A man was told in Sarnia court Wednesday that the butane-modified version of marijuana resin in his possession will not be legalized as part of a government proposal.

A 25-year-old Sarnia man pleaded guilty to possession of a cannabis resin.

On June 25 police stopped a vehicle that smelled of burnt marijuana. The unlicensed driver was arrested.

The 25-year-old was a passenger and admitted ownership of two containers holding a total of approximately one gram of resin. The estimated street value was $70.

The resin was a version called shatter. It has a higher concentration of the active ingredient in marijuana. The yellowish oil is produced by processing marijuana with butane. After the oil hardens it can be shattered.

People using the drug may not ready for the impact of shatter’s higher level of the active ingredient, THC, said federal prosecutor Michael Robb.

The 25-year-old had no criminal record, said Robb in support of a discharge conditional on completion of six months of probation.

The probation is intended to discourage the man from further involvement with shatter, a product that will not be approved in the federal government’s move to legalize marijuana, said Robb.

Justice Mark Hornblower also told the man that shatter would not be legalized.

During the discharge probation, that will eventually leave the man without a criminal record, he must stay away from drugs and do 10 hours of community service.

It is The Observer’s policy generally not to identify people who are granted discharges.
