I'm Natalie and I'd like to find out if 
CBD oil is going to work for me.
I've had anxiety for some time, but I'm a mum to a three-year-old little boy now
so it's something I'd like to see the back of.
There’s a cannabis extract, that’s now so popular that you can buy it in just about
everything from oils and vape liquids to shampoo and make up,
to drinks and even chocolate. 
It’s classed as a supplement and is being sold in shops and online. 
It’s called CBD and at high doses a regulated type is being used in medical studies
and it’s getting some positive results.
It's everywhere, but there's just so much conflicting advice as well.
And there's so much to choose from.
I bought it around two months ago, 
I haven't taken any yet
I'm not 100% sure what I've bought.
I'm not sure how it'll interact with 
anything else I'm on.
I've since been diagnosed with other things.
I've tried a number of prescription drugs, mainly antidepressants.
Nothing was pulling me through.
So you get to a point where you'll 
just try anything.
Especially when it's being advertised as something more natural.
I've looked at a couple of sellers' websites.
They're advertised by milligrams, but also percentage strength.
I'm just not really sure what all the
 different colours mean.
I guess the fundamental questions that I want to know over the next couple of days is:
Will it work for me? Will it work for others?
How will it work? 
What dosage should I be taking?
Should others be taking?
Hi, I'm Natalie. 
 Thanks for showing us around.
That's alright, no problem.
Shall we go and have a look at
 a crop that I planted 10 days ago?
Yeah, let's go up, yeah.
I'm just curious to find out what you grow here, and how it works from your side. 
Well we grow hemp and flax for fibre.
We've got a whole processing plant 
so we can sell clean fibre for
it goes into mattresses 
and loft insulation.
By the beginning of August
hopefully this will be 10ft tall.
I'm sure loads of people are interested; what's the difference between this and
marijuana?
Well hemp and marijuana are
 both cannabis plants
 but you've got different varieties that produce different cannabinoids.
How legal is this, and when does it get to the point where it becomes illegal?
We are perfectly legal because we're licensed by the Home Office to produce hemp straw.
We're not allowed to harvest 
the leaf and flower
so we have to leave the
leaf and flower in the field.
And what do you do with the leaf and flower, do you just leave it here?
It goes to waste.
Right, ok.
So the bit we're throwing away
is the part of the plant that the CBD is being extracted from.
It frustrates me somewhat that all the CBD producing companies in the UK
are allowed to bring leaf and 
flower in from abroad 
but we can't produce it at home.
If the leaves and flowers go to waste
where are all the CBD UK oil coming from?
All the UK produced products, it's either coming from Eastern Europe
or America.
Ok, I didn't realise that.
I imagine most people don't.
Most people don't.
When people hear ‘cannabis’, they usually think ‘getting high’ 
and although CBD is cannabis, it doesn’t 
get you high, and it’s legal.
And that’s because cannabis is actually the name of a group of plants 
and both marijuana and
 hemp belong to that family.
Cannabis plants have around 100 different chemicals in them called cannabinoids
and they can various effects on us.
Marijuana plants have been
 bred to have higher levels 
of a psychoactive chemical 
known as THC.
Whereas hemp plants have higher 
levels of the chemical CBD, 
which is not psychoactive, and can sometimes have pain-relieving and calming effects. 
From my research into the CBD oil I just presumed that it was all made in the UK
from what I’ve read nowhere states differently.  But having learned today that
the local, home grown farmers, can’t even 
use the bits that make the CBD 
it throws you into a little bit of doubt and confusion once again.
I'm Natalie.
I'm Elizabeth.
Nice to meet you.
What have you found out in your 
research so far?
So it's a really exciting area I think 
especially in psychosis because
we don't really have treatments that are as effective as we'd hope and they 
often come along with lots of very 
unpleasant side effects. 
It seems that CBD is relatively 
safe and well tolerated.
So the study that I worked 
on looked at 
people who were at risk 
of developing psychosis
and we gave them a 600mg dose of CBD or a placebo for three weeks.
And we found that CBD
 was able to normalise the
disfunction that you see in certain 
brain areas involved in psychosis.
I haven’t tried it, but I've 
opened it and it stinks.
It smells like soil or something doesn't it?
It's hard to say what it smells like.
I bought this one online and it’s 
2.5mg of CBD per drop, 
but that’s probably not going 
to be very effective
if you’re looking at 300mg or 600mg?
I think the risk here is that we just don't have the evidence of whether it works or not. 
 The research that we know about is looking at sort of quite high doses 
600 to 2000 milligrams and we know that this could have a clinical benefit
but the things that you can get on the high street often they have much lower levels
and we just don't know basically whether 
they work or not. 
I know a lot of people report 
that this is helpful
however it's difficult to know how much of that is because of the drug
or because of a placebo effect.
Often a placebo effect isn't a bad thing.
What would you recommend, what would you advise before purchasing a product online?
I think it's important to speak to your doctor if  you're considering it because the other
thing that we don't know about CBD is the effects that it might have when 
when you're taking another 
medication, for example.
Our bodies are full of receptors 
that react to cannabis.
These receptors are part of an internal system, which helps control our bodily functions, 
such as our appetite, pain relief and 
coping with stress and anxiety.
It’s called the endocannabinoid system, or ECS, and it got its name because 
and it got its name because it was people’s use of cannabis that helped lead to its discovery.
We naturally produce these 
chemicals all the time.
The chemicals THC and CBD from cannabis plants also affect our ECS 
and can have various effects on our bodies; 
and that’s why scientists are now researching potential treatments using them.
At this stage it looks fairly positive that it might help me and it might be a good
impact on me, but I am still really 
keen to see what is inside
what I've bought and how much
 CBD is in it.
My bottle's been opened
and passed around a little bit
so I bought a new bottle
to do the testing on
to make sure that it wasn't
contaminated in any other way.
And can this machine tell us what other chemicals might be in the CBD?
While CBD and THC are the big 
main ones it also
looks for other THC precursors
within your product.
While CBD oil is legal
that does depend on how much THC?
It varies depending on your product.
No matter if you had a one mil 
bottle, or a one litre bottle
you'd only be allowed 
one milligram of THC.
Right now in the UK there isn’t regulation or manufacturing standards 
specifically made for CBD supplement products.
But there is a law that means the amount of THC, that’s the psychoactive chemical 
that gets you high,  must be less
 than 1mg per item. 
And it doesn’t matter how big the 
bottle or product is,
it can still only have 1 mg of THC
 in the whole thing.
There’s strict regulation around the type of CBD being used in medical studies
that you can’t buy online or in shops.
And there will probably be more official guidance and even laws 
around low dose products like 
CBD oil very soon.
So, are all CBD products in the 
UK tested and regulated
in the same way 
that we're doing now? 
So in theory yes. 
For every product released in the UK they would need to comply to labelling
standards they have the correct 
amount of CBD that they're
advertising within their product.
If you ever want to check a supplier should 
be able to provide you with a
certificate that says; 'We've had it tested
for this batch, this is what's in it'.
We ran a series of tests on the product and identified that the THC content within
the product was just over four
 times the legal limit.
So the legal limit is one 
milligram per container
and we identified just over four 
milligrams in this product.
Four milligrams of THC isn't 
going to do anything 
notable to a person. You'd have to have a considerable amount 
of THC in there for there to be
 a psychoactive response. 
We found that the
CBD content was pretty much spot on
to what they'd claimed on the product.
When you extract CBD from the hemp plant you end up with THC as 
a by-product, so it could be the 
extraction process wasn't 
as thorough as it should have been at separating the cannabinoids properly
It could also be a pure 
misunderstanding of the law. 
The problem is unless you know 
how to interpret it
it's just a page with 
a load of numbers on it.
So I think there needs
 to be a simpler way
of explaining this to the consumer 
that doesn't rely 
on complicated reports like this.
I would say to Natalie; 'don't worry, you know the THC content in there
is very, very low, don't fear CBD products as a result of this experience'.
And as the industry grows and
 becomes more mature 
brands will be explaining better
 to consumers about their products
and making sure that those products 
comply with all regulations.
From what I have learned so far, I don't think I'm ready to take CBD oil.
Just until a few more studies and tests 
have been completed.
I'd never say no to taking it, especially because it's becoming more prominent in the media
and in the research labs, so I'd definitely keep an open mind about taking it.
