Myth #7: CBD Makes You Feel Sedated and Drowsy

Quick Fact

Does CBD make you tired? Not usually. At normal doses, CBD does not cause sedation. In fact, low to moderate doses are associated with alertness rather than drowsiness. If you feel sleepy after taking a CBD product, check the label — many CBD products are specifically formulated for sleep and include added melatonin or other sleep-supporting ingredients. The drowsiness is coming from those additives, not the CBD itself.

The Full Story

The drowsiness myth comes from two places. First, cannabis has a reputation for causing sedation — but that effect comes from tetrahydrocannabinol (THC), not cannabidiol (CBD). Second, many CBD products are specifically formulated for sleep and include added melatonin or calming botanicals, which do cause drowsiness.

Research on CBD’s effect on alertness is actually counterintuitive. At low to moderate doses, CBD appears to have a mild alerting effect. This is one reason many people take it in the morning for focus and anxiety management rather than at night.

Does CBD Make You Tired at Higher Doses?

At very high doses, drowsiness can occur — but those doses are well above what most people take in over-the-counter products. For the vast majority of users at standard amounts, tiredness is not a typical experience. That said, individual response varies, and some people do find that CBD makes them feel sluggish even at standard doses and without any added sleep ingredients. When you experience lethargy or sluggishness, it is worth trying a lower dose or switching to a different product type before writing it off entirely.

If you want CBD specifically for sleep, look for products that include melatonin or valerian root alongside it. If you want to use it during the day without drowsiness, stick to standard-dose isolate or broad-spectrum products without added sleep aids.
