Joe Forrestal’s 8in marmoset Caesar inhaled super-strength skunk while he was kept in a cage.
Vets who found the tiny primate discovered traces of cannabis in a sample of his fur and believed he was suffering from the effects of it.
Caesar was also so lonely and depressed he let out squeals in a bid to find friends, a court heard.
Convicted drug dealer Forrestal, 23, has now been banned from keeping pets for five years and ordered to pay £1,410 in fines and costs after admitting two charges of failing to ensure his pet’s welfare.
He was also accused of poisoning the monkey with the cannabis but prosecutors dropped that charge because they could not prove he did it deliberately.
