• Getting ‘stoned’ on cannabis makes most users relaxed and talkative. It heightens the senses, especially when it comes to colours, taste and music.

• Cooking and eating hash makes the effects more intense and harder to control.

• Hash may bring on cravings for certain kinds of food. This is often called having the ‘munchies’.

• Cannabis lodges in the fatty tissues of the body, so it can be detected long after it was last used.

• Cannabis traces are detectable in the urine for up to three weeks in heavy regular users and in the hair for much longer.
