Cannabis use has health risks
The use of hash or weed (cannabis) can cause somebody to feel fine temporarily. The use of cannabis, however, also involves risks. It can have an adverse impact on the cannabis user’s mood and behaviour. Additionally, cannabis use can trigger psychotic reactions, such as anxiety, depression and schizophrenia, especially if used in large quantities.

Cannabis impacts concentration and the ability to respond
Cannabis use temporarily reduces concentration and responsiveness. Consequently, it may cause an impaired performance at work, at study or in traffic. Long-term and intensive cannabis use may also cause impaired cognitive functioning. In most cases, this effect disappears after stopping cannabis use (RIVM, 2016).
