What is CBD?

Cannabidiol, or CBD, is a key ingredient found in cannabis, the same plant that marijuana comes from. It's often recommended for treating different health problems. The strongest scientific evidence shows that CBD can be helpful for severe childhood epilepsy conditions like Dravet syndrome and Lennox-Gastaut syndrome. CBD has become popular because it offers relief from pain and other symptoms without making you feel high like marijuana does or causing the side effects that some medications do. You can take CBD in different ways, like inhaling it through vaping or eating it in the form of gummies.

How Long CBD Stay in Your Hair?

Hair tests are commonly used because they can show if someone has used drugs for a long time. CBD can show up in hair tests for as long as three months after the last time it was used. But tests specifically for CBD and THC in hair are very uncommon.

THC can be found in the blood for around five hours after using it, but CBD can stay in your blood for up to seven days.

Saliva tests can pick up CBD use shortly after you've used it, but they're not commonly used for work or legal reasons. Depending on how often you use CBD and how much you take, a saliva test could detect CBD in your system for up to 24 or 36 hours after your last dose.
