Although the research referenced earlier suggests that results can be rapid, you should remember that this is not necessarily the case for all people due to the differences in our digestive and metabolic systems.
Dosing is also paramount, you may need more or less again depending on how your body reacts and processes the CBD. Equally, the type of CBD and the delivery method you choose will also shorten or lengthen the time required for the CBD to enter your system.
Whatever you decide, monitor your usage of CBD and its effect on you, and do not hesitate to consult a doctor if you encounter any serious adverse effects.
If you are suffering from an acute illness we would always advise taking professional medical advice from a physician who is also qualified to advise on CBD.
