When a person needs cannabis, they must first have a prescription from a doctor. It is an authorization and not necessarily a prescription. So we're talking, to use the exact terms, about a doctor's authorization. There is a process in place to verify whether this is a duly issued prescription. If the quantity of plants is high, if certain things do not seem quite legitimate, we follow a procedure that allows us to check the legitimacy of the prescription.
If we give our approval to a person whose prescription is legitimate, we then grant him a permit to grow plants at home. We have to ensure that the number of plants, in particular, corresponds to the prescription. A person cannot grow 200 plants if his prescription says 100, in which case it is absolutely clear that it is illegal. The police can then intervene, since this person goes beyond the scope of his or her permit.
