Hashish is generally more potent than regular cannabis because it contains a higher concentration of THC. The strength of hashish depends on the strain of cannabis used to make it and the method of extraction employed.
For example, dry-sieve hashish typically contains around 40-60% THC, while ice-water hashish can contain up to 80% THC. Due to its high potency, hashish is usually consumed in smaller quantities than regular cannabis.
