Tilburg Mayor Peter Noordanus decided to allow patients using medical marijuana to grow it themselves at their homes in the city, he wrote in a letter to the patients group for medicinal marijuana users PGMCG. Conditions include that patients are not allowed to cultivate more than five plants. They also need a prescription from their doctor, have to be a legal adult and make sure that their cultivation does not cause a fire hazard. They are also not allowed to sell the cannabis they grow. While growing marijuana is illegal, the court frequently decides to impose no penalty for it.
