We've been selling CBD for years, and we still refuse to present it as a sleeping pill. It's not false commercial modesty: it's because science, looked at honestly, doesn't allow us to go further than that. Here's what studies really show, without the usual marketing wrapping.
An indirect mechanism, not a sedative
CBD doesn't act directly on sleep the way a classic sleeping pill would. Its effect follows a more indirect route: reducing anxiety, lowering stress, easing certain kinds of discomfort – three common causes of bad nights. In practice, CBD doesn't make you sleep; it potentially removes what stops you sleeping. The nuance matters: if insomnia has nothing to do with anxiety or stress, the effect has much less reason to be there.
It works better for some types of insomnia than others
The most consistent data concern insomnia linked to anxiety or stress, where CBD has a plausible action through its indirect mechanism. For so-called primary insomnia, with no identified cause, the evidence is much thinner. In other words, CBD probably isn't the solution for everyone, and certainly not for all types of insomnia.
What health authorities say
Public health bodies remain cautious on this subject. In France, the national health insurance states that no solid scientific evidence currently confirms CBD's effectiveness against sleep disorders. The Mildeca, for its part, points out that results from existing studies remain mixed, and that some are statistically close to a placebo effect. It's not a condemnation of the product – it's a reminder that research hasn't settled the question yet.
"We'd rather tell a customer clearly that it may help, with no guarantee, than sell them a promise we can't keep," says Cyril Piaget, founder of Tiny Green. "Some feel a real difference from the first week. Others much less. We'd rather be honest about that than sell dreams."
What remains unclear: CBN
CBN, another cannabinoid sometimes presented as sedative, suffers from the same problem on a larger scale: scientific data are still very limited. A preliminary study of just twenty people showed a positive effect on the time taken to fall asleep – encouraging, but far from enough to draw a general conclusion.
CBD may help some people sleep better, especially when insomnia comes from anxiety or stress. But it isn't a scientifically validated treatment, and presenting it as a guaranteed solution would be dishonest. The best way to find out if it works for you is still to try it over several weeks, without expecting a miracle on the first night.
