Canadian researchers conducted a controlled crossover trial of
4 different herbal cannabis preparations among 8 experienced
and authorized cannabis users with chronic pain. Preparations
were varied with respect to particle size, THC content and
humidity. Subjects received each preparation on a separate day
and prepared the drug in their usual way. They were asked to
evaluate the products based on appearance (smell, colour,
humidity, particle size, ease of preparation and overall
appearance) and smoking characteristics (burn rate, hotness,
harshness and taste). Particle size was defined as the size of the
particles after grinding the raw herbal material.
Seven subjects completed the study, and the product with
highest THC content (12 per cent), highest humidity (14 per
cent) and largest grind size (10mm) was rated highest overall.
Significant differences were noted between preparations on
subjective ratings of appearance and colour. Researchers
concluded that a "more acceptable cannabis product may
increase recruitment and retention in clinical studies of medical
cannabis." They noted that in September 2006 about 20 per
cent of authorized cannabis users obtained herbal cannabis from
Health Canada, compared to about 10 per cent in September
2004.
