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 |
