A teenager hit a woman with a metal pole and went on a rampage of destruction after drinking and taking a "legal high".
In a small hours wrecking spree, Andrew Fettes-Hawkins (18) laid into a motorhome with the pole, causing £2,500 damage to the body panels, Leicester Crown Court was told.
The owner, a woman, got dressed and went out to confront him, but Fettes-Hawkins hit her around the ear before throwing the pole across the road and walking away.
He was so aggressive when police arrived in Fountains Avenue, Eyres Monsell, Leicester, they had to use an incapacitant spray on him, the court heard.
The stimulant had made him hallucinate and he feared he was in danger and being chased.
The 18-year-old , of The Meadows, Shepshed, admitted three counts of criminal damage, one common assault and possessing an offensive weapon, on April 28.
Victoria Rose, prosecuting, said at 4am, several residents were woken by the defendant's "erratic behaviour" in the street.
In addition to the motorhome, he smashed windows of two other vehicles.
"The police received reports from a number of people complaining about the disturbance and damage," said Miss Rose.
"The woman resident suffered a cut ear and a bruised head. She was attended to by an ambulance crew."
In interview, Fettes-Hawkins said he had been out the evening before and taken the legal high.
Miss Rose said: "The police said he was genuinely mortified and upset by his actions when told what he'd done."
The teenager was sentenced to a 12-month community order, with 150 hours of unpaid work.
He was also ordered to pay £400 compensation to the woman he assaulted.
Sentencing, Judge Nicholas Dean said: "It seems clear the taking of a legal drug and drink led you to behave in a bizarre, erratic and frightening way.
"What the police officers observed you doing must have been frightening because it appeared you were out of control.
"I accept it was wholly out of character and caused by the drug you took.
"But you're responsible for what you did because you had taken the drug, and that was bound to be unpredictable.
"From the outset, you've shown real remorse and it's unusual for the police to describe an individual being mortified by their actions."
Isabel Wilson, mitigating, said of her client: "He has written apology letters to the victims to be passed on to them.
"He expressed remorse as soon as he sobered up and the effect of the drug had worn off.
"He had been drinking to excess and took a legal high, which he had taken once before without any adverse effect.
"But it affected him differently and he began hallucinating about people chasing him and going through traumatic events.
"He was panicking and paranoid about being pursued and it was a distressing experience he will never repeat."
'Legal does not mean safe'Legal highs produce effects similar to illegal drugs but are not controlled under the Misuse of Drugs Act.
Because they are sold as legal, it does not mean they are safe, warns a drugs advisory website.
The contents can vary greatly and you cannot be 100 per cent sure what is in a legal high, or what effect it is likely to have.
A number of legal highs have been banned under the Misuse of Drugs Act, for example, Mephedrone.
Mixing legal highs with other substances, such as alcohol, can increase the risks.
Side effects include of psychosis, panic attacks, depression, heart problems, seizures, coma, loss of bladder function and even death.
Legal highs vary in potency and can easily be overdosed.
In an attempt to avoid legislative controls, some producers and suppliers are now manufacturing new drug variations.
