A doctor at Hassaf Harofeh Medical Center in Rishon Letzion provided medical marijuana to people who weren’t supposed to receive it, including some without medical problems, Army Radio reported on Tuesday.

The man, an expert on cancer, was ordered to stop his actions last month, after the hospital manager found out about them.

Medical cannabis is legal in Israel, albeit tightly controlled.

A recent study by the Health Ministry showed many patients became addicted to medical cannabis, and continued to use it after their treatment was finished.

Some of them turned to the black market when doctors refused to provide it. As a result, the ministry decided to open a special rehabilitation center for the people who started using the drug as a pain killer.
