So much for high times.
Harry Potter star Jamie Waylett, known as bullying Hogwarts student Vincent Crabbe, was arrested on Tuesday in London on suspicion of possessing marijuana.
According to British reports, police first stopped Waylett, 19, and a pal while they were driving and discovered eight bags of pot inside the vehicle.
Police then raided the London-area home the actor shares with his mom (and two brothers and a sister) and found 10 plants, believed to be cannabis and valued at about $2,900.
The plants were growing under powerful hydroponic lights beside a PlayStation, according to reports.
Waylett is due in court in July -- the same month Harry Potter and the Half-Blood Prince hits theaters.
