When you first see the weed be sure to have a good look at it, preferably in bright natrual light. Be aware of the various types of contaminant, you can get a rough idea by checking out the Image gallery at
www.bebo.com/gritweed .
The first type of contamination to be noticed was gritweed, this stuff was covered in tiny glass like particles hard ash cannabis gritweed contaminated found to be silica. Alough its not around much now its still worthwhile knowing how to test for the dreaded grit weed. If you use one of the metal herb grinders you may notice unusual screeching or scraping, the grit may even leave marks on your grinder. If you suspect its gritweed dont put it near your mouth to test for a crunch instead give it shake over a surface you dont mind being scrapped like a blank cd. Then roll a glass over whatever crystal has fallen onto the cd. Listen carefully and if you hear crunching you know its gritweed.
One of the best ways to test is to look at the stems, scrape the stem with your nail and see if anything flakes off , if it does then you know its been coated with some type of substance. Theres not much crystal on the stems if any so when it looks like there is its an obvious giveaway that its been adulterated, you may see fine hairs which is normal.
You may come across weed that when burnt the ash becomes hard, flicking the ash may result in the head of your joint falling off. Rubbing this hard ash on fingers leaves a black oily residue not associated with clean cannabis or tobbaco.
Sweet bud, sugar bud, sugar weed whatever you want to call it will smell similar to candy floss when burnt and will be sweet to taste with your tounge( I dont recommend putting anything near your mouth if you dont know where its come from).
I doubt that I have coverd all forms of contamination in this artcile, if you know of any other tests, tips or even pictures please leave a comment.
