Prime Minister Tuilaepa Sailele Malielegaoi said on TV3 Samoa that there was a need to reconsider penalties of drug convictions.
His remarks follow a seizure last week at the wharf where Police confiscated 900 grams of methamphetamine.
A December bust found some 500 grams of the same drug, which the Ministry of Customs and Revenue said was a record haul for law enforcement.
"This is not a new issue and under the current law, it says that a fine (of) up to $100,000 (can be imposed). The key word is 'up to' meaning there can be no fine," Tuilaepa said.
