Question 22

Syringes and needles used by the youth for taking the drug could prove to be very fatal. Why?

Answer

Those who take drug intravenously (direct injection into the vein using needle and syringe), are more likely to acquire serious disease like AIDS and Hepatitis B. The viruses which are responsible for these diseases,are transferred from one person to another by sharing of infected needles and syringes. Both disease are chronic infections and ultimately fatal. AIDS can be transmitted to one's life partner through sexual contact while Hepatitis B is tranmitted through infected blood.
