Choosing the percentage of CBD in your vapes depends on your personal preferences and experience with CBD. If you are a beginner, you may want to start with a lower percentage and gradually adjust according to your needs. If you are a regular user or are looking for a more pronounced effect, you may want to opt for a higher percentage. Also consider your specific goals and flavor preferences when choosing the percentage of CBD in your vape. It is always advisable to start with a lower dose and gradually increase if necessary.
