She revealed that she did drink before going to Grahamstown but would now quit the habit because "alcohol is not a sexy look".
Ntsiki added that it was important for artists to look after themselves and have emotional support.
Ntsiki is the latest celeb to speak about the dangers of alcohol in the industry. Earlier this year, former TV personality Nonhle Thema told TshisaLIVE she had given up the bottle for over a year, explaining how common alcohol was in entertainment circles.
"In the entertainment industry, you are surrounded by alcohol and it is hard to say no. It is seen as cool to drink and get drunk. I tell people that you don't need alcohol to have a good time, it is a trap. Mandela didn't go to jail for 27 years for us to be drunkards."
