This information included participant age, gender,
and primary and ancillary dystonic diagnoses
RESULTS
Participant demographics
The survey included a total of 158 participants comprised
of responses from 133 cisgender female participants and 25
cisgender male participants with a mean age of 64.8 years
old and participant age ranging from 22 years old to 95
years old (Figure 1)
Adductor spasmodic dysphonia was
the most common condition with 65 participants claiming
this diagnosis (Figure 1)
Mixed spasmodic dysphonia was
found to be the second most common with 37 responses
claiming this diagnosis, and abductor spasmodic dysphonia
closely followed at 30 participant responses (Figure 1)

dystonia otherwise not specified were less common diag-
noses for this survey population (Figure 1)
A majority of
the respondents were not diagnosed with dystonia or
tremor elsewhere in their body, though 51 of the partici -
pants (32.3%) reported experiencing dystonia or tremor
beyond their vocal symptoms (Figure 1)
Participants using cannabinoid products to treat
vocal dystonia
Of the 85 (53.8%) participants who stated they had tried
using cannabinoid products at least once in the past to treat
their vocal condition (Figure 2A), 45 participants (52.9%)
stated they currently use cannabinoid products as treat -
ment (Figure 2A)
Among these participants, 24 partici -
pants (53.3%) used cannabinoid products daily (Figure 2B)
Eight participants used cannabinoid products once a week,
six participants used cannabinoid products multiple times a
week, and seven participants used cannabinoid products
more sparingly at once or twice a month (Figure 2B)
The
majority of participants reported using cannabinoid pro-
ducts to treat their symptoms for at least 1 year (58.8%)
with 28 of these participants (32.9%) reporting use for
approximately 1–2 years and 22 of these participants
(25.9%) reporting using for at least 3 years (Figure 2C)
Seventeen respondents reported using cannabinoid pro-
ducts for less than a month and 12 respondents reported
several months of use (Figure 2C)
Respondents were most likely to use cannabinoid pro-
ducts containing CBD alone (32 of 85 participants) or CBD
in combination with THC (39 of 85 participants) and were
less likely to use THC products alone (12 of 85 participants)
(Figure 3)
Among participants who actively used cannabi -
noids to treat their vocal condition, the most frequently used formulation of cannabinoid products was edible products,
with 29 respondents (64.4%) stating they used this pre-
paration (Figure 3)
Twelve participants who selected
“other” specified that they used a tincture preparation of
cannabinoids and one participant specified tablets, both of
which are oral formularies that can also be classified as an
edible cannabinoid product (Figure 3)
The second most
common mode of using cannabinoid products was via
smoke inhalation, with 16 participants (35.6%) using this
method (Figure 3)
Vaping was another common method of
using cannabinoid products with 10 participants (22.2%)
stating they used this formulation (Figure 3)
Topical can-
nabinoid products were the least commonly used product
with eight participants (17.8%) stating they used this pre-
paration; one participant who selected “other” specified that
they used CBD patches, which can be reclassified as a to-
pical preparation of cannabinoids (Figure 3)
Participants who did not use cannabinoid products
to treat vocal dystonia
Of the 158 respondents in total, 73 (46.2%) had never tried
using cannabinoid products to treat laryngeal dystonia/
vocal tremor/MTD (Figure 2)
Additionally, 40 re-
spondents stated they had tried cannabinoid products to
treat their condition but had since discontinued cannabi -
noid use (Figure 2)
The most commonly cited reason for
discontinuing cannabinoid use among respondents was the
ineffectiveness of these products in treating their under -
lying vocal condition, with 31 participants (77.5%) selecting
