Inclusion Criteria:  Male and females aged 18 years old or above. Long COVID diagnosis, confirmed by either GP triage clinic or attendance and assessment by a Long COVID clinic. Self-diagnosed Long COVID will not be included in the study. It is expected that in order to have a coded diagnosis of long Covid, the participant will have undertaken the relevant clinical assessment and investigations as recommended by the NICE guidance on Long COVID. https://www.nice.org.uk/guidance/ng188 Females must be non-pregnant, non-lactating. Proficient in English and have internet access and a mobile phone. Stated willingness to comply with all study procedures and availability for the duration of the study. Provision of signed and dated informed consent form. All male and females of childbearing potential must agree to use highly effective contraception from the time of signing informed consent until 3 months (12 weeks) after the treatment has stopped. Participants using systemically acting hormonal contraception for example the oral contraceptive pill or contraceptive implant should use an additional non-hormonal/reliable barrier method of contraception from the time of signing informed consent until 3 months (12 weeks) after the treatment has stopped.  Exclusion Criteria:  Self-diagnosed Long COVID without relevant assessment and investigation as per clinical guidelines. Serious ongoing medical and/or psychiatric illnesses/disorders that will require active and variable treatment during the trial period. (this will be assessed from clinical history and GP records) Used cannabinoids or a cannabinoid-based medicine within 3 months prior to study Day 1 and unwillingness to abstain from recreational drug use during the study period. Cannabis dependence or any other drug or alcohol dependence within the past two years. Known hypersensitivity to cannabis-based products or any of the excipients in the study drug. Use of any other investigational products within 30 days of screening day. Use of anti-coagulant drugs such as warfarin. History of attempted suicide, bipolar disorder or schizophrenia. History of chronic liver failure or present history of an abnormal liver function (LFT) blood test within the 3 months prior to recruitment. This should be able to be confirmed during the screening process as all participants should have had a liver function blood test as part of the recommended clinical assessment prior to diagnosing Long COVID. If no liver function test is available within 6 months of screening (which is unlikely), participants will be asked if they would agree to having a screening LFT. History of allergy to tree nuts, with no definite previous coconut exposure.
