It was then discovered that she had imported small amounts of the dangerous drug on several occasions from January last year until her actions were uncovered.
Jacobs originally appeared in court in Christchurch where she worked at an early childhood centre that cannot be named for legal reasons before he sentencing was transferred north.
The centre has previously confirmed to APNZ that Jacobs resigned shortly after her arrest from her job, which she'd held for about a month.
Outside court today, Jacobs declined to comment on her sentencing.
Although her practising certificate expired in December, Jacobs still appears on the New Zealand register of teachers, with a note saying she has voluntarily agreed not to teach pending the completion of a conduct investigation.
Teachers Council director Peter Lind said the organisation was yet to receive official notification of Jacobs' conviction. Once that happened, a formal process would begin.
``That doesn't mean to say it has to be delayed in any type of way.''
Dr Lind said in the case of disgraced former Northland deputy principal James Parker, sentenced to preventive detention for sexually abusing pupils, the disciplinary committee acted quickly via teleconference to remove his registration. That could happen in Jacobs' case.
