Cannabis Rehab & Cannabis Detox

Before cannabis detox can begin, it is important to understand the effects and risks associated with the drug.


Cannabis is the most widely used illegal drug in the UK. It is a depressant and slows the body down. It grows naturally as a plant and is usually smoked, either when mixed with tobacco or in a bong. However, it can also be mixed into food, such as cakes or biscuits.

The main ingredient of cannabis is THC, which has the effect of making the user feel happy and relaxed. It can also create hallucinations. Other effects include being overly aware of your senses, focusing on individual objects and even getting the sense of time slowing down.


There are myths that cannabis is safe because it is naturally occurring. However, there are many risks associated with taking cannabis. These can include:

  • Paranoia – Cannabis use can result in feelings of anxiety, suspicion, panic, and paranoia.
  • Concentration – Cannabis use can affect how the brain works. It makes it difficult to learn, concentrate and stay motivated with many users adopting a lazier lifestyle. This is particularly dangerous in younger people as their brains have not fully developed.
  • Cancer – Smoking cannabis can lead to lung and throat cancer. The risk is even greater when mixed with tobacco.
  • Nausea – Often known as a “whitey”, some users become light-headed and sick after smoking cannabis.
  • Mental illness – There is a close link between regular cannabis use and the development of psychotic illnesses like schizophrenia. The risk is increased if there is a family history of mental illness in the family. Those with schizophrenia already may suffer a relapse when smoking cannabis.

What’s in cannabis that makes it so addictive?

Whilst cannabis is perhaps the most popular drug consumed in the United Kingdom behind alcohol and tobacco, many people are simply not aware of the above risks. Cannabis is a psychoactive drug, containing a substance known as THC. THC binds to cannabinoid receptors located in the brain. When cannabis binds to cannabinoid receptors, users will feel drowsy and calm. It’s these feelings that make cannabis psychologically addictive.

When cannabis users consume cannabis, a tolerance to the drug is built up. This means greater amounts of cannabis must be consumed in order to experience the desired ‘high’. The volume of cannabis will increase, and the user will find him or herself spending greater amounts of both time and money consuming cannabis. Eventually, consuming cannabis becomes a preoccupation, and people who develop a cannabis addiction will begin to neglect other important areas of their lives such as work and family commitments.

Cannabis: a changing drug

The strains of cannabis found on our streets is far removed from the cannabis that was widely available in the 1960s and 1970s when cannabis use first became glamourised in books, TV programmes and movies. Cannabis that was widely available in the 1960s and 1970s was ironically not too harmful to your health.

Shifting forward into the 21st Century, cannabis is much more potent given the advancements in how cannabis is synthesised. The cannabis you are likely to consume today contains around 10 times more THC to what was available 10-20 years ago. This increase in THC content means cannabis is much more likely to result in addiction and the associated problems that arise from a cannabis addiction. An increase in the amount of THC in cannabis does not increase the risk of getting cancer. Instead, more THC increases the risk of developing a cannabis-induced mental health problem, such as anxiety, depression, sleep disorders, psychosis and even schizophrenia.

How cannabis rehab helps

By far the most effective form of treatment for cannabis addiction is to attend a residential rehab clinic. This is exactly what we offer at Cassiobury Court in Watford. We are strategically based to service the entire South East, as well as the Midlands, East Anglia and parts of the South West. During your cannabis rehab programme, you will benefit from effective therapy techniques such as Cognitive Behavioural Therapy, group therapy, holistic therapies, and psychotherapy. You will also sit in workshops where you are educated about the science of cannabis addiction.

One of the most important elements of cannabis rehab is relapse prevention. Here, you will be given the tool-kit and strategies to help you avoid a cannabis relapse. This ensures your long-term recovery is a success. At Cassiobury Court, we are transparent about our cannabis treatment success rates, and we offer structured aftercare sessions to bolster your recovery once you leave our care.

The body requires around three months to completely rid itself of THC, the active chemical in cannabis that’s addictive. This is because THC is fat-soluble, and thus THC is stored inside fat cells until fat is metabolised for everyday energy needs.

Will I experience withdrawal symptoms during a cannabis rehab?

Cannabis is classified as a psychologically addictive drug. Fortunately, it is impossible to develop a physical dependency on alcohol. This means you will not experience physical withdrawal symptoms when you undergo a cannabis detox. However, you will experience psychological withdrawal symptoms that may nevertheless test your resolve to the maximum.

Common psychological withdrawal symptoms that are experienced during a cannabis rehab programme include:

  • Mood swings
  • Trouble getting to sleep
  • Severe depression
  • Migraines
  • Cravings for cannabis

What happens after the conclusion of my cannabis rehab programme?

At Cassiobury Court, treatment does not end when you are discharged from our care. Your discharge merely signifies the end of residential treatment. When this occurs, you will begin the outpatient leg of cannabis treatment. This takes the form of aftercare sessions. You will return to our rehab clinic for weekly aftercare sessions. These sessions typically take the form of group therapy sessions.
