HASHIt can be very difficult to assess hashish for quality and effect. Cannabis flowers possess obvious characteristics such as aroma and crystal coverage to indicate their quality and potency. Hashish does not provide such obvious clues, and may also contain contaminants if produced in poor conditions.
How to assess the quality of hashish
In this article I am generally assuming “hashish” to mean traditional types such as dry-sift or hand-rubbed, rather than the high-strength solvent extracts so popular today. However, I have also made some mention of ice-o-lator hash (now also known as “solventless” extract) as it is common in the Dutch coffeeshops, and also can be assessed in similar ways to traditional hash.
In the coffeeshops, it is not always possible to subject your potential hashish purchase to rigorous checks. Some of these checks include handling the hashish, and many coffeeshop “dealers” generally try to prevent their products being handled in case of dirty or perfumed hands compromising its quality. But if you can’t touch it yourself, you can at least ask the dealer to demonstrate.
