There is a line in regard to the Swiss human rights approach.

We have spoken about "self-administered" or "physician-administered" but we have not ever spoken about what exactly is administered and what that process is. Dr. Nitschke goes into it in a number of parts of his opening statement. He stated:

...the prescription of the pentobarbital remains the task of [the] medical [profession]. However, there is no requirement under any Swiss law or regulation that prescription substances must be used.

Does that mean off-license or unlicensed drugs are used? What exactly does that mean?
