Always Inform Your Doctor

Tell all healthcare providers about your cannabis use, including dosage, frequency, and product type.

Start Low, Go Slow

Begin with minimal cannabis doses when taking medications and increase gradually over days to weeks.

Monitor for Changes

Watch for unusual symptoms, side effects, or changes in medication effectiveness after starting cannabis.

Timing Matters

Consider spacing cannabis use and medication doses by several hours when possible to reduce peak interactions.

If you are managing drug interactions, product consistency is essential — an inconsistent CBD dose can unpredictably affect drug metabolism. CBDWellness and CBDDR use standardized cannabinoid ratios with batch-level COAs, so you know exactly what you are taking.
