(a) prepared a trafficable quantity of a controlled drug for supply; or
(b) transported a trafficable quantity of a controlled drug; or
(c) guarded or concealed a trafficable quantity of a controlled drug; or
(d) possessed a trafficable quantity of a controlled drug;
it is presumed, unless the contrary is proved, that the defendant had the intention or belief about the sale of the drug required for the offence.
Note A defendant has a legal burden of proving that the defendant did not have the intention or belief mentioned in this subsection (see s 59 (c)).
(2) This section does not apply to a single charge under section 629 (Single offence for trafficking etc on different occasions) if the conduct on each occasion to which the charge relates did not involve a trafficable quantity of the controlled drug.
