Some people assume CBD hardware is fixed, but many devices have an adjustable airflow ring or slider near the mouthpiece or base. It might be subtle, but it's there. Check your device manual or look for a small rotating ring. If you're not sure, a quick search for your model can clear it up.

If your device truly has no adjustment, you can still manage heat issues by taking shorter, slower puffs. That gives the coil less time to over-saturate.
