Yes, hash potency has higher concentrations than weed flowers (buds) because it contains compressed resin of the herbal cannabis plant. This means it includes a higher marijuana potency compared to the plant's flower.
The exact potency can vary based on the production method and the buds' quality. The effects you experience on both product types, such as distorted perception, diminished problem-solving capacity, euphoria, bliss, or sedation, will depend on the dosage.
