Cannabis NHS: What You Need to Know About Cannabis NHS: What You Need to Know About
Some articles have positive headlines and negative comments, but most people believe the NHS is either giving away cannabis like candy or banning its use entirely. In fact, the reality is somewhere in-between.

Although medical cannabis is available in the UK, there is only limited availability of it to be prescribed by the NHS and only in specific clinical cases under the direction of specialist doctors. A major concern for the NHS in terms of the prescription of medical cannabis is the current lack of strong evidence regarding both short- and long-term safety for many of the other potential uses of medical cannabis. Therefore, prescriptions have been limited as a result of this lack of strong evidence.

Cannabis Side Effects: What the NHS Actually Lists

Some of these side effects may be mild and temporary, but others can be serious and require medical attention.
Possible Side Effect (Examples Listed by the NHS) What it Feels Like What to Do
Dizziness / Feeling Very Tired Feeling Light-Headed, Having a “Foggy” Head, Extreme Fatigue Don’t Drive. Rest. See A Doctor If it Continues.
Mood / Behavioral Change Being Irritable, Feeling Down, Having Emotional “Off Days.” Stop Using the Cannabis and Seek Medical Attention Immediately If This Is New Or Worse Than Before
Feel High / Hallucinations Experiencing Unwanted Intoxication, Paranoid Feelings / Perceptual Distortions Get Immediate Help If Severe. Don’t Ignore This Symptom
Nausea / Diarrhea / Reduced Appetite Stomach Issues. Changes to Appetite Hydrate. Keep An Eye On Things. Contact Your Clinician If the Problem Persists
Suicidal Thoughts Having Dark, Intrusive Thoughts Urgent Assistance Required. Consider This an Emergency

Cannabis Side Effects NHS: What Really Matters

Unfortunately, much of the “unnecessary risk” associated with unregulated products comes from the fact that many people do not know what is in the product they are consuming, and therefore there is no one to hold accountable. In a number of instances, the NHS references the importance of regulating and monitoring the quality of the medical cannabis prescribed and used.

Online advertising, private clinics, social media, and online retail stores tend to operate at a speed far greater than their regulatory counterparts, and create a distorted view of what is available to the general public. What people see advertised, or read about on-line does not necessarily equate to NHS endorsement. To be accepted into clinical pathways for the NHS, medications (including medical cannabis) must meet three criteria, including standardized dosing, pharmaceutical-grade consistency, and peer reviewed evidence; none of these criteria have been met by many of the products currently marketed on-line.

Another critical distinction is between legality and routine prescribing. Legal status alone does not indicate widespread adoption into first line treatment pathways.

Finally, many patients approach cannabis as a “natural” alternative, and therefore fail to realize the necessity of dose control, potential for drug interactions, and the need for regular monitoring.

A Balanced Takeaway

Cannabis is neither a cartoon villain nor a magic cure-all. It is a complex medication with real positive and negative effects – which is exactly why the NHS takes such caution when prescribing medical cannabis.
