Choosing the Right Strength for You

Not sure what strength is best for you? Selecting the right CBD vape oil strength depends on various factors, including your individual needs, tolerance, and the desired effects. Here are some considerations to guide you:

  1. Start Low, Go Slow: If you’re new to CBD or high-strength vape oils, it’s advisable to start with a lower potency and gradually increase as needed. This allows your body to adjust and helps you find the optimal dosage for your own tolerance.
  2. Consider Your Purpose: Different strengths may be suitable for different purposes. If you’re using CBD for general wellness, a lower strength might suffice, while those seeking more targeted relief may opt for a higher potency.
  3. Consult with a Professional: If you have specific health concerns or are unsure about where to start, consult with a healthcare professional or a CBD expert. They can provide personalised guidance based on your individual circumstances.
