He, however, said that drug dealers, distributors, users of drugs are being arrested and the idea of the government is to ensure that illegal trade comes to an end in the country.
The Premier made the remarks yesterday in Dar es Salaam when handing over a vehicle to Rogers Siyanga, commissioner general for the Drug Control and Enforcement Authority (DCEA).
Majaliwa said that the government has gone extra-miles in the fight against illicit drugs, whereby recently had impounded a ship which was heading to Mozambique. The vessel was nabbed in the coast of Mtwara, and it was loaded with assorted illicit drugs.
"It is high time for the government to continue empowering DCEA and today we're handing over this new vehicle so that the authority accomplishes its tasks," he said.
He also urged Tanzanian to refrain from illicit drug trade, distribution as well as trafficking as the government was very keen to address the challenge.
According to the PM, the government is currently building laboratories under DCEA to test illicit drugs that would be seized.
He suggested the need for Tanzanians to cooperate with the government in addressing the vice.
For his part, DCEA boss, commended the government efforts towards empowering his authority, urging the public to refrain from the illegal business.
Apart from controlling the entry of the illicit drug, Sianga said that his office works hard to ensure that people are well informed on the negative impact of drugs and better ways of getting and using the drugs.
He also called upon the public to actively take part in the process of encouraging those who have been affected with drug use to get out of it.
