Dacosta pleaded guilty to a variety of charges including possession of crack cocaine with intent to supply and possession of cannabis, heroin and crack cocaine.
Judge Robert Orme said he was jailing him for the shortest possible sentence as he had a young family and had shown he was trying to reform.
Dacosta told the judge that he had an eight-year-old daughter and a four-year-old son he wanted to care for.
He said he was concerned for his son as he was starting to show behavioural problems and did not want him to get into a life of crime as he himself had done.
