there are a number of disabilities for which alternatives to plastic straws range from simply not useful to actively dangerous--nor do any of the alternatives have all the benefits^1^ for disabled people as a plastic straw does--and as mentioned they contribute rather negligibly to overall plastic pollution, so the wide consensus in the disability community is that plastic straw bans should either not be implemented or have significant carve outs for disabled people:

Full bans on single-use plastic straws have faced opposition from disability rights advocates, as they feel that alternative materials are not well-suited for use by those with impaired mobility (caused by conditions such as cerebral palsy and spinal muscular atrophy). Some with neuromuscular disabilities may rely on a plastic straw for its heat resistance and due to an inability to lift a cup.[118] [...] In particular, not all people with disabilities may be capable of washing reusable straws, straws made from inflexible materials are not capable of being repositioned, paper straws lose their firmness over time when soaked in a beverage, and straws made from hard materials such as metal can cause injuries. Advocates have preferred laws that still allow plastic straws to be offered upon request.[59][60][120][121]
