling paranoid, a raised pulse and blood pressure and becoming confused. It is argued by some that cannabis is relatively harmless, but this is far from true, as the drug can be incredibly addictive and lead to long-term mental health issues if it is abused for long periods of time.


Symptoms of A Cannabis Addiction

There are many serious health complications that can arise from cannabis abuse. The drug can affect hormone levels, and create rather severe mood swings in regular users.

Continued use of the drug is required to achieve a desired ‘high’, meaning tolerance to it slowly builds over time, and the user requires more to get the ‘high’ they need. Symptoms of cannabis addiction can be both mental and physical, and are outlined below.

Physical symptoms of cannabis addiction:

  • Anxiety
  • Panic
  • Trouble sleeping
  • Increased aggression
  • Anger
  • Mood swings
  • Irritability
  • Little or no appetite


Psychological and behavioural symptoms of cannabis addiction:

  • Secrecy regarding cannabis use
  • Shortness of temper
  • Paranoia
  • Depression


Cannabis Rehab at Asana Lodge

If you choose rehabilitation for cannabis misuse at Asana Lodge, treatment options available to you include:

Cannabis Detox: Whilst withdrawing from cannabis, you are closely supervised by medical professionals and may be given medications to reduce withdrawal symptoms and ease any mental health issues that may arise as a result, such as panic, anxiety or depression.

Rehab: Those who wish to stay with us in residential rehab will have round-the-clock care and support from our team. You will undertake therapies involving various forms of counselling, mindfulness and spiritual techniques to tackle the cause of your addiction and change the way you approach drugs like cannabis.

During your stay with us, you will also have the opportunity to join in group therapy sessions, in which you can speak to those who have had similar experiences with cannabis. You’ll also attend educational programmes, mindfulness and activity classes, psycho-educational workshops and creative therapy groups, such as art therapy.

If you think you have a cannabis addiction, we can help at Asana Lodge. Get in touch with us today for a free assessment, so we can help you get your life back and break away from the consuming cycle of cannabis addiction. Many of our staff have first-hand experience of addiction therapy and rehab, and understand our clients’ needs and concerns.



Unfortunately it is not uncommon for individuals to relapse after they leave rehab for addiction. The first 12 months of leaving rehab will be the hardest and this is the time that most will relapse to some degree.

Whilst you are at rehab, you are being provided with the necessary skills to manage all the daily factors and stressors that could set of your addiction. But putting them into practice when you return to your daily life requires willpower and support at first to give you the best chance at succeeding in an addiction-free life. Here at Asana Lodge we are there with you every step of the way and offer a 12month aftercare package to ensure you have all the support you need once you leave our rehab.

Contact Us Today

We can give you the guidance you need to overcome them for good.
