"Judging hashish gets as complex as judging wines! Here's one way of avoiding the cannabis dregs.

Pinch a small lump of hash (about the size of a matchhead) on to a flat enamel surface or ashtray, and play the flame of a lighter over the hashish for a few seconds.

If it's GREAT hash it will light on the first or second attempt. The harder the piece of hash is to light, the more likely it is that you've been sold a 'lemon'.

Once you've got your test piece of cannabis in flames, let it burn for a couple of seconds and blow it out. The embers should glow evenly like fine incense or a hot coal. The smoke it gives off should be milky white to blue grey with a heady, rich and sweet aroma. If you can smell rubber, this is never good, and is another exellent indication that you've been shafted.

Once your hashish tester has burnt completely, you should look for a fine white ash. If it's too dark, this indicates contaminants. These can be anything from waste leaves to car oil!!!
Around the ash, a ring of oil will form. The more oil and the lighter it's colour, the purer and higher quality your hash.

The secret 'recipes' of Moroccan hash-making are jealously guarded. Some include honey; others use old car tyres. As a general rule of thumb, if it's easy to crumble when at room temperature and gives a rich aromatic smell, then it's more than likely to be okay gear. If it's got more in common with the consistency of a brick, and no real smell, leave well alone.

Smell and taste aside, some simply believe that if it gets you stoned and makes you smile, it's good hash."
