Bullfuckingshit. N butane has a higher boiling point than Iso butane so you would maybe have more residual solvent with the n butane than the iso butane. It's all about the proper purge. All the loop systems do is allow solvent recovery and lower incidence of flashing. But to say ISO makes poison and N butane does not just indicates you don't know jack squat.
you are correct.
The only difference between butane in a bic, and butane in a hospital is quality control and filtration for purification.
