Is Weed Legal in the UK?

There can be a sense of confusion around UK cannabis laws. In this article, we will look at the issues surrounding the legal status of the drug and answer the question, ‘Is cannabis legal in the UK?’

 

Is Weed Legal in the UK?

The short answer is no, the recreational use of cannabis – commonly known as weed – is not currently legal in the UK.

There are some areas that muddy the waters, however.

Firstly, limited medical cannabis use is legal under specific circumstances. It is not commonly prescribed on the NHS though and only for certain conditions, such as chronic pain or anxiety.

Secondly, products containing cannabidiol (CBD) can also be legally used in the UK. CBD is a non-psychoactive compound derived from the cannabis plant and does not provide the ‘high’ generally associated with weed or cannabis use.

Essentially, legality depends on the purpose, source and prescription status of any cannabis that is used.

 

What Does UK Law Say About Cannabis?

The main law dealing with the use of cannabis in the UK is the Misuse of Drugs Act 1971. This is the primary law dealing with controlled drugs in the UK, and it covers cannabis along with many other substances.

Cannabis Classification

The Misuse of Drugs Act 1971 divides prohibited substances into three main categories – Class A, Class B and Class C. Newly emerging drugs such as synthetic cannabinoids and other ‘designer drugs’ can also be prohibited under a temporary banning order while it is decided how these substances should be classified.

Cannabis is currently categorised as a Class B drug in the UK.

In general terms, Class A drugs are considered the most potentially harmful and possession and supply of these drugs tends can carry a higher sentence. The maximum sentences for possessing a Class A drug can be up to 7 years in prison, an unlimited fine or both. The maximum penalty for supply and production can include life in prison.

This does not mean that Class B and Class C drugs are safe and potential sentences associated with them can also be high.

Possession

You can be charged with possessing an illegal substance if you’re caught with cannabis, whether it is yours or not.

The maximum sentence for possessing a Class B drug like cannabis is up to 5 years in prison, an unlimited fine or both.

In practise, the penalties can depend on a wide range of circumstances. Possible police responses including warnings, community resolutions, penalty notices where applicable and prosecution.

A first offence for possession of cannabis is likely to result in a warning or a penalty notice for disorder, but any aggravating factors are likely to lead to an arrest and prosecution.

The maximum sentence on conviction for possession in a magistrates’ court is a penalty of 3 months imprisonment and/or a fine of up to £2,500, with the sentences rising to a maximum of 5 years and an unlimited fine if tried in Crown Court.

Supplying or Producing Cannabis

Supplying, producing or cultivating cannabis is treated far more seriously and is almost always prosecuted, with potentially severe penalties.

Producing and supplying (or intent to supply) a Class B drug like cannabis carries a maximum sentence of up to 14 years in prison, an unlimited fine or both.

 

Is Medical Cannabis Legal?

The Misuse of Drugs Regulations 2001 allow for the legitimate use of some controlled drugs for medical purposes. These regulations were updated in 2018 to allow cannabis-based medicines to be prescribed to patients by specialist doctors.

It is very rare to get a prescription on the NHS and they are generally only available for a very limited range of conditions including certain severe forms of epilepsy, multiple sclerosis (MS) and nausea and vomiting associated with chemotherapy.

Under medical cannabis UK rules, private clinics can also prescribe cannabis products for a wider range of conditions, including chronic pain, anxiety and PTSD. NHS doctors can prescribe cannabis-based medicines for ‘off label’ use but this is even rarer and they must make submit a special application.

It’s also worth noting that medical cannabis can be prescribed in a number of formats, including tinctures, capsules, sprays and dried flowers for vaporisation. It is not available as regular ‘weed’ that can be smoked.

 

Is CBD Legal in the UK?

CBD, or cannabidiol, is a naturally occurring compound found in the cannabis plant. It is found alongside tetrahydrocannabinol (THC), the other key compound in cannabis which causes users to get high.

CBD has no psychoactive properties and CBD products are legal as long as they meet relevant UK regulatory requirements and contain only permitted trace levels of THC.

While CBD does not produce a high, it is claimed that it can hep some people with issues such as anxiety and provide limited pain and stress relief. However, research is ongoing. CBD can cause side effects including nausea, fatigue and irritability. Other potential safety issues are being investigated and consumers should only buy CBD products from reputable retailers.

 

Common Misconceptions About Cannabis Laws

Here are some common misconceptions and myths about UK cannabis laws…

• “Small amounts are legal.”

Reality: Any amount of recreational or non-prescription medical cannabis is illegal to possess.

• “Police won’t do anything.”

Reality: Police have a certain amount of discretion but can charge any individual caught with cannabis. What happens will often depend on the circumstances but could result in a criminal record and possible penalties.

• “Medical cannabis means anyone can buy weed.”

Reality: Medical cannabis products require a prescription and do not take the form of smokable ‘weed’.

• “Growing one plant is allowed.”

Reality: Even growing a single plant could see you charged with production of a Class B drug, which carries severe potential penalties.

• “CBD and cannabis are the same thing.”

Reality: CBD is a compound found in the cannabis plant but it has no psychoactive properties and will not get you high like the other main ingredient THC.
