As professional growers and keen advocates of CBD, you will have noticed our numerous articles flying the green flag wherever we can! We have a passion for explaining the benefits it can bring. Medicinal cannabis has even been labelled as a “miracle plant” and has quickly become a regular dietary supplement for nearly 337,900 Britons – a predicted forecast for 2024. 
Cannabis History 101
Contrary to common belief, cannabis use for medicinal purposes dates back centuries. Cannabis has a long history of utilization as a fibre and seed crop in China for nearly 2000 years.  The ancient Greeks also used cannabis as a remedy to treat inflammation and ear-ache. 
So although it may have been a surprise for some of you when CBD products suddenly appeared on the shelves of popular high street store, Holland & Barrett back in early 2017, CBD has actually been used for hundreds of years all around the globe. However CBD hasn’t been easily accessible compared to now, due to how it has been stigmatised.
Does CBD Expire?
Have you ever wondered after purchasing a tincture bottle of CBD oil, “will this expire?” Well, it all depends on what the product is infused with, which is typically MTC oil and flavoured extracts, dependant on potency and strength. It’s not always straightforward to know which brands can be trusted. With the growth of the industry, many merchants offer questionable products and they all claim to be as reliable or high-quality as the next. And until the Food and Drug Administration (FDA) lays down some solid regulations, there will always be this risk in terms of low-quality product. If you notice your CBD product that’s in a translucent bottle has discoloured once opened, or turned a nice shade of pink, it doesn’t mean it’s expired, but has just reacted to sunlight and has oxidised. Therefore, it is widely known as better practise to package CBD products in UV protected material to prevent this from happening.
The real fact is, CBD oil can go bad, but most CBD products are good for at least 12 months.  However, if you purchased CBD over a year ago and it’s made no use other than making a nice bathroom ornament… you may want to replenish the shelf and start reaping the benefits ASAP.An entire 12 months gives you ample time, especially if you’re using it on a regular basis. An active user with an average sized 30ml tincture taking 2 drops per day, based on a 300mg of CBD would last only 30 days, therefore the product stays well within its sell by date.
So although it technically does expire, CBD that’s past its prime won’t typically spoil, turn rancid, or make you sick; however, it may begin to lose potency once it’s expired. Over time, the CBD can begin to oxidise and break down (and evaporate), making it less effective as compared to when it was fresh.
