The Cannabis Plant

is one of the oldest domesticated crops. Throughout history, all civilisations have grown different varieties of cannabis for both industrial and medicinal uses.

The cannabis plant contains unique compounds called cannabinoids. Current research has revealed over 60 different cannabinoids so far. THC is the most abundant constituent of the cannabis plant, and the most well known. THC is responsible for causing the marijuana high.


This strain of the cannabis plant is grown for industrial uses such as foods, oils, textiles and ropes etc. It is a much taller and sturdier version of the plant. It is generally much thinner with smaller and fewer attention-grabbing flowers. It has been bred for many generations with other plants with similar characteristics, leading to the type of cannabis we now know as hemp.

Hemp contains no, or very little THC, the psychoactive chemical. Marijuana on the other hand contains high levels of the psychoactive chemical. This single difference is what most relies on to distinguish between hemp and marijuana.

The lawmakers don’t care about how tall the plant is, or even how many flowers it produces. They care whether the public can get high from smoking it or not.

Therefore, the UK has set the maximum THC content of hemp at 0.2%. Any cannabis with higher THC is considered marijuana, and is therefore considered illegal.


This strain of the cannabis plant is grown for medicinal and recreational purposes. It has flowering buds and is smaller than hemp.

It is high in Tetrahydrocannabinol (THC), the psychoactive chemical responsible for causing the Marijuana high. And it is prohibited under current UK legislation.


Cannabidiol (CBD) is not considered a controlled substance in the UK, and is therefore 100% legal.

Tetrahydrocannabinol (THC) is the psychoactive chemical responsible for causing the marijuana high, and is illegal.

The UK has set the maximum THC content of hemp at 0.2%. Therefore, any Hemp oil with higher THC than 0.2% is considered medical marijuana instead, and is therefore illegal under current UK law.
