It's no secret that cannabis is the most widespread illegal drug in the UK.
Many of them cite positive substances as a feeling of relaxation and satisfaction, while some may experience the fit of giggles or become more curious as a result of smoking cannabis.
There are also health benefits, which are now recognized by law, which allow certain individuals to receive the substance.
Despite its popularity, however, there are a whole range of drug-related health risks – as illustrated by the NHS.
These include anxiety or paranoid and cardiovascular diseases, as well as fertility problems.
Health experts also warn about 10% of regular cannabis users who become drug-dependent, with withdrawal symptoms that offer additional health problems.
So, under what circumstances cannabis is legal? What does the NHS say about drugs?
Is it legal?
While cannabis is generally an illegal drug in the UK, there are some cases where its use is in line with the law – for medical purposes.
Although not available for most patients, the Interior Ministry announced in November 2018 that it would become legal for the NHS to provide cannabis-based medicines.
Those who suffer from epilepsy, nausea, and chronic pain due to chemotherapy may be prescribed, although only "very few patients" will likely receive such treatment.
In order to prescribe medical marijuana, the patient must refer his general practitioner to a specialist doctor who has the authority to recommend and approve such treatments.
The specialist will first discuss all other treatment options before considering a cannabis product that should be given only after all other treatments have failed or are considered inadequate.
The NHS confirmed that: "Tests are underway to test cannabis-based drugs for other conditions [but] we will not know if these treatments are effective until the examinations are completed. "
This includes conditions such as cancer pain, glaucoma of eye disease, and loss of appetite in people with HIV or AIDS.
What else does the NHS say?
As well as recognizing the potential medical benefits of such a drug, the NHS also warns the public about health risks.
These include psychotic diseases, lung problems, and fertility problems – all of which are particularly related to long-term use.
The NHS warns that the regular use of cannabis can have some pretty harmful effects, including an increased risk of developing a psychotic illness – such as schizophrenia.
He notes that psychotic illness often involves hallucinations and misconceptions, and is therefore a particularly unpleasant consequence of the drug.
"Cannabis also increases the risk of relapse in people who already have schizophrenia and can exacerbate psychotic symptoms," NHS added.
The health authority also found that smoking cannabis regularly significantly increased the possibility of developing bronchitis – irritation and inflammation of the lungs.
It further explains that, like tobacco smoke, cannabis smoke "contains chemicals that cause cancer," but admits that "it's unclear whether this increases the risk of cancer."
Those who mix tobacco are also at risk of getting diseases such as lung cancer and chronic pulmonary obstructive disease (COPD).
Studies have shown that cannabis can cause fertility problems, as well as problems during pregnancy.
Studies involving animals, for example, have shown that the drug can be mixed with male sperm production and ovulation in females, the NHS explained.
There is also evidence that the use of cannabis regularly during pregnancy can affect the brain's development of the baby, and the combination of the drug with tobacco increases the risk of premature birth.
Those who regularly smoke cannabis over a longer period of time also increase their chances of developing cardiovascular disease – such as heart attacks and strokes.
According to the NHS, it is the cannabis smoke that increases this risk – not the active ingredients in the plant itself.
