Today, Launceston's Supreme Court heard police searched Stephen John Jackman's High Street home on April 11 last year.

Crown prosecutor Luke Brett said Northern drug squad officers found 9.160 kilograms of dope, assorted by breed in some cases, in the home.

Mr Brett said the prosecution would argue Mr Jackman was intending to sell some or all of the cannabis or believed someone else would.

"This is simply far too much and far too valuable for personal use alone," he said.

The court heard cannabis could fetch between $200 to $300 an ounce.

However defence counsel Greg Richardson said  the cannabis found by the police included stem, stalk and leaf which is unsellable.

"I want to apologise," Mr Richardson said to the jury.

"This is going to be a really boring case."

Mr Richardson said the only issue in dispute was Mr Jackman's intent, which the defence argues was not to traffick.
