[Explainer] why 1mL syringes cause overdoses and 0.3mL ones do not
why 1mL syringes cause overdoses and 0.3mL ones do not. If you already knew this, the post is not for you and you can scroll on. 1mL and 0.3mL. Those are measured, not estimated, and not rounded up in my favour. Spent 17 weeks confused about this until somebody drew the table for me. 5mg, 1mL, 5mg/mL, 2mg is 40…
