The basics
What THC vapes are
THC vapes are legal prescribable medical cannabis treatment options in the UK. They come in two pieces:
The THC vape cartridge: A sealed, prefilled cartridge that contains a prescribed cannabis extract with a defined and clearly printed cannabinoid profile.
The vape pen or device: A compatible, rechargeable battery device that the cartridge screws or clicks into. When switched on, the battery heats the extract to the point where it vaporises, and this vapour is then inhaled.
You may also see a THC vape pen described simply as a THC pen.
How it's used
Using your prescribed THC vape pen
A prescribed THC vape cartridge screws or clips onto a weed vape battery or device, which heats the extract in the cartridge to the point where it vaporises but does not combust. This ensures that the therapeutic compounds, in this case cannabinoids and terpenes, are released as vapour rather than smoke, which you then inhale through the mouthpiece.
Fit the cartridge
Your legally prescribed THC cartridge needs to be fitted to the vape pen.

Review the effects
At your subsequent follow-up appointments, explain to your doctor how you are getting on and how the THC vape is working for your health needs, so they can review all treatment options.

Dose consistency
Pre-filled THC vape cartridges deliver a very consistent dose. Each cartridge contains a regulated and specified amount of the target cannabinoid, making dosing consistent from one administration to the next.

Discretion and practicality
Unlike flower, THC vapes do not need to be prepared before each dose. They are designed to offer a discrete, easy to administer, and convenient option that is easy to dial the dose in for consistent effects on the go.
