Former minister Gonen Segev was released from jail on Monday after a committee knocked off 19 months from his five-year sentence for drugs smuggling offenses.
Segev started his sentence in June 2004 after he was convicted of attempting to smuggle 32,000 Ecstasy pills into Israel.
Segev was also convicted of forging a diplomatic passport and using it on two occasions.
The prosecution did not oppose the committee's decision to shorten Segev's sentence for good behavior.
Segev was jailed at the Sharon Prison, where inmates enjoy a relatively comfortable life as they are allowed to leave the facility to work in a factory for most of the day.
