In section 5 (restriction of possession of controlled drugs), after subsection (4) insert—
“(4A)In any proceedings for an offence under subsection (3) above, if it is proved that the accused had an amount of a controlled drug in his possession which is not less than the prescribed amount, the court or jury must assume that he had the drug in his possession with the intent to supply it as mentioned in subsection (3).
(4B)Subsection (4A) above does not apply if evidence is adduced which is sufficient to raise an issue that the accused may not have had the drug in his possession with that intent.
(4C)Regulations under subsection (4A) above have effect only in relation to proceedings for an offence committed after the regulations come into force.”
