The amount of THC in a single puff from a UK-legal vape is extremely small. 1 ml vape last for about 200 to 300 puffs, so each puff provides about 0.005 mg barely.
These products are regulated so the total content across the entire cartridge is minimal. A puff delivers only a fraction of this, so users will not feel intoxicated.
The exact amount varies with cartridge size and design, but all remain within compliance. UK-legal THC vapes provide flavour and subtle effects without measurable impairment.
