How Long Does it Take for CBD to Work? The Onset and Duration of CBD

CBD, or cannabidiol, has become a popular supplement used to promote overall wellbeing. But how fast does it take effect and how long do the benefits last? Here’s a look at the typical onset and duration of CBD.

CBD Onset Time

When taken orally in the form of CBD oil, CBD capsules, or edibles, CBD is absorbed through the digestive system. This means it can take some time before you feel the effects. The onset of CBD ingested orally is usually between 30 minutes to 2 hours.

The time it takes for CBD to start working depends on:

  • The method of consumption
  • Size of the dose
  • Whether taken on a full or empty stomach

Oral forms of CBD that get absorbed in the mouth, like tinctures and sprays, can kick in faster at around 15-45 minutes. This quick absorption allows the CBD to enter the bloodstream directly through blood vessels under the tongue.

Duration of CBD Effects

Once the CBD kicks in, effects typically last 2-6 hours. The larger the dosage, the longer the duration. For example, a small 5mg dose may wear off in 2-3 hours, while a larger 40mg dose could provide benefits for 4-6 hours.

Consuming CBD on a full stomach or with fatty foods can increase the duration slightly as it slows digestion and absorption into the bloodstream. Ongoing benefits require re-dosing CBD throughout the day either as needed or at regular intervals.

Long-Term Effects

With regular use, CBD can provide lasting effects that build up over weeks or months of use. CBD may help minimize symptoms of chronic health conditions over time. It can also promote long-term benefits like:

  • Decreased inflammation
  • Improved sleep quality
  • Reduced anxiety
  • Enhanced mood
  • Pain relief

These effects become more pronounced with consistent use. Maximum CBD levels are eventually reached in the bloodstream so less is needed over time.

Tailoring Dose to Symptoms

The effective dose and duration depends on your unique body chemistry. Pay attention to how you feel a few hours after taking CBD. This helps you find the optimal dose and frequency. If effects wear off too soon, try a higher dose.

Track how long the benefits last and time your next dose accordingly. Finding the sweet spot with CBD is a process of experimentation. Adjust the dose and delivery method until you find what works best for your needs.

Be patient when first taking CBD and allow time to see how each dose impacts your symptoms long-term. Start low and go slow with CBD to discover how it affects you.
