ADVANCED BUDTENDER CERTIFICATION (ABC)
1. Which plant species is the primary source of the regulated cannabis
products sold in licensed dispensaries?
A. Linum usitatissimum
B. Cannabis sativa L.
C. Cannabis ruderalis var. hops
D. Humulus lupulus
B. Cannabis sativa L.
Most botanists now treat sativa, indica and ruderalis types as varieties of
the single species Cannabis sativa L.
2. The glandular structures on cannabis flowers that produce most
cannabinoids and terpenes are called:
A. Stomata
B. Capitate-stalked trichomes
C. Calyx bracts
D. Cystolith hairs
B. Capitate-stalked trichomes
Capitate-stalked trichomes hold the resin heads where cannabinoids and
terpenes are synthesized and stored.

3. Retail cannabis flower is harvested almost exclusively from which
plants?
A. Hermaphroditic seedlings
B. Pollinated female plants
C. Unfertilized female plants
D. Male plants
C. Unfertilized female plants
Unpollinated females (sinsemilla) put their energy into resin rather than
seed production.
4. The colour change of trichome heads from clear to cloudy to amber
is used by cultivators mainly to judge:
A. Harvest timing
B. Water content
C. Pesticide residue
D. Nitrogen deficiency
A. Harvest timing
Trichome maturity is a common visual cue for deciding when cannabinoid
content has peaked.
5. What is the main purpose of curing cannabis flower after drying?
A. To raise the THC percentage tenfold
B. To improve flavour and smoothness while preserving terpenes
C. To remove all moisture completely
D. To sterilize the flower of all microbes
B. To improve flavour and smoothness while preserving terpenes
A slow cure lets chlorophyll and sugars break down and keeps the
volatile terpenes intact.
6. The term 'cola' refers to:
A. The main flowering cluster at the top of a branch
B. The fan leaf at the base of the plant
C. A type of cannabis beverage
D. The root ball of a clone
A. The main flowering cluster at the top of a branch
The cola is the dense terminal bud site on the main stem or a branch.

7. A 'phenotype' of a cannabis cultivar describes:
A. The packaging label
B. Only the THC percentage
C. The legal classification of the strain
D. The observable traits produced by genetics interacting with
environment
D. The observable traits produced by genetics interacting with
environment
Phenotype is how the genotype actually expresses itself under specific
growing conditions.
8. Which growth habit is most associated with traditional 'indica' type
plants?
A. Tall, lanky plants with very narrow leaflets
B. Vines with tendrils
C. Plants that flower regardless of light cycle
D. Short, bushy plants with broad leaflets
D. Short, bushy plants with broad leaflets
Indica types are typically compact with wide leaflets and shorter
flowering times.
9. Autoflowering cannabis varieties inherit their trait of flowering by
age rather than light cycle from:
A. Hemp seed oil
B. Tetraploid breeding
C. Gibberellin sprays
D. Cannabis ruderalis genetics
D. Cannabis ruderalis genetics
Ruderalis populations evolved to flower on a timer, and breeders crossed
that trait into modern lines.

10. Why are 'sativa' and 'indica' labels considered unreliable predictors
of a product's effects?
A. Sativa products are always CBD-dominant
B. Indica plants contain no THC
C. Effects depend more on cannabinoid and terpene profiles than on plant
shape
D. The labels are always reversed by growers
C. Effects depend more on cannabinoid and terpene profiles than on
plant shape
Decades of crossbreeding mean the chemical profile, or chemovar, is a far
better guide than lineage labels.
11. The best term for describing a cannabis plant by its chemical
composition is:
A. Cultivar code
B. Clone
C. Landrace
D. Chemovar
D. Chemovar
A chemovar groups plants by measured cannabinoid and terpene content
rather than appearance.
12. A 'landrace' strain is one that:
A. Was created in a laboratory
B. Is grown hydroponically
C. Developed naturally in a specific geographic region over generations
D. Contains only CBD
C. Developed naturally in a specific geographic region over
generations
Landraces adapted to local climates, such as Afghan or Thai lines, before
modern hybridization.
