I couldnt agree more....... It certainly does for
alcohol. Mainly due to its zero order kinetics.. hence
the belief (at least legally) that one level equals
one response, but other illicit substances have very
complex kinetics especially ecstasy which has a
complex hepatic and to a certain extent renal
metabolism.
For alcohol, amount ingested correlates well with
serum levels, but for amphetamines there is huge
variation in kinetics from person to person and unlike
alcohol it isn't sold in metered doses, hence the
difficulty in adopting a specific law.
However, driving without care and attention (due to
any cause) is still an offence, but I believe carries
a lower sentance
