Health authorities in UK have been regularly issuing warning against use of tan jab. Melanotan I and II used in these jabs can damage the immune and cardiovascular systems along with other problems. But it seems that people are not paying much heed to it as the number of reports of people using these tan jab is continuously increasing.

These tan jabs have not been properly tested. Some websites and tanning shops are selling these tan jabs illegally. Authorities are also worried about the increased risk of infections like HIV and Hepatitis C due to sharing of needles.

Michael Evans-Brown, from Liverpool John Moores University said: "Serious concerns exist about the quality of the preparations that are currently available - not only the drug content and dose, but also contaminants and sterility."

"Some users, especially those who are injecting drugs for the first time, are reusing or sharing injecting equipment, which places them and others at risk of infections, including blood borne viruses."
