Decoding Cannabis: Over the limit, but not impaired? What the science shows

The UK (and many other countries) sets its drug-driving THC limit at 2 µg/L of blood, but is that a measure of impairment, or just detection? A 2026 simulator study found frequent cannabis users were no more impaired than non-users 12 to 15 hours after smoking, despite still exceeding that threshold. We decode what the research really shows, and why it is relevant for medical cannabis patients who are worried about getting behind the wheel.

For an increasing number of patients in the UK, medical cannabis is another tool that helps, and when it does, the people supporting them can feel the difference too. We surveyed 1,669 Releaf patients, and their answers point to a benefit that reaches beyond the patient alone.

Decoding Cannabis: what the first placebo-controlled cannabis migraine trial means for patients in 2026

The first randomised, placebo-controlled trial of vaporised cannabis for migraine attacks has finally been published.
