SMOKING SOAP = SMOKING POISON

Recently RED EYE EXPRESS magazine highlighted the DANGERS of smoking bad quality hash, some of which contains very little cannabis at all. We refer to both "Soap" and the soft black gunk often referred to as "Squiggy Black", "Affy Black" or "Pakki Black". The article explained that even the better soap bars weighing about 250 grams contain less than 10 grams of cannabis pollen (resin glands) and up to 200 grams of ground-up shade leaf, along with various noxious substances like glue to bind it, and colouring agents.

Here are some of the other substances found in this bad quality cannabis sold by rip-off dealers:

beeswax, boot polish, animal turds, turpentine, henna, ground coffee, milk powder, pine resin, barbiturates, ketamine, aspirin, glues & dyes, Carcinogenic solvents such as Toluene and Benzene and many other unidentified and possibly DEADLY chemicals.

These SOAP bars are not available from coffee shops in Holland or from farms in Morocco. They are often made in Spain or England.

SOAP bar costs about £1,500 a kilo in the UK, that's £1.50 a gram: that's £5.25 an EIGHTH
If you buy it you are allowing yourself to be RIPPED OFF by unscrupulous dealers who either do not know or do not care about you and your health and may be interested only in the HUGE PROFITS they make.
SOAP is poisonous - it is a danger to health and it gives real cannabis a bad name. It should always remain illegal.
The ONLY way to stop this is to tell your dealer and REFUSE TO BUY BAD QUALITY

Anthropology and forensic science combine in a long overdue research project to uncover the hidden horrors of 'Soap'.

Neil Montgomery a Social Anthropologist doing doctoral research at Edinburgh University has teamed up with GW Pharmaceuticals to survey and analyse the numerous impurities that permeate the poor quality cannabis resin that is the most commonly available form of cannabis used in the UK. Known as "Soap Bar", due to the shape of the quarter-kilo bars it is formed into, this notorious 'hash' has for a long time had the reputation among cannabis users of being little more than poison; a noxious substance that has been tolerated because nothing else was available.

Anecdotes speak of the stuff being mixed with rubber, plastic, wax, diesel, soil, molasses, ghee, even boot polish, and the list goes on. While investigating potential sources of 'soap' samples, CRISP (Cannabis Resin Impurities Survey Project) has started to collect 'soap' stories; anecdotes about suspected contaminants and unpleasant side-effects. The end result of CRISP will be a rigorous forensic analysis of the chemical constituents of 'soap' woven through an appreciation of notions, perceptions and recollections of 'soap' drawn from Montgomery's broader ethnography on the use of cannabis. This crucial research hopes to illuminate the health hazards associated with what has become the staple in the diet of UK cannabis consumption and link the gradually developing awareness of the quality of 'soap' with the recent increase in the home cultivation of cannabis plants.
