Botulinum is the most severe toxin involving acetylcholine as it causes botulism, which results in muscle paralysis and respiratory failure as it inhibits the release of acetylcholine from nerve endings. Prairie rattlesnake venom and black widow spider venom also affect the release of acetylcholine, but their effects are less severe than botulinum. Hemicholinium-3 (HC-3) is an inhibitor of the choline transporter, which is involved in the synthesis of acetylcholine, but its effects are not as immediate and severe as those of botulinum.
