In the UK, it is only legal to buy THC vape pens if they meet the exemption rule of containing less than 1 mg of THC per container. Any vape that exceeds this limit is considered a controlled drug and can only be obtained with a valid prescription from a specialist doctor.
What this means for consumers
Most THC vape pens sold legally in the UK are “low-THC” products. They are carefully formulated to stay under the 1 mg threshold and do not cause intoxication. Stronger recreational-style vapes, common abroad, are illegal to purchase or possess without prescription.
